Trip Spring
The dozer blade was designed to “trip” forward when striking large rocks, tree stumps, etc. Once the blade clears the obstacle, the blade will spring back to the normal operating position, eliminating the shock to the operator and tractor. Adjust the trip spring tension by raising and lowering the eyebolt and retightening the nut to the amount of tension required for safe operation. [Normally about 1/2 in.
(13 mm) of thread should protrude beyond the nut.]

CAUTION
DO NOT strike large objects with the dozer blade during rigid blade operation.
Speed Recommendations
For maximum power, set the engine speed control in
FAST (full power) position. Use the forward speed control arm to control the ground speed best suited for the job being done. Use faster speeds for lighter snow removal, and slower speeds for heavier snow removal.
ROTARY BROOM CONTROLS
Ground Contact Knob
Turning the ground contact knob clockwise de-
creases brush ground contact pressure. Turning the knob counterclockwise increases brush ground contact pressure. Once the knob is adjusted, it should only be used to compensate for brush wear.
IMPORTANT: Adjust the brush to ground contact pressure so that the broom head, when lifted by the front, weighs approximately 30 to 50 lb (14 to 23 kg).
More weight than this may cause premature brush wear and overheating of the gearbox.

ROTARY BROOM OPERATION
CAUTION
Before operating the rotary broom, read and understand all Safety Instructions and
Operating Instructions.
Raising and Lowering the Broom
Refer to Implement Lift Switch in this section.
Engaging the Rotary Broom
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 shorten drive belt life. Use only moderate engine
speed when engaging the PTO clutch.
2.
Pull the PTO clutch lever SLOWLY to engage the rotary broom.
NOTE: For cold weather operation, allow sufficient time for the rotary broom components (i.e., gearbox oil) to warm up before beginning to operate.
CAUTION
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 engine should stop. If the switch is not working, it should be repaired or replaced before operating the rotary broom. DO
NOT disconnect the safety switches; they are for the operator’s protection.
IMPORTANT: DO NOT engage the PTO clutch when transporting the machine. DO NOT en- gage the PTO clutch with the PTO shaft dis-
connected (the rotary broom removed from the tractor).
General Sweeping
1.
Minimize dust by reducing brush speed and by sweeping on days with high moisture.
2.
For light material, angle the broom 12.5 de-
grees right or left, rather than the fully angled
25 degrees, to obtain a wider sweeping path.
3.
Prevent damage to the broom by removing large foreign objects from the sweeping area prior to operation.
IMPORTANT: For efficient operation, sweep with the tips of the bristles like a broom; not with the sides of the bristles like a mop.
37
38
Operating Instructions
Snow Removal
WARNING
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 direction at all times.
1.
The rotary broom works best on snow depths of
4 in. (10 cm) or less. Larger amounts of snow can be moved if the ground speed is reduced.
2.
To avoid snow being blown back onto the tractor and operator, sweep with the wind blowing in the direction of broom discharge.
Lawn Thatching and Leaf Raking
CAUTION
Optional gauge wheels must be installed to perform these types of operation in order to avoid excessive brush ground contact.
1.
Bristles should barely touch the ground for lawn thatching, and barely touch the grass in leaf raking operations.
2.
Slower brush speed and ground speed are more adequate for lawn thatching. This will prevent “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.
TWO-STAGE SNOWBLOWER CONTROLS
Chute Rotation Handle
The chute rotation handle is located on the rear of the snowblower head, on the lower RH side of the discharge chute. The chute rotates in a 228 degree arc, by cranking the rotation handle. Turning the handle clockwise rotates the chute clockwise.
Turning the handle counterclockwise rotates the chute counterclockwise.

Operating Instructions
Engaging the Snowblower
1.
Make sure that the snowblower is clear of snow and/or ice before engaging the snowblower.
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 Pressure) oil. Make sure the oil level is up to the side plug. (Refer to LUBRICATION of Two-Stage
Snowblower Gearbox in Maintenance Instructions.
)
4.
Check the three (3) shear bolts, one on each auger section, and one between the fan and gearbox 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 shorten drive belt life. Use only moderate engine
speed when engaging the PTO clutch.
7.
Pull the PTO clutch lever SLOWLY to engage the snowblower.
NOTE: For cold weather operation, allow sufficient time for the snowblower components (i.e., gearbox oil) to warm up before beginning to blow snow.
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 engine 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.
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).
DANGER
If the auger strikes a solid object or the machine begins to vibrate abnormally, immediately 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 snowblower and repair any damage before restarting the engine and operating the machine. Make sure auger blades are in good condition and all bolts are tight.

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 layer 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.
•
Disengage the PTO clutch to stop the snowblower when driving the machine but not blowing snow.
•
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.
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.
Throw Snow to One Side
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.
Throw Snow to Both Sides
Clogging Checklist
In case of clogging, the snow throwing action will decrease and finally stop. When this occurs, disengage 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.
Operating Instructions
DANGER
DO NOT attempt to unclog the snowblower or make any adjustments with the tractor engine running. Disengage the PTO clutch, stop the engine, and remove the ignition key.
Chute Rotation
Handle
DANGER
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.
The following list of items should be checked if a pattern 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 paddles.
•
Check the inside of the blower spout for smooth- ness and freedom of obstruction.
Remember, anything that restricts airflow or material flow along the entire path from the auger to the blower spout can cause clogging.
DEBRIS BLOWER CONTROLS
Chute Rotation Handle
The chute rotation handle is located on the rear of the debris blower, on the upper RH side of the impeller housing. The chute rotates in a 230 degree arc, by cranking the rotation handle. Turning the handle clockwise rotates the chute clockwise.
Turning the handle counterclockwise rotates the chute counterclockwise.

STOPPING THE MACHINE
1.
Slow the engine to idle; put the throttle in the
IDLE position.
2.
Pull the steering levers to the NEUTRAL position and then move the FSC lever backward to the NEUTRAL-PARK position.
3.
Disengage the PTO clutch.
IMPORTANT: DO NOT disengage the PTO clutch with high engine speed (above 1/2 throttle) since the brake action on the PTO drive will cause premature wear of the brake band.
WARNING
A brake stops the machine from freewheeling within five (5) seconds after disengaging 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 before operating the machine. Refer to the appropriate Tractor Owner’s Manual for adjustment procedures.
4.
Turn the ignition switch OFF.
WARNING
Remove the key from the ignition switch when leaving the machine unattended.
This will prevent children and inexperienced operators from starting the engine.
5.
Engage the parking brake.
IMPORTANT: The hydrostatic transmissions lock to prevent the machine from rolling freely with the engine stopped. However, if the machine 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 transmissions, especially when transmission fluid is warm.
