TRACTOR is the prime mover, including the en-
gine, drive train, operator seat, and controls to
operate the mower.
Walker Manufacturing recommends that any ser-
vice requiring special training or tools be performed
by an authorized Walker Mower Dealer. There are
several general practices to be aware of in the area
of safety. Most accidents associated with the oper-
ation or maintenance of a Walker Mower are
caused by disregarding basic safety precautions or
specific warnings. Such accidents, in most cases,
can be prevented by being aware of the dangers
present.
TRANSAXLE transmits and controls power
from the ground drive belt to the main drive
wheel.
TRANSAXLE LOCKOUT RODS release the
transaxles to permit freewheeling the tractor.
IDENTIFYING NUMBER LOCATIONS
The tractor serial number plate is affixed to the
tractor body just below the left rear corner of the
seat. The mower deck serial number plate is affixed
alongside the angle iron framing on the LH side of

adequate protective clothing, including long
pants. Wearing safety glasses, safety shoes,
and a helmet is advisable and required by some
local ordinances and insurance regulations.
11. Never attempt to make any adjustments
whiletheengineisrunning,exceptwherespe-
cifically instructed to do so.
12. The electrical system battery contains sulfuric
acid. Avoid any contact with skin, eyes, and
clothing. Keep the battery and acid out of reach
of children.
7. Prolonged exposure to loud noise can cause
impairment or loss of hearing. Operator hear-
ing protection is recommended. Wear a
suitable hearing protective device, such as ear-
muffs or earplugs.
WARNING
The engine exhaust from this product
contains chemicals known to the State of
California to cause cancer, birth defects
or other reproductive harm.
8. Keep all protective shields and safety de-
vices in place. If a protective shield, safety
device, or decal is damaged, unusable, or miss-
ing, repair or replace it before operating the
machine.
OPERATING
1. Operate the mower only in daylight or in good
artificial light with good visibility of the area being
mowed.
9. Be sure interlock switches are functioning
correctly, so the engine cannot be started un-
less the Forward Speed Control lever is in the
NEUTRAL-PARK position, and the PTO clutch
is in the DISENGAGED position. Also, the
engine should stop if the operator lifts off the
seat with either the Forward Speed Control
(FSC) out of the NEUTRAL-PARK position or
the PTO clutch in the ENGAGED position.
2. Sit on the seat when starting the engine and
operating the machine. Keep feet on the deck
footrests at all times when the tractor is moving
and/or mower blades are operating. Never
operate the tractor without deck or imple-
ment installed.
NOTE: There is a 1 to 1-1/2 second time delay
function on the seat switch to avoid engine
power interruption when driving over bumps.
3. For a beginning operator, learn to steer
(maneuver) the tractor with a slow engine
speed before attempting any mowing oper-
ation. Be aware that, with the front mounted
mower configuration, the back of the tractor
swings to the outside during turns.
10. Handle gasoline with care. Gasoline is highly
flammable and its vapors are explosive:
a. Use an approved fuel container.
4. Remember, for an emergency stop, the forward
motion of the tractor can always be stopped by
pulling the Forward Speed Control (FSC) into
the NEUTRAL-PARK position.
b. Never add fuel to a running engine or hot
engine (allow hot engine to cool several
minutes).
5. In case the transmission drive belt breaks during
operation, and if the machine is on a slope, the
machine will freewheel down the slope. To
maintain control, immediately (1) Release the
steering levers and simultaneously (2) Move the
FSC to the NEUTRAL-PARK position. When
the machine is stopped or moving slowly,
engage the parking brake.
c. Keep matches, cigarettes, cigars, pipes,
open flames, or sparks away from the fuel
tanks and fuel container.
d. Always fill the fuel tank(s) outdoors using
care. Fill to about one inch from the top of
the tank. Use a funnel or spout to prevent
spilling.
NOTE: This is exactly the same procedure
used to normally stop and park the machine.
e. Replace the machine fuel cap(s) and con-
tainer cap securely and clean up any spilled
fuel before starting the engine.

Safety Instructions
6. Disengage the blade clutch and put the FSC in
the NEUTRAL-PARK position before starting
the engine (an ignition interlock switch normally
prevents startingof the machine if these controls
are in the OPERATING position).
15. When using the tilt-up deck, observe the fol-
lowing recommendations:
a. Do not move tractor with deck in tilt-up
position.
b. Never tilt body forward with deck in tilt-up
position.
7. Do not run the engine in a confined area
without adequate ventilation. Exhaust fumes
are hazardous and can be deadly.

9. Watch for holes, rocks, and roots in the terrain
and for other hidden hazards. When mowing tall
grass, mow higher than desired to expose any
hidden obstacles. Then, clean the area and
mow to the desired height.
b. LOOKtomakesurebladedriveshaftmove-
ment has stopped before trying to unclog
the system.
c. Disconnect the spark plug wires.
10. Avoid sudden starts or stops. Before backing
the machine up, look to the rear to be sure no
one is behind the machine. Watch carefully for
traffic when crossing or working near roadways.
d. Never place hands under the deck - use a
stick or similar tool to remove clogged ma-
terial.
11. Disengage the blade drive when transporting
themachineacrossdrives, sidewalks, etc. Never
raise the mower deck while blades are
rotating.
17. If the cutting blades strike a solid object or the
machine begins to vibrate abnormally,
immediately disengage the blade clutch
(PTO), stop the engine, and wait for all
moving parts to stop. To prevent accidental
starting, disconnect the spark plug wires.
Thoroughly inspect the mower and repair any
damage before restarting the engine and
operating the mower. Make sure cutter blades
are in good condition and blade bolts are
12. The maximum recommended side slope
operating angle is 20 degrees or 33% grade.
When operating the machine on a slope, reduce
speed and use caution to start, stop, and
maneuver. To prevent tipping or loss of control
of the machine, avoid sharp turns or sudden
changes in direction.

13. Never adjust cutting height while the mower
is moving. Before adjusting cutting height or
servicing, move the Forward Speed Control
(FSC) into the NEUTRAL-PARK position,
engage the parking brake, and disengage the
blade clutch (PTO). Tractor should not be mov-
ing while adjusting cutting height.
18. Do not touch the engine or muffler while the
engine is running or immediately after stop-
ping the engine. These areas may be hot
enough to cause serious burns.
19. When leaving the machine unattended, disen-
gage the blade clutch (PTO), stop the engine,
and remove the key.
NOTE: The clutch brake should normally stop
drive line rotation within five (5) seconds of dis-
engaging the PTO clutch.
14. Do not operate with the grass deflector
chute removed. Keep the deflector in the low-
est possible position.

SETUP INSTRUCTIONS
Dry Battery Service
Walker Mowers are shipped partially assembled to
our distribution network, and are typically assembled
by the selling dealer. For any additional assembly
besides the following, contact your Walker dealer.
DANGER
Activating a battery can be dangerous.
The battery should be taken to a reliable
service station, battery store, or power
equipment dealer where a trained techni-
cian can activate the battery safely. DO
NOT attempt to activate the battery unless
you are experienced in battery service
work. The following activation and charg-
ing instructions are provided for use by a
trained battery technician.
Battery Service
Raise mower body up for battery access. Check the
battery for electrolyte level and charge. The
electrolyte level should be at the bottom of the vent
wells [1/4 to 1/2 in. (6 to 13 mm) above plates]. If the
specific gravity is less than 1.225, the battery needs
charging. If the battery has been shipped dry, or is
wet but needs service, refer to the following
instructions.
IMPORTANT: Make sure battery is securely
mounted in the frame. A loose battery may cause
damage to the case resulting in acid leakage and se-
vere damage to the machine. A hazard may be cre-
ated by damage to critical working parts and safety
systems.
DANGER
Battery electrolyte is a poisonous and cor-
rosive sulfuric acid solution.
• Avoid spillage and contact with skin,
eyes, and clothing - causes severe burns.
Wet Battery Service
Ifthebatteryhasbeenshippedwet,buttheelectrolyte
level is low or the battery needs to be charged then:
• To prevent accidents, wear safety gog-
gles and rubber gloves when working with
electrolyte.
1. Fill each battery cell with drinking water to the
bottom of the vent wells.
• Neutralize acid spills with baking soda
and water solution.
2. Charge battery. Refer to Battery Charging in
this section.
To fill (activate) battery with electrolyte (if battery has
been shipped dry):
1. Remove the battery hold-down bar, disconnect
the battery cables and lift the battery out of the
tray.
IMPORTANT: Battery must be removed from
the mower before filling with electrolyte.
IMPORTANT: Obtain and use only battery
grade sulfuric acid electrolyte with a 1.265 spe-
cific gravity to activate the battery. DO NOT use
water or any other liquid during initial activation.
2. Remove the filler caps and carefully fill each cell
until the electrolyte is just above the plates.
3. After the battery is filled with electrolyte, replace
the filler caps and charge the battery. Refer to
Battery Charging.

Battery Charging
DANGER
BATTERIES PRODUCE EXPLOSIVE GASES
• Charge the battery in a well-ventilated
area, so that gases produced while charg-
ing can dissipate.
• Keep sparks, flames, and smoking mate-
rials away from the battery at all times.
• Make sure the battery cap vents are open
after the battery is filled with acid (check
manifold vent on each cap).
Deck Caster Wheel Installation
• Make sure the battery charger is unplug-
ged before connecting or disconnecting
cables to the battery.
Deck Discharge Shield Installation
Attach the deck side discharge shield by positioning
the shield hinge lug in front of the deck mount and
fastening with two 3/8-16 x 1-1/4 in. bolts, 3/8-16
ESNA nuts, and 3/8 in. wave spring washers. The
wave washers fit between the two hinging surfaces.
Tighten the nuts until the shield moves freely but is
not loose.
1. Charge the battery at 15 amps for 10 minutes.
DO NOT exceed 20 amps maximum recom-
mended charging rate. Charge until specific
gravity is at least 1.250. Total charging time
should not exceed one (1) hour.
2. After charging the battery, adjust the electrolyte
level to the bottom of the vent wells [1/4 to 1/2 in.
(6 to 13 mm) above the plates].
WARNING
DO NOT operate the machine without the

2. Check the side-to-side level. Rotate the out-
side blades sideways and measure the
distance from blade tip to ground on each side.
If measurements vary more than 1/8 in. (3 mm),
adjust the height adjustment rod on the high side
to level the deck.
Deck Leveling
1. Position mower on a smooth, level surface. Set
the cutting height to the highest position - 5 in.
(127 mm) - for easy access under the deck to
measure blade height. Refer to ADJUSTING
CUTTING HEIGHT in Operating Instructions.
3. Check the front-to-rear level. Rotate the cen-
ter blade to point forward. Measure the
distance from blade tip to ground on the front
and rear. The rear of the blade should be 1/8 to
1/4 in. (3 to 6 mm) higher than the front of the
blade; remove the chain from the deck height
adjuster clevis and adjust equally to achieve at
least 1/8 in. (3 mm) difference. Reinstall
chains.
NOTE: A block of wood cut 5 in. (127 mm) high
is a convenient gauge to measure blade height
above ground during the leveling process.
WARNING
The machine must be shut off during this
procedure.
NOTE: The mower deck and support frame are
jig welded; within normal tolerances, very little, if
any, adjustments should be required to level the
deck. Tire pressure will influence the levelness
of the deck. Check the tire pressure as a possi-
ble cause of the deck not being level.

Operating Instructions
Engine Choke
Forward Speed Control (FSC)
The choke control lever (black knob) is located on
the left side of the seat. To start a cold engine, move
the choke control forward to the ON position. After
engine starts, move choke control toward the OFF
position, keeping enough choke to allow the engine
to run smoothly as it warms up. As soon as possible,
move the choke to the OFF position. A warm engine
requires little or no choke for starting.
Forward Speed Control (FSC) has two functions:
One is to set forward travel speed, and the other is
to establish the NEUTRAL-PARK position. When
the FSC lever is moved into the FORWARD position,
a friction lock holds any forward speed setting from
0 to 9 mph (0 to 14 km/h). The ground speed is pro-
portional to the lever position; the further the lever is
advanced forward, the faster the tractor moves. It is
not necessary to hold the FSC in position since the
friction lock maintains the selected lever position.
Pulling back on the steering levers overrides the
FSC setting and slows or stops forward travel.
Releasing the steering levers allows the tractor to
resume forward travel at the speed set by the FSC
lever. To stop and park the machine, the FSC lever
is moved backward to the NEUTRAL-PARK
position.
IMPORTANT: Make sure the choke is in the OFF
position during normal engine operation; running
with the choke in the ON position CAN damage the
engine.
Engine Throttle
The throttle control lever (red knob) is located on the
left side of the seat and is used to control engine
speed. Moving the lever forward toward the FAST
position increases engine speed; moving it back-
ward toward the IDLE position decreases engine
speed.
Steering Levers
Each drive wheel is controlled by its own indepen-
dent steering lever, for both steering function and
FORWARD/REVERSE motion. The FSC lever sets
the maximum forward speed, and also sets the for-
ward position of the steering levers. The steering
levers operate only with a backward pulling move-
ment of the lever, which causes the drive wheel for
that lever to first slow down, stop, and then reverse
with a full backward lever stroke. The levers are
released to the FORWARD position for “straight-
ahead” ground travel.
Throttle
Choke
NOTE: Pushing forward on the steering levers will
not cause any change in tractor motion - there will be
no steering lever reaction and there will be no
machine damage.
Choke and Throttle Location
Blade Clutch (PTO)
The blade clutch lever has two positions. Pulling the
lever FORWARD engages the PTO that drives the
mower blades. Pulling the lever BACKWARD
disengages the PTO and engages the blade brake.

Operating Instructions
Parking Brake
Hourmeter
The hourmeter, which is located on the right front of
the body, displays operating time accumulated
while the ignition switch is in the ON position.
The parking brake functions by locking a detent arm
internally into the transaxle. Moving the lever FOR-
WARD engages the parking brake; moving the lever
BACKWARD releases the brake.
The hourmeter provides maintenance reminders
after certain hours of operation. The hourmeter
screen will start flashing the reminder one hour prior
to the recommended interval and will continue until
one hour after the recommended interval (two
hours). The hourmeter does not have a manual
reset function.
IMPORTANT: Stop the tractor completely before
engaging the parking brake. The parking brake uses
a positive mechanical lock similar to the PARK posi-
tion on an automotive automatic transmission. If the
tractor is moving when the brake is engaged, it will
result in sudden stoppage and possible internal
damage to the transaxle.
Procedure

with the shoulder on the rod in the chassis notch, the
transaxles are released to permit freewheeling. By
releasing the rods and recessing them back toward
the chassis, the transaxles are engaged for normal
operation. The transaxle rods in the LOCKOUT
position are used to enable moving the machine
without the engine running (e.g., for service). Refer
to TRANSAXLE LOCKOUTS in this section for
operating instructions.

the engine manufacturers recommend engine
oil changes every 50 hours in extremely dirty
or dusty conditions or for units with less than
100 hours annual use.
NOTE: The transaxle lockout rods ends should be
completely retracted against the chassis, otherwise
operation of the transaxle may be erratic.

Operating Instructions
STARTING THE ENGINE
IMPORTANT: DO NOT crank the engine con-
tinuously for more than 10 seconds at a time. If
the engine does not start, turn the key to the
OFF position and allow a 60 second cool-down
period between starting attempts. Failure to fol-
low these guidelines can damage the starter
motor and shorten battery life.
CAUTION
Before operating the mower, read and un-
derstand all Safety Instructions and Operat-
ing Instructions.
3. After the engine starts, gradually move the
choke to the OFF position, keeping enough
choke on to allow the engine to run smoothly as
it warms up. As soon as possible, move the
choke to the OFF position.
WARNING
NEVER run the engine in an enclosed or
poorly ventilated area. Engine exhaust
contains carbon monoxide, an odorless
and deadly gas.
IMPORTANT: Make sure the choke is in the
OFF position during normal engine operation;
running with the choke in the ON position CAN
damage the engine.
ADJUSTING GROUND SPEED AND STEERING
1. Before attempting to start the engine, make
sure the operator is in the seat, the Forward
Speed Control is in NEUTRAL-PARK position,
and the blade clutch and parking brake are
DISENGAGED.
CAUTION
Learn to START, STOP, and MANEUVER
the mower in a large, open area.
NOTE: Release parking brake to prevent extra
load on the starter if the transmission neutral is
slightly out of adjustment.
If the operator has not operated a machine
with LEVER STEERING OR DUAL TRAN-
SAXLES, steering and ground operation
should be learned and practiced until the
operator is completely comfortable han-
dling the machine BEFORE ATTEMPTING
TO MOW.
CAUTION
A safety interlock switch system PRE-
VENTS CRANKING the engine with either
the Forward Speed Control or the blade
clutch (PTO) out of neutral. If the engine
cranks otherwise, the safety system is not
working and should be repaired or adjust-
ed before operating the mower. DO NOT
disconnect safety switches; they are for
the operator's protection.
DANGER
Keep feet on footrest at all times when the
machine is moving. Never operate the
tractor without a deck or implement in-
stalled.
2. Move the choke lever to the ON position and
move the throttle 1/4 to 1/2 open (toward FAST).
Turn the ignition switch to the START position to
start the engine. Release the key to RUN posi-
tion as soon as the engine starts.
NOTE: The choke may not be required if the
engine is warm.

Operating Instructions
WARNING
Beginning Recommendations are:
♦ Learn operation of the mower in an open
area away from buildings, fences, and ob-
structions. Learn operation on flat ground
BEFORE operating on slopes.
In case the transmission drive belt breaks
during operation, and if the machine is on
a slope, the machine will freewheel down
the slope. To maintain control, immedi-
ately (1) Release the steering levers and
simultaneously (2) Move the FSC to the
NEUTRAL-PARK position. When the ma-
chine is stopped or moving slowly, en-
gage the parking brake.
♦ Start maneuvering the mower with SLOW
engine speed and SLOW Forward Speed
Control setting until familiar with all operat-
ing characteristics.
♦ Remember it is not necessary to hold the
steering levers forward (a unique Walker
feature); always PULL on the levers for
steering or for reverse motion of the mower.
NOTE: This is exactly the same procedure
used to normally stop and park the machine.
NOTE: If the FSC lever will not stay in the
selected position, the friction lock needs to be
adjusted. Contact your Walker Dealer.
♦ Learn to operate the mower with your left
handonthesteeringleversandrighthandon
Forward Speed Control. The use of two
hands on the steering levers tends to cause
overcontrol.
CAUTION
♦ Learn to operate the steering levers with
smooth action. Jerky movements are hard
on the transmission and lawn. For sharp
turns, do not allow the inside wheel to stop
and twist on the grass. Pull the steering le-
ver controlling the inside wheel into reverse
for a smooth “rolling” turn (one wheel roll-
ing forward while the other rolls backward).
A safety interlock switch (seat switch) will
cause the engine to stop if the FSC is out
of the NEUTRAL-PARK position and the
operator is not in the seat. The function of
this switch should be checked by the op-
erator raising off the seat with the tractor
moving forward (allow 1 to 1-1/2 seconds
off the seat for the time delay function);
the engine should stop. If the safety sys-
tem is not working, it should be repaired
or replaced before operating the mower.
DO NOT disconnect the safety switches;
they are for the operator's protection.
♦ Practice maneuvering the mower until
you can make it go exactly where you are
aiming.
♦ Remember, for an emergency stop, or in
case of loss of control, machine movement
can always be stopped quickly by pulling
the Forward Speed Control into the NEU-
TRAL-PARK position.
2. Steer by pulling the lever on the side of desired
direction of turn, e.g., pull the LH lever to turn
left. To minimize the possibility of overcontrol,
use only one hand on both steering levers.
1. Move the FSC out of NEUTRAL-PARK position
to the desired forward speed. DO NOT hold for-
ward on steering levers. It is not necessary to
hold the FSC lever in position since a friction
lock maintains the selected lever position (and
forward travel speed).

Operating Instructions
ENGAGING THE MOWER
1. Set the engine throttle at about 1/3 speed. Do
not attempt to engage the blade clutch at
high engine speeds. This will drastically
shorten drive belt life. Use only moderate
engine speed when engaging the blade clutch.
Pull Steering
Levers with
Left Hand
2. Engage the mechanical clutch by pulling the
blade clutch lever forward quickly. DO NOT
engage slowly. For disengagement, push the
blade clutch lever backward quickly.
Forward Speed Control
(FSC)
CAUTION
A safety interlock switch (PTO switch) will
cause the engine to stop if the PTO is in
the engaged position and the operator is
not in the seat. The function of this switch
should be checked by the operator
raising off the seat with the PTO engaged
(allow 1 to 1-1/2 seconds off the seat for
the time delay function); the engine
should stop. If the safety system is not
working, it should be repaired or replaced
before operating the mower. DO NOT
disconnect the safety switches; they are
for the operator's protection.
Keep Feet on Footrest
when Moving
Correct Operator Hand Position on the Controls
3. Reverse direction of the mower by pulling both
levers backward.
NOTE: Smooth action on the steering levers
will produce smooth mower operation. Remem-
ber to keep the engine and ground speed slow
until learning the control response.
4. The FSC may be adjusted forward for faster
ground speed and backward for slower ground
speed. When mowing, ground speed should be
adjusted to match the load on the cutter blades,
i.e., as the engine pulls down in heavy cutting,
pull back on the FSC lever to reduce ground
speed. Adjusting ground speed helps maintain
a balance between engine power and blade
speed for high-quality cutting action.
IMPORTANT: DO NOT engage the blade clutch
when transporting the mower across drives, side-
walks, loose materials, etc. DO NOT engage the
blade clutch with the PTO shaft disconnected
(the mower deck removed from tractor).
5. Stop ground travel by pulling both steering
levers backward to the NEUTRAL-PARK posi-
tion (tractor not moving) and then moving the
FSC lever to the NEUTRAL-PARK position.
NOTE: If the tractor creeps forward or back-
ward with the FSC lever in the NEUTRAL-PARK
position, the transmission control needs to be
adjusted. Contact your Walker Dealer.

Operating Instructions
4. Turn the ignition switch OFF.
WARNING
Remove the key from the ignition switch
when leaving the mower unattended. This
will prevent children and inexperienced
operators from starting the engine.
5. Engage the parking brake.
IMPORTANT: The transaxles lock to prevent
the mower from rolling freely with the engine
stopped. However, if the mower is parked on a
slope, it is necessary to ENGAGE the parking
BRAKE to prevent the mower from creeping.
This is due to a small amount of slippage in the
transaxles, especially when transmission fluid
is warm.
Blade Clutch Disengaged
CAUTION
If the cutting blades strike a stationary
object while mowing, stop the mower im-
mediately, disconnect the spark plug
wires, lift the deck, and inspect the deck
and blades thoroughly for damage. Also,
make sure the blade retaining bolts are
torqued to 64 ft-lb (86.8 N·m).
FUEL SELECTOR VALVE
The tractor is equipped with dual fuel tanks. A fuel
selector valve regulates which tank is being utilized.
The valve is located on the right hand side of the
engine. The valve switches between the LH and RH
gas tanks. DO NOT run tank dry before switching
tanks.
STOPPING THE MACHINE
1. Slow the engine to idle; put the throttle in the
IDLE position.
2. Pull the steering levers to the NEUTRAL-PARK
position and then move the FSC lever backward
to the NEUTRAL-PARK position.
3. Disengage the blade clutch.
IMPORTANT: DO NOT disengage the blade
clutchwithhighenginespeed(above1/2throttle)
since the brake action on the blade drive will
cause premature wear of the Engine/PTO Belt
and internal braking mechanism (or system).
Fuel Selector Valve
WARNING
A brake stops the cutter blades from free-
wheeling within five (5) seconds after dis-
engaging the clutch. If the brake system
malfunctions and the blades do not stop
within five (5) seconds, the brake should
be repaired or replaced before operating
the mower. Contact your Walker Dealer.

TRANSAXLE LOCKOUTS
RECOMMENDATIONS FOR MOWING
IMPORTANT: DO NOT TOW this mower with the
transmission lockout engaged. Towing can produce
excessive internal pressure and damage the
transaxle(s).
IMPORTANT: Operate the engine at full speed
when mowing, to allow the engine to produce full
horsepower and to increase efficiency of the engine
cooling system.
To move the mower with the engine NOT running
(dead battery, maintenance, etc.), the transaxles are
unlocked (released).
• Keep the mower deck clean.
• Mow with sharp blades. A dull blade tears the
grass (resulting in poor lawn appearance) and uses
extra power (slowing the mowing speed).
1. Raise the body.
2. Pull up the transaxle lockout rods on both the
RH and LH transaxles and secure into place by
shouldering both rods in the chassis notch area.
• It is preferable to cut grass when it is dry and not
too tall. Mow frequently and do not cut grass too
short. (For best appearance, cut off 1/3 or less of
existing grass height.)
3. The mower will “freewheel” with the rods in the
LOCKOUT position. The levers must be in the
highest position to completely unlock the
transmissions.
• When mowing, operate the engine at or near full
throttle for the best cutting action. Mowing with a
lower engine RPM causes the mowing blade to not
cut clean and tear the grass. The engine is
designed to be operated at full speed.
• When mowing in adverse conditions (tall and/or
wet grass), mow the grass twice. Raise the mower
to the highest setting - 5 in. (127 mm) - for the first
pass and then make a second pass cutting to the
desired height.
Hydro Lockout Rod
• Use a slow setting on the FSC for trimming
operations.
Hydro Lockout Rod - Freewheel Position
4. After moving the mower, release the rods, plac-
ing them in the normal OPERATING position.
The transmission rod ends should be com-
pletely retracted against the chassis, otherwise
operation of the transmission maybe erratic.

Operating Instructions
• Make sure the mower is leveled properly for a
smooth cut. Refer to Deck Leveling in Assembly
Instructions.
Maximum Recommended
Side Slope - Do Not Operate
on Steep Slopes
• Use an alternating stripe mowing pattern for
best appearance and vary the direction of the stripe
each time the grass is mowed to avoid wear patterns
in the grass.
• Avoid damage to the grass by slipping and skid-
ding of the drive tires. Use smooth control move-
ments of the steering levers since the transaxles are
“power boosted controls” and jerking the levers can
easily slip the tires. For sharp turns, do not allow the
inside wheel to stop and twist on grass; pull inside
steering lever into reverse for a smooth “rolling” turn
(one wheel rolling forward while the other rolls back-
ward).
22 in.
20°
• The side discharge shield must not be removed
and must be kept in the lowest possible position to
deflect grass clippings and thrown objects down-
ward. Orient the side discharge away from side-
walks or streets to minimize cleanup of clippings.
When mowing close to obstacles, orient the side dis-
charge away from obstacles to reduce the chance of
damage to property by thrown objects.
60 in.
Maximum Recommended Side Slope
RECOMMENDATIONS FOR TILT-UP DECK
OPERATION/TRANSPORT
To avoid potential deck and/or tractor damage while
using the tilt-up deck, the following recommenda-
tions are offered:
Discharge
Shield
• Do not move the tractor with the deck in the tilt-
up position since both the roller wheels (on the back
of the deck) may be damaged by moving the tractor.
The tilt-up configuration should only be used when
the tractor is parked.
• The tractor body should never be tilted for-
ward with the deck in the tilt-up position. This can
cause the deck to unhook from the tractor and fall
with considerable force, potentially causing deck or
tractor damage and/or bodily injury.
Side Discharge Shield in Lowest Position
• When transporting a tractor with the deck in the
tilt-up position (on a truck or trailer), the deck
should be secured to the vehicle with a strap or
rope (stop vertical movement). This will prevent the
deck from bouncing on the rear roller wheels (caus-
ing breakage). This will also prevent the deck from
unhooking from the tractor and falling, potentially
causing deck or tractor damage. Damage to other
items parked in front of the deck may also occur.
• When operating on a slope, reduce speed and
use caution to start, stop, and maneuver. Avoid
sharp turns or sudden changes in direction. The
maximum recommended side slope operating
angle is 20 degrees or 33% grade.

KOHLER TIPS
IMPORTANT TIPS FOR CARE OF THE KOHLER
ENGINE
Air Cleaner System
• Use only Cummins/Fleetguard air cleaner
elements. Aftermarket elements may not seal in the
air cleaner housing, allowing dirt to enter the engine.
Also, aftermarket filters often skimp on the filtration
media and require more frequent replacement (see
following instructions).
Fuel System
• Fuel must be clean - free from water, dirt, and or-
ganic material.
• Change fuel filter on a regular basis and when
contamination is suspected or found in the fuel.
• Use the air flow restriction gauge to indicate the
need to service the air filter.
Starting/Stopping
• DO NOT overservice or frequently “disturb” the
air filter. A dirty air filter actually cleans better than
a new one. Changing the air filter too often can ac-
tually reduce filter efficiency and increase the oppor-
tunity for traces of dust to enter the engine. Wait
until the element really needs servicing as indicated
by the air flow restriction gauge.
• Start engine with the throttle advanced off idle
(1/4 to 1/2 throttle). This will aid starting, especially
in cold weather.
• Keep the battery fully charged.
• Match crankcase oil viscosity to the ambient tem-
perature, allowing the engine to crank faster and
start easier.
• When the air filter element is removed or re-
placed, make sure all dust is cleaned out of the air
cleaner housing and hose. Use a damp cloth and
wipe the interior of the canister and hose clean (a lit-
tle dirt left here will be sucked into the engine and
reduce engine life). When the filter is reinstalled,
make sure the element is held tight and straight in
the canister for proper seating and sealing.
• Position the throttle control between half and full
throttle, then stop the engine.
Cooling System
• Keep engine air intake screen and cylinder head
fins free of grass clippings, chaff, and dirt. Inspect
intake screen and cooling fins for cleanliness and no
damage.
• Periodically check the air intake hose for cuts,
nicks, etc., and the hose clamps for tightness.
Oil
• Periodically remove two access panels in the en-
gine shroud to inspect and clean cylinder head cool-
ing fins.
• Use only multi-viscosity oils as specified with the
viscosity matching ambient temperatures for the en-
gine operating conditions. This will aid starting in
cold weather and assure proper lubrication in hot
weather.
• Check performance of the cooling system by
starting the engine, holding a hand adjacent to the
cylinder head, and feeling the cooling airflow.
• Use only Kohler oil filters. Aftermarket filters
may not seal properly and/or have the incorrect
pressure relief valve for proper lubrication.
DANGER
Make sure to keep hands clear of exhaust
pipe, muffler, and moving parts when
checking airflow.
• Operate the engine at full speed when mowing.
This allows the engine to produce full horsepower
and move more cooling air through the engine cool-
ing fins.

Maintenance Instructions
LUBRICATION
LUBRICATION
IMPORTANT: DO NOT operate engine without
sufficient oil supply in the crankcase. DO NOT
operate with oil level below the LOW mark or
above the FULL mark on the dipstick.
WARNING
DO NOT attempt to lubricate the machine
with the engine running. Disengage the
PTO clutch, shut off the machine, and re-
move the ignition key.
Proper lubrication is an important maintenance pro-
cedure. It reduces wear and makes the machine
quieter and easier to operate.
Engine Oil
Engine Break-In Oil
No special break-in oil is required. The engine is
serviced with 10W-30, Service Class SG oil from the
factory. The oil should be changed after the initial
engine break-in period of 5-8 hours. Thereafter,
change oil after every 100 hours of operation.
Full Mark
Checking Engine Crankcase Oil Level
Low Mark
Check the engine crankcase oil level before use and
after each 8 hours of continuous operation.
Dipstick Operating Range
IMPORTANT: The importance of checking and
maintaining the proper crankcase oil level cannot be
overemphasized. Check the oil level BEFORE
EACH USE.
5. If additional oil is needed, refer to Specifications
for proper crankcase lubricant. Fill to the FULL
mark.
IMPORTANT: DO NOT overfill crankcase (oil
above FULL level) as this CAN result in
engine overheating, loss of power, and possi-
ble engine damage.
1. Park the mower on a level surface with the
engine stopped. Also, make sure the engine is
cool and oil has had time to drain into the sump
[allow at least five (5) minutes after stopping
the engine].
Changing Engine Crankcase Oil/Oil Filter
IMPORTANT: NEVER check or add oil with the
engine running.
Change the engine crankcase oil after every 100
hours of operation and the oil filter after every 200
hours of operation as follows:
2. Before removing the dipstick, clean the area
around the dipstick to keep any dirt or debris out
of the engine.
1. Park the mower on a level surface with the
engine stopped. The engine oil should be
warm before draining. If not warm from opera-
tion, start the engine and run a few minutes to
warm the oil.
3. Remove the dipstick, wipe off with a clean rag,
then reinsert the dipstick into the tube and
tighten.
2. Before removing the dipstick, clean the area
around it to keep any dirt or debris out of the
engine.
4. Remove the dipstick again and check the oil
level on the dipstick. The oil level should be
within the “Operating Range” on the dipstick
(between the LOW mark and the FULL mark).

3. Remove the dipstick and oil drain plug, and drain
oil into a suitable container. Be sure to allow
ample time for complete drainage.
7. Install the new oil filter on the engine. Turn the
oil filter clockwise until the rubber gasket con-
tacts the sealing surface, then tighten the filter
an additional 1/2 to 3/4 turn.
4. Before removing the oil filter, clean the area
around the filter to keep dirt and debris out of the
engine.
8. Reinstall the drain plug.
9. Fill the crankcase with new, clean oil. Use only
crankcase lubricants recommended by the
engine manufacturer. Refer to Specifications in
this manual or the engine owner’s manual. Use
the recommended oil viscosity for the expected
ambient temperature. Oil with the correct
viscosity will aid starting in cold weather and
assure proper lubrication in hot weather. Fill to
FULL mark on the dipstick; crankcase capacity
is 1.9 quarts (1.8 liters) when changing oil and
filter.
5. Remove the old oil filter and wipe off the filter
mounting surface on the engine.
Oil Fill/
Dipstick
IMPORTANT: Check the dipstick reading be-
fore pouring in the last 1/2 pint of oil and fill only
to the FULL mark. The oil level should never be
over the FULL mark on the dipstick; overfilling
can result in engine overheating and loss of
power.
Dipstick and Oil Fill
(view from above left side of tractor)
10. Start the engine and check for oil leaks around
the oil filter. Stop the engine, recheck the oil lev-
el, and add oil if necessary. (When the engine
is first operated with a new oil filter, the oil level
will drop slightly as the filter is filled with oil.)

LUBRICATION
Mower Deck Spindle Lubrication
Grease Fitting and Oil Point Lubrication
These spindles are permanently sealed and require
no lubrication.
Lubricate the grease fittings and oil points after
every 25 hours of operation. Lubricate more often
when operating in dusty or dirty conditions. Use
SAE general purpose lithium or molybdenum base
grease for grease fittings and light machine oil (SAE
10) to lubricate oil points. Lubricate the locations
shown in the Chassis and Deck Lubrication
Points illustration.
DSD60 Mower Deck Lubrication
Lubricate the U-Joint in the drive shaft every 8 hours
with SAE general purpose lithium or molybdenum
base grease.
Transaxle Lubrication
NOTE: PTO universal joints (on the deck and trac-
tor) require routine lubrication after every 8 hours of
running time.
• The transaxle oil lubrication is SAE 20W-50 (API
Service Class SL or higher) engine oil.
NOTE: The best way to lubricate the PTO tube half
of the universal joint assembly is to remove it from
the tractor. See instructions for removing and install-
ing PTO quick coupler, refer to Deck Installation in
Mower Deck Installation on Tractor in the Assem-
bly Instructions.
• Inspect both transaxle cases and hoses after
every 100 hours of operation for visible leaks.
• The fluid levels for each transaxle can be
checked visually by looking at the fluid levels in each
expansion reservoir. When the transaxles are cold,
the fluid level in the expansion reservoirs should be
between 1/4 and 1/2 in. (0.64 cm and 1.27 cm).

CLEANING
Transaxle Cooling Fins
IMPORTANT: In case an oil leak develops on the
input shaft, the cooling fan blowing dusty air and oil
on the transmission will quickly pack the cooling fins
with oily dirt. If this condition occurs, contact your
dealer immediately to avoid overheating and dam-
aging the transaxle.
Keeping the cooling fins on the transaxles clean and
free of obstruction is essential to avoid
overheating the transmission fluid and shortening
transmission life. The cooling fins should be
checked every 100 hours; and cleaned if
necessary.
An additional procedure in maintaining transaxle
cooling is to inspect the cooling fans. Replace the
fan(s) if blades are missing or damaged.
To clean the fins, use compressed air and/or a pres-
sure washer. The cooling fins extend all the way
around the housing -- the fins underneath need to be
clean as well as the more visible fins above. Also,
pay close attention to the area under the drive pulley.

DANGER
DANGER
BATTERIES PRODUCE EXPLOSIVE
GASES
To prevent accidental starting of the en-
gine when servicing or adjusting the ma-
chine, remove the key from the ignition
switch and disconnect the spark plug
wires.
• Charge the battery in a well-ventilated
area, so that gases produced while charg-
ing can dissipate.
Security of Air Filtration Components
• Keep sparks, flames, and smoking ma-
terials away from the battery at all times.
NOTE: The following inspection is only an external
inspection and should be done without “disturb-
ing” the filtration components.
• Makesurethebatterycap ventsareopen
(check manifold vent on each cap).
On a daily basis, visually inspect the external condi-
tion of the complete air cleaner system. The
following items should be inspected:
• Make sure the battery charger is un-
plugged before connecting or discon-
necting cables to the battery.
1. Check the Cummins/Fleetguard OptiAir™ air
cleaner canister for damage. Make sure the
cover is in place and the cover latch is secure -
do not run the engine without the air cleaner
cover in place and secure.
Check the battery charge by measuring the specific
gravity of electrolyte; if specific gravity is less than
1.225, the battery will need to be charged as follows:
• Charge the battery at 15 amps for 10 minutes.
DO NOT exceed 20 amps maximum recommended
charging rate. Charge until specific gravity is at
least 1.250. Total charging time should not exceed
one (1) hour.
2. Inspect the air intake hose for cracks, nicks,
cuts, etc., and check the hose clamps for
tightness.
3. Check to make sure the air flow indicator is in
place and tight.

IMPORTANT: Make sure battery is securely
mounted in the frame. A loose battery may cause
damage to the case resulting in acid leakage and
severe damage to the machine. A hazard may be
created by damage to critical working parts and
safety systems.
Wheel Nuts Torque
Check every 100 hours the eight (8) Drive Tire
mounting nuts. They should each be torqued to
75-85 ft-lbs. (101.7-115.2 N·m).
Cleaning the Terminals
Sharpen Mower Blades
If battery terminals are corroded, remove battery
from the mower. Using a wire brush, remove corro-
sion with a solution of one part baking soda and
four parts water. Rinse with clean water. Coat the
terminals with petroleum jelly or terminal protector
spray to retard further corrosion.
Check mower blade(s) for straightness, sharp-
ness, condition of the cutting edge, and balance
every 10 hours of operation (or more often when
mowing abrasive type grass or operating on sandy
soils). Replace blades if worn, bent, cracked, or
otherwise damaged (refer to REPLACING/
REPAIRING the Mower Blades in this section).
Use the following procedure to check and sharpen
blades:

Maintenance Instructions
CHECKING/SERVICING
NOTE: Keep blades sharp - cutting with dull
blades not only yields a poor mowing job but slows
the cutting speed of the mower and causes extra
wear on the engine and blade drive by pulling hard.
CAUTION
ALWAYS wear eye protection and gloves
when sharpening a blade.
1. Stop the engine, remove ignition key, and dis-
connect the spark plug wires before raising the
mower deck to service blades.
6. Check blade balance by positioning the blade
horizontally on a blade balancer or use a nail or
shaft through the center hole. If either end of the
blade rotates downward, grind (remove) metal
on that end until the blade will balance. The
blade is properly balanced when neither end
drops. Balance of a blade is generally main-
tained by removing an equal amount of material
from each end of the blade when sharpening.
2. Raise the deck and secure it in the tilt-up posi-
tion (refer to Deck Secured in Tilt-Up Position
photo in CLEANING of Grass Buildup in
Mower Housing in this section).
DANGER
NEVER operate cutter blades with the
deck in the raised position.

the blade tip position inside the deck housing,
and then rotating the opposite end of the blade
to the same position and comparing. If the dif-
ference in blade tip track is more than 1/8 in.
(3 mm), the blade is bent and should be re-
placed.

4. If the blade cutting edge is dull or nicked, it
should be sharpened. Remove blades for
sharpening by grasping the end of the blade
using a rag or a thick, padded glove, while loos-
ening and removing the bolt and washer that
mounts the blade.
Blade Balanced on Magnetic

5. Grind cutting edge at the same bevel as the
original. Sharpen only the top of the cutting
edge to maintain sharpness.
7. Mount the blade with wing tips pointing up into
the housing. Reinstall the blade, washer, and
bolt. Tighten the bolt to 64 ft-lb (86.8 N·m).
NOTE: Blades can be sharpened with an
electric blade sharpener, conventional electric
grinder, or a hand file.

Drive Belts
REPLACING/REPAIRING
Raise the body and inspect the condition of the four
(4) drive belts after every 25 hours of operation --
engine/PTO drive and ground drive. If the belts show
signs of cracking or deteriorating, the belts
should be replaced. Refer to REPLACING/REPAIR-
ING the Drive Belts in this section.
DANGER
To prevent accidental starting of the
engine when replacing parts or repairing
the machine, remove the key from the
ignition switch and disconnect the spark
plug wires.
Spark Plugs
Every 200 hours, remove the spark plugs, inspect,
clean, and reset the gap (or replace with a new
plug). Clean spark plug with a wire brush. If the
electrodes are burned short or pitted, replace the
plug (refer to Specifications for the proper type of
replacement plug). Check the spark plug gap with a
wire-type feeler gauge and set the gap to 0.030 in.
IMPORTANT: ALWAYS use genuine factory re-
placement parts. Substitute parts CAN result in
product malfunction and possible injury to the oper-
ator and/or others.
Drive Belts

Reinstall and tighten to 18 ft-lb
There are four (4) individual belts on the machine:
• Engine/PTO Belt [Matched Set (3)]
• Ground Drive Belt
(24.4 N·m). Both spark plugs should be replaced yearly.
Fuel Lines and Clamps
Every year, inspect the fuel lines from the tanks to
engine for deterioration or damage. Also, inspect the
fuel line clamps for tightness. Good preventive
maintenance calls for complete replacement of fuel
lines and clamps every two (2) years.
The belts may be removed and replaced using the

Check the function of the cutter blade brake by
engaging the blade clutch (PTO), operating the
engine at full throttle, then disengaging the clutch
and measuring how quickly the blades stop. Watch
the rotation of the blade drive shaft as a visual indi-
cation that movement has stopped. If the brake is
working properly, all rotation will stop five (5)
seconds after disengagement of the clutch. If the
brake system malfunctions -- blades do not stop in
five (5) seconds -- repair the brake before operating

Fuel Filter
Mower Blades
Model MBSSD is equipped with in-line fuel filters.
Visually inspect the filter periodically, and replace the
filter yearly.
Mower blades are removed and remounted as de-
scribed in the Sharpen Mower Blades instructions
(refer to CHECKING/SERVICING to Sharpen Mow-
er Blades in this section). During the course of
sharpeningandinspectingmowerblades, ifthereare
any of the following conditions of wear or dam-
age,bladesshouldbereplacedforreasonsofsafe-
ty and performance of the machine:
In-Line
Fuel Filter
• An excessive amount of the flat section of the
blade has been ground away (removed) when the
blade is sharpened. Replace the blade when less
than a 3/4 in. (19 mm) flat section remains at the
blade tip.
• Examineendsofthebladecarefully, especiallythe
intersection where the flat section of the blade turns
up to form the “wing tip” (refer to Mower Blade Pro-
file For Sharpening illustration in Sharpen Mower
Blades instructions). Since sand and abrasive ma-
terial can wear metal away in this area, the blade
should be replaced when metal thickness has
worn to 1/16 in. (1.6 mm) or less.
Fuel Filter Location
IMPORTANT: Replace the fuel filter only in a clean
area where the fuel line and connections will not be
contaminated by any dust and dirt.
DANGER
DANGER
Gasoline is extremely flammable and can
be highly explosive. To minimize danger:
When blades are operated oversandysoil,
and if blades are allowed to wear, a “slot”
may be worn into the wing tip of blade.
Eventually a piece of the blade may break
offcreatingaseriouspotentialforinjuryor
damage.
• Use only an approved fuel container for
gasoline.
• DO NOT allow open flames or sparks
near the machine while performing main-
tenance or refueling; DO NOT smoke
while working with fuel.
• Check the blades for straightness by marking
bladetippositioninsidethedeckhousingandthenro-
tating the opposite end of the blade to the same po-
sition and comparing. If the difference in blade tip
track is more than 1/8 in. (3 mm), the blade is bent
and should be replaced.
• Wipe up spilled gasoline immediately
and completely.
1. Expand and slide clamps on either side of the
filter away from filter and pull fuel lines off filter.
• Inspect the blade surface, especially in formed
areas, for cracks. Replace the blade if any cracks
are found.
2. Replace filter.
