guard (deflector) in place.
Also, do not allow anyone in the area while the unit is runnin
someone does enter the area, shut the unit off immediatuntil they
leave.
Moving Parts
This equipment has many moving parts that can injure
you or someone else. However, if you stay in the
operator zone (area behind the handles and controls),
and follow the safety rules in this operator’s manual, the
unit is safe to operate.
The mower deck has spinning mower blades that can
amputate hands and feet. Do not allow anyone near the
unit while it is running! Keep safety devices (guards,
shields, and switches) in place and working.
To help you, the operator, use this equipment safely, it
is equipped with an operator-present safety system. Do
NOT attempt to alter or bypass the system. See your

the Troubleshooting, Adjustments & Repair section.
1. Engage the parking brake. Make sure the PTO
switch is disengaged and the motion control lever
is in the NEUTRAL position.
2. Start the engine (see STARTING THE ENGINE).
3. Set the throttle to FULL.
4. Engage the PTO by pulling up on the PTO switch.
5. Begin mowing.
6. When finished, shut off the PTO.
7. Stop the engine (see
STOPPING THE TRACTOR AND ENGINE).
Tall Grass Requires Incremental Cutting
MOWING RECOMMENDATIONS
For extremely tall grass, set the cutting height at
maximum for the first pass, and then reset it to the
desired height and mow a second or third time.
Several factors can affect how well your machine cuts
grass, Following proper mowing recommendations
can improve the performance and life of your
machine.
Don’t cover the grass surface with a heavy layer of
clippings. Consider using a grass collection system
d starting a compile.
Height of Grass
Often cutting height is a matter of personal
preference. Typically, you should mow the grass
when it is is between three and five inches high.
The proper cutting height range for a specific lawn
will depend upon several factors, including the
type of grass, the amount of rainfall, the prevailing
temperature, and the lawn’s overall condition.
Cut Here On
Cut
First Pass
Here On
Second
Pass
Cutting the grass too short causes weak, thin grass
plants, which are easily damaged by dry periods and
pests. Cutting too short is often more damaging than
allowing the grass to be slightly higher.
Letting grass grow a bit longer—especially wn it
is hot and dry—reduces heat build-up, preseves
needed moisture and protects the grom heat
damage and other problems. Howeveallowing grass
to grow too high can cause thin turf and additional
problems.
Cutting off too much at one time shocks the plant’s
growth system and weakens the grass plants. A
good rule of thumb is the 1/3 rule: to cut no more
than one third of the grass height, and never
more than 1 inch at a time.
The amount of grass you are able to cut in one pass
is also effected by the type of mowing system you are
using (for example, broadcasting with side discharge
decks can process a much larger volume of grass
than mulching does).

Operation
When and How Often to Mow
The time of day and condition of the grass greatly
affect the results you’ll get when mowing. For the best
results, follow these guidelines:
1. Mow when the grass is between three and five
inches high.
2. Mow with sharp blades. Short clippings of grass
one inch or shorter decompose more quickly than
longer blades. Sharp mower blades cut grass
cleanly and efficiently, preventing frayed edges
which harm the grass.
Where possible, make one or two passes around the
outside of the area discharging the grass INTO the
lawn to keep the cut grass off fences and walks.
3. Mow at time of day when the grass is cool and
dry. Late afternoon or early evening often provide
these ideal mowing conditions.
4. Avoid mowing after rain or even heavy dew, and
never mulch when the grass is wet (moist grass
does not mulch well, and clumps beneath the
mower deck).
Mowing Patterns
Always start mowing on a smooth, level area.
The size and type of area to be mowed will determine
the best mowing pattern to use. Obstructions such as
trees, fences and buildings, and conditions such as
slopes and grades must also be considered.
remainder of thowing should be done in the
opposite directon so that the clippings are dispersed
OUT onto the area of lawn previously cut.
1. Cut long straight strips overlapping slightly.
MOWING METHODS
2. Where possible, change patterns occasionally
to eliminate matting, graining or a corrugated
appearance.
Prer Broadcast Mowing
oadcasting, or side-discharging, disperses fine
clippings evenly over the entire lawn. Many golf
courses use this method. Your mower has a deep
dish deck to allow freer circulation of clippings so they
are broadcast evenly over the lawn.
3. For a truly professional cut, mow across the lawn
in one direction, then recut the lawn by mowing
perpendicular to the previous cut.
Note: Always operate the engine at full thtle
when mowing.
ENGINE SPEED & GROUND SPEED FOR
BROADCASTING
If you hear the engine slowing down, u are mowing
too fast—using a slower ground speed will improve
the cutting efficiency of the blades and prevents many
common cutting problems. Use an appropriate ground
speed for the thickness and height of the grass
you are cutting (3rd gear or slower for manual gear
models). If you hear the engine slowing down you are
mowing too fast, use a slower ground speed.
Always operate the engine at full throttle when
mowing. If you hear the engine slowing down, you
are mowing too fast—using a slower ground speed
will improve the cutting efficiency of the blades and
prevents many common cutting problems.
ALWAYS use an appropriate ground speed for the
thickness and height of the grass you are cutting (3rd
gear or slower for manual gear models). If you hear
the engine slowing down you are mowing too fast,
use a slower ground speed.
HOW MUCH GRASS TO CUT OFF WHEN
BROADCASTING
Mow when the grass is 3-5 inches long. Do not cut
the grass shorter than 2 to 2-1/2 inches. Do not cut
off more that 1 inch of grass in a single pass

Operation
Proper Mulching
PUSHING THE MOWER BY HAND
Mulching consists of a mower deck which cuts and
recuts clippings into tiny particles and which then
blows them down INTO the lawn. These tiny particles
decompose rapidly into by-products your lawn can
use. UNDER PROPER CONDITIONS, your mulching
mower will virtually eliminate noticeable clippings on
the lawn surface.
DO NOT TOW MACHINE
Towing the machine will cause hydraulic
transaxle damage. Do not use another
vehicle to push or pull this unit.
1. Disengage the PTO, engage the parking brake,
turn the ignition OFF, and remove the key.
NOTE: When mulching under heavy cutting
conditions, a rumbling sound may be present and is
normal.
2. To disengage the transmissions (free-wheel
position), lift the hydraulic release levers (A,
Figure 9) located in front of the gas tank. Lock
into position shown in Figure 9.
MULCHING REQUIRES EXCELLENT MOWING
CONDITIONS
Mulching mowers cannot function properly if the grass
is wet, or if the grass is simply to high to cut. Even
more than normal mowing, mulching requires that the
grass be dry and the the appropriate amount is cut.
3. Disengage the parking brake.
The mower can now be pushed by hand.
4. After moving the mower, re-engage the
transmissions (drive position) by unlocking
the levers and returning them to the down
position. If the levers are not completely down,
a partial by-pass may potentially damage the
ransmissions.
Do not use the mower as a mulching mower during
the first two or three mowings in the spring. The
long grass blades, quick growth, and often wetter
conditions are more suitable for broadcasting (side-
discharging) or grass bagging operation.
ENGINE SPEED & GROUND SPEED FOR
BROADCASTING
Use full engine throttle matched with a slow ground
speed so that clippings will be finely cut. Ground
speed while mulching should be HALF of the
speed that would be used when broadcasting (side
discharging) under similar conditions. Since mulching
requires more horsepower than broadcasting, using
a slower ground speed is vitally important for proper
mulching operation.
A
HOW MUCH GRASS TO MULCH
The best mulching action typically results frocutting
only the top 1/2 inch to 3/4 inch of grablade. This
provides short clippings which decose properly
(much more quickly than longer clippings). The ideal
cutting height will vary with climate, time of year,
and quality of your lawn. We recommend that you
experiment with both the cutting height and ground
speed until you achieve the best cut. Start with a high
cutting height and using progressively lower settings
until you find a cutting height that is matched to your
mowing conditions and preferences.

Troubleshooting, Adjustment & Repair
TROUBLESHOOTING
WARNING
While normal care and regular maintenance will
extend the life of your equipment, prolonged or
constant use may eventually require that service be
performed to allow it to continue operating properly.
To avoid serious injury, perform maintenance
on the mower only when the engine is stopped
and the parking brake engaged.
The troubleshooting guide below lists the most
common problems, their causes and remedies.
Always remove the ignition key, disconnect
the spark plug wire and fasten it away from
the plug before beginning the maintenance, to
prevent accidental starting of the engine.
See the information on the following pages for
instructions on how to perform most of these minor
adjustments and service repairs yourself. If you

TRANSMISSION MAINTENANCE
The hydrostatic transmissions are sealed units that
require no maintenance other than the following.
A
• Keep the machine and the transmission cooling
fins clear or grass, leaves and debris.
• Keep oil level in the reservoir (A, Figure 32) at the
“FULL” line (B). Extra oil in the reservoir will not
benefit the machine.
B
• If it is necessary to add oil to the reservoir, use
SAE straight 20 or 30 weight motor oil. DO NOT
use a multi-grade oils. Make sure the area
around the oil reservoir is free from dust, dirt and
debris before opening the reservoir.
• Make sure the oil reservoir cap are tight.
Figure 32. Oil Reservoirs

2. Place a drain pan under each transmission a
remove the filters to drain the oil. See Figure 3.
NOTE: Before removing the right hanransmission
filter the filter guard must be remove
3. Once oil has drained from transmissions, replace
with new filters (P/N 5021068X1), placing a light
film on the seal of the filter before installing.
Hand-tighten filter only.
3. Start the engine and adjust throttle control to just
above idle. See the STARTING THE ENGINE
section for proper starting instructions.
4. Fill oil reservoirs 3/4 full with SAE straight 20 or 30
weight motor oil.
4. Run engine for 5 minutes. Watch the oil level
in the reservoirs. Add oil to the “FULL” line (B,
Figure 32) as necessary.
To Bleed Air From Transmissions
1. Locate the machine in a secure area, away from
bystanders and preferably facing a wall. Raise
the drive tires off the ground and secure with jack
stands.
5. With engine running, cycle controls forward and
reverse until positive response to the drive is
achieved. Do not attempt to move the unit until
bleeding is complete or serious damage may
occur.
2. Continue to fill reservoirs to the FULL LINE until
the oil level stops going down.
6. Watch oil levels for the next few days and add oil
to the reservoirs as necessary.

Troubleshooting, Adjustment & Repair
6. Charge the battery until fully charged (until the
specific gravity of the electrolyte is 1.250 or higher
and the electrolyte temperature is at least 60° F).
The best method of making certain a battery is
fully charged, but not over charged, is to measure
the specific gravity of a cell once per hour. The
battery is fully charged when the cells are gassing
freely at low charging rate and less than 0.003
change in specific gravity occurs over a three hour
period.
BATTERY SERVICE
WARNING
Keep open flames and sparks away from the
battery; the gasses coming from it are highly
explosive. Ventilate the battery well during
charging.
Checking Battery Voltage
Jump Starting With Auxiliary (Booster)
Battery
Jump starting is not recommended. However, if it
must be done, follow these directions. Both booster
and dis-charged batteries should be treated carefully
when using jumper cables. Follow the steps below
EXACTLY, being careful not to cause sparks. Refer
to Figure 34.
A voltmeter can be used to determine condition of
battery. When engine is off, the voltmeter shows
battery voltage, which should be 12 volts. When
engine is running, the voltmeter shows voltage of
charging circuit which normally is 13 to 14 volts.
A dead battery or one too weak to start the engine
may not mean the battery needs to be replaced.
For example, it may mean that the alternator is not
charging the battery properly. If there is any doubt
about the cause of the problem, see your dealer. If
you need to replace the battery, follow the steps
under Cleaning the Battery & Cables in the Regular
Section.
1. Both batteries must be of the same voltage.
2. Position the vehicle with the booster battery
adjacent to the vehile with the discharged battery
so that booster cbles can be connected easily
o the batteries th vehicles. Make certain
vehicles do not touch each other.
Charging a Completely Discharged
Battery
1. Be aware of all the safety precautions you ld
observe during the charging operation. If you are
unfamiliar with the use of a battery charger and
hydrometer, have the battery serviced by your
dealer.
3. Wear safety glasses and shield eyes and face
from batteries at all times. Be sure vent caps are
tight. Place damp cloth over vent caps on both
atteries.
4. nnect positive (+) cable to positive post of
discharged battery (wired to starter or solenoid).
5. Connect the other end of same cable to same
post marked positive (+) on booster battery.
2. Add distilled water sufficient to cover the plate (fill
to the proper level near the end of the charge
If the battery is extremely cold, allow it to arm
before adding water because the water lvel will
rise as it warms. Also, an extremold battery
will not accept a normal charge untit becomes
warm.
6. Connect the second cable negative (-) to other
post of booster battery.
7. Make final connection on engine block of stalled
vehicle away from battery. Do not lean over
batteries.
3. Always unplug or turn the charger off before
attaching or removing the clamp connections.
8. Start the engine of the vehicle with the booster
battery. Wait a few minutes, then attempt to start
the engine of the vehicle with the discharged
battery.
4. Carefully attach the clamps to the battery in
proper polarity (usually red to [+] positive and
black to [-] negative).
9. If the vehicle does not start after cranking for thirty
seconds, STOP PROCEDURE. More than thirty
seconds seldom starts the engine unless some
mechanical adjustment is made.
5. While charging, periodically measure the
temperature of the electrolyte. If the temperature
exceeds 125° F (51.6° C), or if violent gassing or
spewing of electrolyte occurs, the charging rate
must be reduced or temporarily halted to prevent
battery damage.

Troubleshooting, Adjustment & Repair
10. After starting, allow the engine to return to idle
speed. Remove the cable connection at the
engine or frame. Then remove the other end of
the same cable from the booster battery.
11. Remove the other cable by disconnecting at the
discharged battery first and then disconnect the
opposite end from the booster battery.
12. Discard the damp cloths that were placed over the
battery vent caps.

WARNING
WARNING
Any procedure other than the preceding could
result in:
For your personal safety, use extreme care
when jump starting. Never expose battery to
open flame or electric spark – battery action
generates hydrogen gas which is flammable
and explosive. Do not allow battery acid to
contact skin, eyes, fabrics, or painted surfaces.
Batteries contain a sulfuric acid solution which
can cause serious personal injury or property
damage.
(1) personal injury caused by electrolyte
squirting out the battery vents,
(2) personal injury or property damage due
to battery explosion,
(3) damage to the charging system of the
booster vehicle or of the immobilized
vehicle.
Do not attempt to jump start a vehicle having a
frozen battery because the battery may rupture
or explode. If a frozen battery is suspected,
examine all fill vents on the battery. If ice
can be seen or if the electrolyte fluid cannot
be seen, do not attempt to start with jumper
cables as long as the battery remains frozen.
When removing or installing battery cables,
disconnect the negative cable FIRST and
reconnect it LAST. If not done in this order, the
positive terminal can be shorted to the frame
by a tool.
To avoid engine damage, do not disconnect
battery while engine is running. Be sure
terminal connections are tight before starting.

not be liable to warrant failures of warranted parts caused by the use of a non
exempted add on or modified part.
d. Catalyst System
Catalytic converter
Exhaust manifold
Air injection system or pulse valve
3. Consequential Coverage
e. Miscellaneous Items Used in Above Systems
Vacuum, temperature, position, time sensitive valves and hes
Connectors and assemblies
Coverage shall extend to the failure of any engine components caused by the
failure of any warranted emissions parts.
2. Length of Coverage
4. Claims and Coverage Exclusions
For a period of two years from date of original purchase, Barrants to the original
purchaser and each subsequent purchaser that the engine is designed, built, and
equipped so as to conform with all applicable regulations adopted by the Air
Resources Board; that it is free from defects in material and workmanship that could
cause the failure of a warranted part; and that it is identical in all material respects to
the engine described in the manufacturer’s application for certification. The warranty
period begins on the date the engine is originally purchased.
Warranty claims shall be filed according to the provisions of the B&S engine
warranty policy. Warranty coverage does not apply to failures of emissions parts
that are not original equipment B&S parts or to parts that fail due to abuse, neglect,
or improper maintenance as set forth in the B&S engine warranty policy. B&S is not
liable for warranty coverage of failures of emissions parts caused by the use of
add-on or modified parts.
Look For Relevant Emissions Durability Period and Air Index Information
On Your Small Off-Road Engine Emissions Label
Engines that are certified to meet the California Air Resources Board (CARB) small
Briggs & Stratton engines are certified to meet the United States Environmental
Protection Agency (USEPA) Phase 2 or Phase 3 emissions standards. The Emissions
Compliance Period referred to on the Emissions Compliance label indicates the number
of operating hours for which the engine has been shown to meet Federal emissions
requirements.
off-road Emissions Standard must display information regarding the Emissions Durability
Period and the Air Index. Briggs & Stratton makes this information available to the
consumer on our emissions labels. The engine emissions label will indicate certification
information.
The Emissions Durability Period describes the number of hours of actual running time
for which the engine is certified to be emissions compliant, assuming proper
maintenance in accordance with the Operating & Maintenance Instructions. The
following categories are used:
For engines less than 225 cc displacement.
Category C = 125 hours, Category B = 250 hours, Category A = 500 hours
Moderate:
For engines of 225 cc or more displacement.
Category C = 250 hours, Category B = 500 hours, Category A = 1000 hours
Engine is certified to be emissions compliant for 125 hours of actual engine running time.
Intermediate:
Engine is certified to be emissions compliant for 250 hours of actual engine running time.
Extended:
Engine is certified to be emissions compliant for 500 hours of actual engine running time.
For example, a typical walk-behind lawn mower is used 20 to 25 hours per year.
Therefore, the Emissions Durability Period of an engine with an intermediate rating
would equate to 10 to 12 years.
