SERVICING OF DRIVETRAIN GEARBOX
Rotary Broom
Detailed servicing and repair of the gearbox used
on the implement attachments is not covered in this
manual. Only routine maintenance and general
service instructions are provided. For the service
of the gearbox during the limited warranty period, it
is important to find a local, authorized servicing
agent of the component manufacturer. Any unau-
thorized work done on these components during
the warranty period may void the warranty. If you
have any difficulty finding an authorized outlet or
obtaining warranty service, please contact our Ser-
vice Department for assistance:
The rotary broom has a 47-inch (119 cm) sweeping
path and five-position RH/LH angle head. It is suit-
able for light snow removal, lawn dethatching/rak-
ing and general hard surface sweeping. It is raised
and lowered automatically with the lift control
switch. The rotary broom is powered by the tractor
PTO through the PTO shaft, gearbox and chain fi-
nal drive to brush drive shaft. Tire chains and a soft
cab are available as optional equipment.
Two-Stage Snowblower
The 42-inch (107 cm) two-stage snowblower
throws snow up to 40 ft (12 m). It is raised and low-
ered automatically with the lift control switch. The
blower spout is controlled with a simple position
control handle. The snowblower is powered by the
tractor PTO through the PTO shaft, snowblower
drive shaft, and gearbox. Tire chains and a soft
cab are available as optional equipment.

Debris Blower
Grafton, Wl 53024
The debris blower is used for parking lot cleaning
and leaf control. It is raised and lowered automati-
cally with the lift control switch. The directional
spout adjusts manually. The debris blower is pow-
ered by the tractor PTO through the PTO shaft.
Tire chains and a soft cab are available as optional
equipment.
UNIT DESCRIPTIONS
Implement Hitch
The implement hitch is required to mount each of
the implements to the tractor. It clips on the tractor
in place of the mower deck in less than a minute.
Each implement slides on the male hitch and easily
locks in place. The mount assembly also includes
operator footrests and an electric power lift. The lift
control switch is mounted on the FSC lever for con-
venient operator use, and is powered by the linear
actuator on the implement hitch.
IMPORTANT: These implements are not intended
for use with Model MS tractors.
Dozer Blade
The 46-inch (117 cm) dozer blade has a five-posi-
tion RH/LH angle adjustment. It is used for removal
of snow, loose dirt, and gravel, and is raised and
lowered automatically with the lift control switch.
The dozer blade is designed to “trip” forward when
striking a large object, eliminating shock to the trac-
tor and operator. Tire chains and a soft cab are
available as optional equipment.

Safety Instructions
Pay particular attention to any information labeled
DANGER, WARNING, CAUTION, IMPORTANT,
and NOTE in this manual.
Walker Manufacturing cannot predict every poten-
tially dangerous situation. Therefore, items labeled
as such in this manual do not cover all conceivable
situations. Any person using procedures, tools, or
control techniques not recommended by Walker
Manufacturing must take full responsibility for safety.

BEFORE OPERATING
WARNING
1. Read and understand the contents of this
OWNER'S MANUAL before operating the
machine. Become thoroughly familiar with all
controls and how to stop the machine and disen-
gage the controls quickly. Replacement Owner's
Manuals are available by sending the Model and
Serial Number to:
A POTENTIAL hazard that COULD result in
severe personal injury or DEATH, if warn-
ing is ignored and proper safety precau-
tions are not taken.
Walker Manufacturing Company
5925 E. Harmony Road
CAUTION
Fort Collins, CO 80528
2. Never allow children to operate or give rides
on the machine. Do not allow adults to operate
without proper instruction.
Possible hazards or unsafe practices that
MAY result in MODERATE personal injury
or property damage, or machine damage, if
warning is ignored and proper safety pre-
cautions are not taken.
3. Do not allow anyone other than the operator on
the machine.
4. Keep everyone, especially children and pets, a
safe distance away from the area being cleaned.
Do not operate with bystanders in the area.
IMPORTANT: Identifies mechanical information de-
manding special attention, since it deals with the pos-
sibility of damaging a part or parts of the machine.
5. Do not operate the machine wearing sneakers,
tennis shoes, or similar lightweight footwear.
Wear substantial protective footwear that will
improve footing on slippery surfaces.
NOTE: Identifies information worthy of special at-
tention.
6. The snow or leaves can sometimes hide objects
that might clog the snowblower or debris blower
chute, or otherwise cause damage. Clear the ar-
ea of doormats, sleds, boards, wires and other
debris.

Safety Instructions
7. Do not wear loose fitting clothing that could
get caught in moving parts. Always wear ade-
quate protective clothing including long pants.
Wearing safety glasses, safety shoes, and a
helmet is advisable and required by some local
ordinances and insurance regulations.
OPERATING
NOTE: Refer to the Walker Rider Lawnmowers
OWNER’S MANUAL for safety instructions for
operating the tractor.
1. Operate the machine only in daylight or in good
artificial light with good visibility of areas being
cleaned.
8. Prolonged exposure to loud noise can cause
impairment or loss of hearing. Operator hear-
ing protection is recommended. Wear a suit-
able hearing protective device, such as earmuffs
or earplugs.
2. Sit on the seat when starting the engine and op-
erating the machine. Keep feet on footrests at all
times when the tractor is moving and/or the im-
plement is operating.
9. Keep all protective shields and safety devic-
es in place. If a protective shield, safety device,
or decal is damaged, unusable, or missing, re-
pair or replace it before operating the machine.
3. An inexperienced operator should learn to steer
(maneuver) the tractor with a slow engine
speed before attempting any operating. Be
aware that, with the front mounted implement
configuration, the back of the machine swings to
the outside during turns.
10. Be sure any interlock switches are function-
ing correctly so the engine cannot be started
unless the Forward Speed Control lever is in
the NEUTRAL position and the PTO clutch is in
the DISENGAGED position. Also, the engine
should stop if the operator lifts off the seat with
the PTO clutch in the ENGAGED position.
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.
11. Never attempt to make any adjustments
while the engine is running, except where spe-
cifically instructed to do so.
5. Disengage the PTO clutch and put the FSC in
the NEUTRAL-PARK position before starting
the engine (an ignition interlock switch normally
prevents starting of the tractor if these controls
are in the OPERATING position).
12. Handle gasoline or diesel fuel with care.
Gasoline is highly flammable and its vapors are
explosive:
6. Do not run the engine in a confined area with-
out adequate ventilation. Exhaust fumes are
hazardous and can be deadly.
a. Use an approved fuel container.
b. Never add fuel to a running engine or hot
engine (allow hot engine to cool several
minutes).
7. Do not carry passengers - maximum seating
capacity is one (1) person.
8. Make sure the auger, brush, or debris blower is
clear of snow, ice, or debris before engaging the
PTO clutch.
c. Keep matches, cigarettes, cigars, pipes,
open flames, or sparks away from the fuel
tank and fuel container.
9. Be careful never to throw snow or blow debris to-
wards people or cars, and never allow anyone in
front of the implement.
d. Always fill the fuel tank outdoors using
care. Fill to about one inch from the top of
the tank. Use a funnel or spout to prevent
spilling.
10. Watch out for hazards hidden under snow or
leaves that could enter the chute or blower while
operating.
e. Replace the machine fuel cap and contain-
er cap securely and clean up any spilled
fuel before starting the engine.
11. 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.

Safety Instructions
12. Disengage the PTO clutch when transporting the
machine.
19. When leaving the machine unattended, disen-
gage the PTO clutch, stop the engine, and re-
move the ignition key.
13. Do not operate across the face of slopes. Use
extreme caution when changing direction on
slopes. Do not attempt to clear steep slopes.
MAINTENANCE
NOTE: Refer to the Walker Rider Lawnmowers
OWNER’S MANUAL for proper tractor mainte-
nance procedures.
14. Never adjust gauge wheels or skid shoes
with the engine running. Before adjusting
height or servicing, disengage the PTO clutch,
stop the engine, and remove the ignition key.
Wait for all movement to stop before getting off
the seat.
1. To prevent accidental starting of the engine
when servicing or adjusting the machine, re-
move the key from the ignition switch and dis-
connect the fuel solenoid wire [diesel engines] or
the spark plug wire(s) [gasoline engines].
NOTE: The PTO brake should normally stop
drive line rotation within 5 seconds of disengag-
ing the PTO clutch.
2. To reduce fire hazards, keep the engine free of
grass, leaves, excessive grease, and dirt.
3. Keep all nuts, bolts, and screws tight to ensure

the machine is in a safe, working condition.
4. Perform only maintenance instructions de-
scribed in this manual. Unauthorized mainte-
nance operations or machine modifications may
result in unsafe operating conditions.
16. If snowblower clogs:
a. Disengage the PTO clutch, stop the en-
gine, and remove the ignition key before
leaving the seat.
5. If the engine must be running to perform a main-
tenance adjustment, keep hands, feet, and
clothing away from moving parts. Do not
wear jewelry or loose clothing.
b. LOOK to make sure PTO shaft and auger
movement has stopped before trying to un-
clog the snowblower.
6. Always use proper engine service manuals
when working on the engine. Unauthorized
maintenance operations or modifications to the
engine may result in unsafe operating condi-
tions.
c. Disconnect the fuel solenoid wire [diesel
engines] or spark plug wire(s) [gasoline
engines].
d. Do not use hands or feet to unclog the
snowblower - use a stick or similar tool.
7. Altering the machine in any manner which ad-
versely affects its operation, performance, dura-
bility, or use will VOID the warranty and may
cause hazardous conditions.
17. If the implement strikes a solid object or the ma-
chine begins to vibrate abnormally, immediately
disengage the PTO clutch, stop the engine,
and wait for all moving parts to stop. Dis-
connect the fuel solenoid wire [diesel engines] or
the spark plug wire(s) [gasoline engines] to pre-
vent accidental starting. Thoroughly inspect the
implement and repair any damage before re-
starting the engine and operating the machine.
Make sure implement components are in good
condition and all bolts are tight.
8. Never attempt to disconnect any safety devices
or defeat the purpose of these safety devices.
9. Do not change the engine governor settings or
overspeed the engine. The governor has been
factory-set for maximum-safe engine operating
speed.
10. Use genuine factory replacement parts. Sub-
stitute parts may result in product malfunction
and possible injury to the operator and/or others.
18. Do not touch the engine or muffler while the
engine is running or immediately after stopping
the engine. These areas may be hot enough to
cause serious burns.
IMPORTANT: Keep all applicable manuals
immediately accessible to anyone who may

Foreign objects in snow may be thrown
farther than the snow. Use the slowest
brush speed that will perform the job.
Stay aware of the broom discharge direc-
tion at all times.

Deflector Position Control Knobs
2. To avoid snow being blown back onto the tractor
and operator, sweep with the wind blowing in
the direction of broom discharge.
Set the angle of the deflector according to the dis-
tance the snow must be thrown. To adjust the de-
flector angle, loosen the two knobs on the sides of
the deflector, slide the deflector to the required an-
gle, and securely retighten the two knobs.
Lawn Thatching and Leaf Raking
CAUTION
Optional gauge wheels must be installed
to perform these types of operation in or-
der to avoid excessive brush ground con-
tact.
Deflector Position
Control Knobs
1. Bristles should barely touch the ground for lawn
thatching, and barely touch the grass in leaf rak-
ing operations.
2. Slower brush speed and ground speed are
more adequate for lawn thatching. This will pre-
vent “bouncing” which could damage the lawn
due to excessive ground contact.
3. Minimize dust by sweeping when moisture is
high (but not wet) whenever possible.

Operating Instructions
Engaging the Snowblower
DANGER
1. Make sure that the snowblower is clear of snow
and/or ice before engaging the snowblower.
If the auger strikes a solid object or the
machine begins to vibrate abnormally, im-
mediately disengage the PTO clutch, stop
the engine, and wait for all moving parts
to stop. Disconnect the fuel solenoid wire
[diesel engines] or the spark plug wire(s)
[gasoline engines] to prevent accidental
starting. Thoroughly inspect the snow-
blower and repair any damage before re-
starting the engine and operating the
machine. Make sure auger blades are in
good condition and all bolts are tight.
2. Make sure that the auger and fan operate freely.
3. Check the oil level in the worm gearbox and if
necessary, add SAE 90 E.P. (Extreme Pres-
sure) oil. Make sure the oil level is up to the side
plug. (Refer to LUBRICATION of Two-Stage
Snowblower Gearbox in Maintenance Instruc-
tions.)
4. Check the three (3) shear bolts, one on each au-
ger section, and one between the fan and gear-
box for proper tightness, approximately 8 ft-lb
(11 N·m).
5. Adjust the snowblower so that it runs level.
6. Set the engine throttle at about 1/3 speed. DO
NOT attempt to engage the PTO clutch at
high engine speeds. This will drastically short-
en drive belt life. Use only moderate engine
speed when engaging the PTO clutch.
7. Pull the PTO clutch lever SLOWLY to engage
Engaged
Position
the snowblower.
NOTE: For cold weather operation, allow suffi-
cient time for the snowblower components (i.e.,
gearbox oil) to warm up before beginning to blow
snow.
PTO Clutch Engaged
DANGER
A safety interlock switch (seat switch) will
cause the engine to stop if the PTO clutch
is engaged and the operator is not in the
seat. The function of this switch should
be checked by the operator raising off the
seat and engaging the PTO clutch; the en-
gine should stop. If the switch is not
working, it should be repaired or replaced
before operating the snowblower. DO
NOT disconnect the safety switches; they
are for the operator’s protection.

Position
PTO Clutch Disengaged
Recommendations For Snowblowing
IMPORTANT: DO NOT engage the PTO clutch
when transporting the machine. DO NOT engage
the PTO clutch with the PTO shaft disconnected
(the snowblower removed from the tractor).
IMPORTANT: Operate the engine at full speed
when snowblowing, to allow the engine to produce
full horsepower and to increase efficiency of the en-
gine cooling system.

Operating Instructions
• When operating on a slope, reduce speed and
use caution to start, stop, and maneuver. Avoid
sharp turns or sudden changes in direction.
• When blowing through deep snow drifts, let the
snowblower work its way through the drifts. For best
results, raise the snowblower and remove a top lay-
er of snow, then pass through the area a second
time to remove the remaining snow.
• When snowblowing, operate the engine at or near
full throttle for the best snowblowing action. The
engine is designed to be operated at full speed.
• Use optional tire chains or optional all-terrain tires
to improve traction.
Throw Snow to One Side
• Disengage the PTO clutch to stop the snowblow-
er when driving the machine but not blowing snow.
Use the following pattern where snow can be thrown
to both sides. Start in the middle with the blower
spout directed to either the right or left. Drive
from one end to the other in an outward spiral,
without changing the position of the blower
spout to throw snow to both sides.
• Avoid damage to property and extra snowblowing
work by carefully choosing the direction to move
the snow. Orient the blower away from people and
property due to the possibility of thrown objects.
• To momentarily increase traction in case the drive
wheels are slipping, use the lift switch to raise the
snowblower slightly and transfer extra weight on the
drive wheels.
Removing Snow
DANGER
DO NOT blow snow with bystanders in the
area (especially children or pets).
A definite operating pattern is required to thoroughly
clean snow from an area. Each pattern described
below clears all the snow in one pass (of the pattern)
and prevents throwing snow in unwanted places.
IMPORTANT: DO NOT use the snowblower as a
dozer blade to push snow. Let the snowblower work
its way through deep snow. If the tractor is driven
forward into snow too fast, the snowblower may
become overloaded and clog.
Throw Snow to Both Sides
Clogging Checklist
Use the following pattern where snow can be thrown
only to one side. Start on the side farthest from
where the snow will be thrown. At the end of the
first pass, rotate the blower spout 180 degrees for
the return pass. At the end of each following pass,
rotate the spout 180 degrees to keep throwing snow
in the same direction.
In case of clogging, the snow throwing action will de-
crease and finally stop. When this occurs, disen-
gage the PTO clutch, stop the engine, disconnect
the fuel solenoid wire [diesel engines] or spark plug
wire(s) [gasoline engines], and remove the ignition
key. Make sure all movement has stopped be-
fore attempting to unclog.

DO NOT attempt to unclog the snowblow-
er or make any adjustments with the trac-
tor engine running. Disengage the PTO
clutch, stop the engine, and remove the
ignition key.
Chute Rotation
Handle
DANGER
Chute Rotation Handle
NEVER place hands in the blower spout.
DO NOT use hands or feet to unclog the
snowblower. Use a short stick or similar
tool to remove any clogged material.
Deflector Position Control Knob
Set the angle of the deflector according to the dis-
tance the debris must be thrown. To adjust the de-
flector angle, loosen the knob on the RH side of the
deflector, slide the deflector to the required angle,
and securely retighten the knob.
The following list of items should be checked if a pat-
tern of clogging begins to develop. All of these items
are capable of causing clogging.
• Check that the inside of the snowblower housing
is clean and free of snow and/or ice buildup.
• Check that the auger is in good condition and not
bent, both the auger flighting and the center pad-
dles.
• Check the inside of the blower spout for smooth-
ness and freedom of obstruction.
Remember, anything that restricts airflow or materi-
al flow along the entire path from the auger to the
blower spout can cause clogging.

property due to the possibility of thrown objects.
Engaging the Debris Blower
1. Set the engine throttle at about 1/3 speed. DO
NOT attempt to engage the PTO clutch at
high engine speeds. This will drastically short-
en drive belt life. Use only moderate engine
speed when engaging the PTO clutch.
• To momentarily increase traction in case the drive
wheels are slipping, use the lift switch to raise the
debris blower slightly and transfer extra weight on
the drive wheels.
STOPPING THE MACHINE
2. Pull the PTO clutch lever SLOWLY to engage
the debris blower.
1. Slow the engine to idle; put the throttle in the
IDLE position.
NOTE: For cold weather operation, allow suffi-
cient time for the debris blower components to
warm up before beginning to blow debris.
2. Pull the steering levers to the NEUTRAL posi-
tion and then move the FSC lever backward to
the NEUTRAL-PARK position.
WARNING
3. Disengage the PTO clutch.
IMPORTANT: DO NOT disengage the PTO
clutch with high engine speed (above 1/2 throt-
tle) since the brake action on the PTO drive will
cause premature wear of the brake band.
A safety interlock switch (seat switch) will
cause the engine to stop if the PTO clutch
is engaged and the operator is not in the
seat. The function of this switch should
be checked by the operator raising off the
seat and engaging the PTO clutch; the en-
gine should stop. If the switch is not
working, it should be repaired or replaced
before operating the debris blower. DO
NOT disconnect the safety switches; they
are for the operator’s protection.
WARNING
A brake stops the machine from free-
wheeling within five (5) seconds after dis-
engaging the PTO clutch. If the brake
system malfunctions and the machine
does not stop within five (5) seconds, the
brake should be adjusted or repaired be-
fore operating the machine. Refer to the
appropriate Tractor Owner’s Manual for
adjustment procedures.
IMPORTANT: DO NOT engage the PTO
clutch when transporting the machine. DO NOT
engage the PTO clutch with the PTO shaft
disconnected (the debris blower removed from
the tractor).
4. Turn the ignition switch OFF.
Recommendations For Operating the Debris
Blower
WARNING
IMPORTANT: Operate the engine at full speed
when operating the debris blower, to allow the en-
gine to produce full horsepower and to increase ef-
ficiency of the engine cooling system.
Remove the key from the ignition switch
when leaving the machine unattended.
This will prevent children and inexperi-
enced operators from starting the engine.
• When operating on a slope, reduce speed and
use caution to start, stop, and maneuver. Avoid
sharp turns or sudden changes in direction.
5. Engage the parking brake.
IMPORTANT: The hydrostatic transmissions
lock to prevent the machine from rolling freely
with the engine stopped. However, if the ma-
chine is parked on a slope, it is necessary to
ENGAGE the parking BRAKE to prevent the
machine from creeping. This is due to a small
amount of slippage in the hydrostatic transmis-
sions, especially when transmission fluid is
warm.
• Use optional tire chains or optional all-terrain tires
to improve traction.
• Disengage the PTO clutch to stop the debris
blower when driving the machine but not operating
the debris blower.
• Avoid damage to property and extra cleaning
work by carefully choosing the direction to move
