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

Rotatio n 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.

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 SLOW LY engage

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

OPERATION
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

from rolling freely with the engine stopped.
However, if the machine is parked on a
slope, it is necessary to ENGAGE the

creeping. This is due to a small amount of
slippage in the hydrostatic transmission,
especially when the transmission fluid is
warm.

Recommendatio n For Snow blowing
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. W hen 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. W hen snowblowing, operate the engine at
or near FULL THROTTLE for the best
snowblowing action. The engine is
designed to operate at full speed.
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 th e parking brake.
WARNING: Remove the key from the
ignition switch when leaving the machine
unattended. This will prevent children and
inexperienced operators from starting the
engine.
OM 0352SB-A 17
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.

drive shaft disengaged, and all movement
has stopped before making any
adjustments.
Deflector Adj ustment
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 :
• Uneven or gravel surface: Adjust to 1/2" to 5/8"

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 fu ll engine RPM power when removing wet, sticky snow. Low engine RPM power
will tend to clog the chute.
WARNING
To avoid serious personal injury:
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
Do not use hands or feet to unclog chute. Do not attempt
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.
OM 0352SB-A
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.
