ADJUSTMENTS & REMOVAL
Skid shoe adjustment:
LEVEL PAVED SURFACE: Adjust skid shoes to
allow 3/16" to 1/4" clearance between cutting edge
and surface.
UNEVEN OR GRAVEL SURFACE: Adjust skid shoes
to allow 1/2" to 3/4" clearance between cutting edge
and surface.
STEP 3
ADJUSTMENTS
Drive pulley adjustment:
NOTE: Place the tractor horizontally on a flat surface.
1.The tractor pulley (item 60) and the snowblower
pulley (item 61) must be well aligned (distance B
must be close to 0’’ as possible) Make sure there is
no contact between the two belts when the
snowblower is in the highest position.
2.For tractor without electric clutch : do the same
tests as in snowblower installation section,
paragraph 9. If the snowblower starts and proper
tension is used, the pulleys are misaligned too
much.
If at the highest position the two belts come into
contact with each other, there is not enough space
between the pulleys.
3.On 440 tractors, to prevent snowblower from
contacting front of tractor during full lifts, position
the lift cylinder and pin into the bottom/rear hole on
the lift arm as shown on picture:
NOTE: Failure to position the lift cylinder as shown
can result in damage to the tractor and or the
snowblower.
When you have confirmed the alignment, put thread
locking on set screw and torque at 183 lbs-in.
STEP 4
SNOWBLOWER REMOVAL INSTRUCTIONS:
1.Lower parking stand.
2.Lower the snowblower and stop engine
3.Disconnect the two hydraulic hoses and install dust covers.
4.Remove the drive belt and release the quick hitch. Start the engine and back out carefully.
5.Remove the weights from the weight bar for the 4 wheel drive unit.
TO PREVENT INJURIES: STOP THE MOTOR. APPLY PARKING BRAKE. REMOVE THE IGNITION KEY.
DISCONNECT THE WIRE FROM THE SPARK PLUG(S) AND KEEP AWAY FROM SPARK PLUG(S) TO
PREVENT ACCIDENTAL STARTING.

11
OPERATION
STEP 5
OPERATIONING INSTRUCTIONS:
1. Make sure the snowblower is clear of snow before engaging the snowblower.
2. Make sure that the auger and impeller operate freely.
3. Start the tractor engine
IMPORTANT: USE FULL ENGINE R.P.M. WHEN REMOVING WET OR STICKY SNOW. LOW R.P.M.
WILL TEND TO PLUG THE CHUTE.
4. Engage P.T.O. slowly and maintain engine speed at 3/4 to full throttle.
5. Low range works best for most conditions. Adjust speeds to match snow conditions. The snowblower
works best with plenty of snow being fed into the blades. In light snow (4’’ to 6’’ or 10 to 15 cm) increase
travel speed.
6. Float position may be used, but carrying some of the weight with the power unit gives better traction. May
require frequent lifting and lowering on 4-wheel drive units. If drive belts slips, adjust drive belt tension
according to power unit manual. Never put down force on the snowblower.
7. Rotate chute using the auxiliary hydraulic control lever. Try to blow snow with the wind on windy days.
8. Set the angle of the deflector according to the distance the snow must be thrown and to prevent property
damage. To change the deflector angle, loosen the two deflector knobs & adjust the deflector to the
appropriate angle and retighten the two knobs securely. If equipped with an Electric Deflector Kit, use the
toggle switch for up or down deflector movement.
9. When removing snow, do not use the snowblower as a dozer blade to push snow. Allow snowblower to
ingest snow at its own speed. If the speed of your tractor is too fast, the snowblower may become
overloaded and plug. For best results, raise the snowblower and remove a top layer of snow. A second
pass with the snowblower will remove the remaining snow.
ASSURE CLEAR DISTANCE IN THE DIRECTION OF THROWING SNOW. OBJECTS CAN BE
PROPELLED FROM BLOWER CAUSING POSSIBLE DAMAGE TO PROPERTY OR INJURY TO
BYSTANDERS.
CLEARING A CLOGGED DISCHARGE CHUTE:
Hand contact with the rotating impeller inside the discharge chute is the most common cause of injury
associated with snowblowers. Never use your hand to clean out the discharge chute.
To clear the chute:
1. Lower snowblower to the ground and set parking brake.
2. SHUT THE ENGINE OFF & REMOVE KEY!
3. Wait 10 seconds to be sure that all moving parts such as the impeller blades have stopped moving.
4. Disconnect wire from the spark plug(s) and keep wire away to prevent accidental starting.
5. Always use a clean-out tool (chute shovel) supplied with this snowblower, NEVER YOUR HANDS.
BE ALERT! WATCH FOR BURIED OBJECTS IN THE SNOW WHICH COULD BE THROWN OR CAUSE
DAMAGE TO MACHINE.
NEVER TRAVEL AT SPEEDS THAT WOULD CAUSE DAMAGE TO THE MACHINE OR INJURY TO THE
OPERATOR IF THE MACHINE WERE TO BE STOPPED SUDDENLY BY AN IMMOVABLE OBJECT.
READ THE TRACTOR OWNER’S MANUAL CAREFULLY. BE THOROUGHLY FAMILIAR WITH THE
CONTROLS & PROPER USE OF THE ATTACHMENT. KNOW HOW TO STOP THE ATTACHMENT &
DISENGAGE THE CONTROLS QUICKLY.
