OPERATION

WARNING: Before operating the snowblower, become familiar with the location and function of all operator controls. Knowing the location, function, and operation of these controls is important for safe and efficient operation of the snowblower.

Tractor Controls

Refer to the appropriate Tractor Owner’s

Manual for complete information about tractor operating controls.

Lift Handle

The lift handle is located to the right of the operator at the back of the snowblower right footrest. The lift handle is used to raise and lower the snowblower. Moving the handle forward lowers the snowblower; moving it backward raises the snowblower.

Foot Trigger

The foot trigger is located on the right footrest.

The foot trigger and lift handle are used together to lower the snowblower. Pull the lift handle back, press the foot trigger, and hold on to the lift handle while letting it move forward to lower the snowblower.

IMPORTANT: To avoid the snowblower dropping down with force, DO NOT release the lift handle while depressing the foot trigger or before the snowblower has reached the ground.

Rotation Handle

The crank is located to the left of the operator at the back of the snowblower. Turn the crank clockwise and the chute will turn counter clockwise.

Deflector Positions

The knob is located to the right of the operator at the right side of the chute of the snowblower. Loosen the knob and adjust the deflector at the desired position, then tighten the knob securely.

Sliding the deflector higher throws snow higher and farther. Sliding the deflector down throws snow lower, and closer.

OM 0352SB-A 17

CAUTION: ALWAYS disengage the

PTO clutch and plut the Forward Speed

Control (FSC) in the NEUTRAL-PARK

position before starting the engine.

NOTE: For cold weather operation, follow the proper operating procedures in the appropriate

Tractor Owner’s Manual. Allow sufficient time for the tractor engine to warm up before engaging the snowblower.

Engaging The Snowblower

CAUTION: Before operating the snowblower, read and understand all

Safety Instructions and Operating

Instruction.

1. Set the engine throttle at about 1/3 speed.

DO NOT attempt to engage the PTO clutch at high engine speed. This will drastically shorten drive belt life. Use only moderate engine speed when engaging the PTO clutch.

2. Pull the PTO clutch lever SLOWLY engage the snowblower.

NOTE: For cold weather operation, allow sufficient time for the snowblower component

(i.e., gearbox grease) to warm up before beginning to blow snow.

CAUTION: A safety interlock switch

(seat switch) will cause the engine to stop if the PTO clutch is engaged and the tractor operator is not on 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).

CAUTION: 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 park 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.

Stopping The Snowblower

1. Slow the engine to idle; put the throttle in the IDLE position.

2. Pull the steering lever to the NEUTRAL position and move the Forward Speed

Control (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"

(13mm) throttle) since the brake action of the PTO drive will cause premature wear of the brake band.

WARNING: A brake stops the auger from freewheeling within five seconds after disengaging the PTO clutch. If the brake system malfunctions and the auger does not stop within five seconds, the brake should be adjusted or repaired before operating the snowblower. Refer to the appropriate Tractor Owner’s Manual for

adjustment procedures.

4. Turn the ignition switch OFF

5. Engage the parking brake.

OPERATION

IMPORTANT: The hydrostatic transmissions lock prevents 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 creeping. This is due to a small amount of slippage in the hydrostatic transmission, especially when the transmission fluid is warm.

Recommendation For Snowblowing

IMPORTANT: Operate the engine at full speed when snowblowing, to allow the engine to produce full horse power and increase efficiency of the engine cooling

system.

1. When blowing through deep snowdrifts, let the snowblower work its way through the drifts. For best results, raise the snowblower skid shoes and remove a top layer of snow, then lower the skid shoes and pass through the area a second time to remove the remaining snow.

2. When snowblowing, operate the engine at or near FULL THROTTLE for the best snowblowing action. The engine is designed to operate at full speed.

3. Use optional tire chains or optional allterrain tires to improve traction.

4. Disengage the PTO clutch to stop the snowblower when driving the machine but not blowing snow.

5. Avoid damage to property and extra snowblowing work by carefully choosing the direction to move the snow. Orient the chute away from people and property due to possibility of thrown objects.

6. To momentarily increase traction in case the drive wheels are slipping, use the lift handle to raise the snowblower slightly and transfer extra weight on the drive wheels.

WARNING: Remove the key from the ignition switch when leaving the machine unattended. This will prevent children and inexperienced operators from starting the engine.

OPERATION

A

DJUSTMENTS

ATTENTION

: To avoid personal injury, be sure the tractor engine is off, the drive shaft disengaged, and all movement has stopped before making any adjustments.

Deflector Adjustment

Set the angle of deflection according to the distance the snow must be thrown. To set the deflector angle:

• Loosen the deflector knob located on the side of the deflector; adjust the deflector to the appropriate angle.

• Retighten the knobs.

Skid Shoe Adjustment

(Figure 14)

Adjust the snowblower so that the skid shoes run level and according to the surface conditions so that stones are not thrown with the snow. Adjust both skid shoes to the same height to keep the cutting edge level and adjust upwards for smooth surfaces.

Loosen skid shoe bolts and adjust according to instructions below, and securely tighten bolts:

Clearance between cutting edge and

surface:

• Level paved surface : A djust to 1/16" to 1/8"

(1.5 mm to 3 mm)

• Uneven or gravel surface: Adjust to 1/2" to 5/8"

(13 mm to 16 mm)

Sprocket Alignment

(Figure 15)

To check the alignment of the two sprockets lean a ruler or straight bar (item 1) against the sprocket (item 3). Unscrew the 5/16"NC setscrews of the sprocket (item 2) and lean it against the ruler or straight bar (item 1).

WARNING: If the sprockets alignment is not done carefully the chain may be broken or released from the two gears and can cause important damages to the snowblower and serious personal injury.

OPERATION

S

NOW REMOVAL METHODS

When removing snow, do not use the snowblower as a dozer blade to push snow. Let the snowblower work its way through deep drifts. If the speed of your tractor is too fast, the snowblower may become overloaded and clog. For best results, raise the snowblower and remove a top layer of snow. A second pass with the snowblower will remove the remaining snow.

IMPORTANT: Use full engine RPM power when removing wet, sticky snow. Low engine RPM power will tend to clog the chute.

WARNING

To avoid serious personal injury:

Do not use hands or feet to unclog chute. Do not attempt to clear clogged chute of snow while tractor engine is running. If the chute clogs, disengage the PTO shaft, shut off the engine, set the parking brake, lower snowblower to the ground, place transmission in neutral, remove the ignition key, wait for all movement to stop, and then clear the snow from the chute.

A definite pattern of operation is required to thoroughly clean the snow area. These patterns will avoid throwing snow in unwanted places as well as eliminating a second removal of snow

Where it is possible to throw the snow to the left and right (above), as on a long driveway, it is advantageous to start in the middle. Plow from one end to the other, throwing snow to both sides without changing the direction of the discharge guide.

If the snow can only be thrown to one side of the driveway or sidewalk (above), start on the opposite side. At the end of the first pass, rotate the discharge guide 180 degrees for the return pass. At the end of each succeeding pass, rotate the discharge guide 180 degrees to maintain direction of throw in the same area.

MAINTENANCE

Shearbolt Replacement

1. To replace the shearbolt, take off the gearbox shield by removing the two

5/16"NC x 1/2" flange bolts. The hole in the plate helps remove the shearbolt if fragments remain in the hole.

2. Replace the 5/16"NC x 2 1/4" shearbolt a genuine replacement bolt and a 5/16" lockwasher and a 5/16" nut. Replace the gearbox shield with the two 5/16"NC x 1/2" flange bolts.
