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

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.
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.
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.
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.
3. Disengage the PTO clutch.
IMPORTANT: DO NOT disengage the PTO
clutch with high engine speed (above 1/2"
throttle) since the brake action of the PTO
drive will cause premature wear of the
brake band.
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 all-
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.
terrain 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.
4. Turn the ignition switch OFF
5. Engage the parking brake.
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
Sprocket Alignment
(Figure 15)
ADJUSTMENTS
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).
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.
2
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.
3
1
•
Retighten the knobs.
Skid Shoe Adjustment
(Figure 14)
Figure 15
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.
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.
Loosen skid shoe bolts and adjust according to
instructions below, and securely tighten bolts:
Clearance between cutting edge and
surface:
• Level paved surface :
Adjust to 1/16" to 1/8"
• Uneven or gravel surface: Adjust to 1/2" to 5/8"

OPERATION
SNOW 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.
