The warning system in this manual identifies
potential hazards and has special safety messages that
help you and others avoid personal injury, even death.
DANGER, WARNING and CAUTION are signal
words used to identify the level of hazard. However,
regardless of the hazard, be extremely careful.
DANGER signals an extreme hazard that will cause
serious injury or death if the recommended
precautions are not followed.
WARNING signals a hazard that may cause serious
injury or death if the recommended precautions are
not followed.
CAUTION signals a hazard that may cause minor or
moderate injury if the recommended precautions are
not followed.
Two other words are also used to highlight
information. “Important” calls attention to special
mechanical information and “Note” emphasizes
general information worthy of special attention.
The left and right side of the machine is determined
by sitting on the seat in the normal operator’s
position.

Setting Up the Tractor
Install Rear Wheel Weights and Chains
Install the rear wheel weights and chains. Refer to
Attachment Installation Instructions supplied with the
attachment.
Note: Rear wheel weights may not provide
adequate traction under some
conditions or on inclines. If these
conditions exist, a rear weight box is
recommended.
Install the Rear Attach-A-MaticHitch
Install the rear Attach-A-Matichitch to the tractor;
refer to the Installation Instructions that come with
the Attach-A-Matichitch.
Prepare the Tractor’s Attachment Lift
1. Start the engine.
2. Raise the attachment lift.
3. Set the parking brake and turn the ignition key to
“STOP” to stop the engine. Remove the ignition
key.
4. The two lift arms are attached to the tractor
frame, just ahead of the rear wheels. Secure the
lift arms to the tractor frame with 3/8” x 1”
(25 mm) clevis pins and small hairpin cotters
(Fig. 9).

These pins must be installed when operating with a
blade, snowthrower, or the tiller attachment.
Note: Remove the pins when attaching a
mower.
Installing the Snowthrower on
the Tractor
1. Position the snowthrower frame assembly and its
attachment parts on a level surface with enough
space behind them to accommodate the tractor.
2. Park the tractor behind the snowthrower with the
front wheels lined up to straddle the snowtrower
frame and lift rod (Fig. 10). Lower the
attachment lift and turn the ignition key to
“STOP” to stop the engine. Remove the ignition
key.

3. With the High–Low range selector in neutral
“N,” pull the tractor forward toward the
snowthrower until the end of the snowthrower
frame is just underneath the tractor’s front
Attach-A-Matichitch (Fig. 11).
4. Ensure the latches on the tractor’s front
Attach-A-Maticare open. Then slide the
pulley box completely into the Attach-A-Matic
hitch. Close the latches by rotating them down
(Fig. 11).

Operation
POTENTIAL HAZARD
•When the snowthrower is attached to the
tractor, without additional weight, the
tractor may become unstable.
WHAT CAN HAPPEN
•Loss of traction and stability may cause
loss of tractor control.
HOW TO AVOID THE HAZARD
•NEVER operate the tractor equipped with
the snowthrower, unless rear weights are
installed.
POTENTIAL HAZARD
•Rotating auger can cut off fingers, hands or
other body parts and throw objects.
WHAT CAN HAPPEN
•Contact with rotating auger and thrown
debris can cause severe injury or death.
HOW TO AVOID THE HAZARD
•Stay away from the discharge and auger
openings while operating the snowthrower.
•Keep your hands, feet, and any other part
of your body or clothing away from
concealed, moving or rotating parts.
•Use a stick, not your hand, to remove
obstructions from the discharge chute or
auger housing.
•Before adjusting, cleaning, repairing and
inspecting the snowthrower and before
unclogging the discharge chute, shut off the
engine and wait for all moving parts to
stop. Move the power take off (PTO) to
“OFF” and rotate the ignition key to
“OFF.” Remove the key.
Operating the Power Take Off
(PTO)
The power take–off (PTO) switch engages and
disengages power to the electric clutch.
If the ignition key is in the RUN or LIGHTS position
and the power take off (PTO) is engaged, the PTO
indicator light will be on. When this light is on, it is a
reminder: the implement is being powered and the
starter will not crank while the PTO is engaged.
Always turn off the PTO before getting off the seat.
Engaging the Power Take Off (PTO)
1. Depress the brake pedal to stop the machine.
2. Move the throttle lever to FAST.
IMPORTANT: For best performance, always
use full throttle when the power take off
(PTO) switch is ON.
3. Pull the power take off (PTO) switch to ON (Fig.
33).

Operation
17
Operating the Attachment Lift
Lever
The attachment lift lever (Fig. 34 & 35) is used to
raise and lower various attachments.
Raising Attachments
1. Start the tractor.
2. Pull the attachment lift lever upward until the
latch locks. In this position, the lift will hold the
attachment in the up, or raised position.
POTENTIAL HAZARD
•When the engine is off, attachments in the
raised position can gradually lower.
WHAT CAN HAPPEN
•Someone nearby may be pinned or injured
by the attachment as it lowers.
HOW TO AVOID THE HAZARD
•Always lower the attachment lift each time
you shut off the tractor.
IMPORTANT: The tractor hood must be
closed before the snowthrower is raised.
Lowering Attachments
1. Start the tractor.
2. Push the attachment lift lever downward to
lower the attachment.

Adjusting The Discharge Chute
POTENTIAL HAZARD
•The rotating auger can cut off fingers,
hands or other body parts and throw
objects.
WHAT CAN HAPPEN
•Contact with the rotating auger and thrown
debris can cause sever injury or even death.
HOW TO AVOID THE HAZARD
•Stay away from the discharge and auger
openings while operating the snowthrower.
•Keep your hands, feet, and any other parts
of your body or clothing away from
concealed, moving or rotating parts.
•Use a stick, not you hand, to remove
obstructions from the discharge chute or
auger housing.
•Before adjusting, cleaning, repairing and
inspecting the snowthrower and before
unclogging the discharge chute, shut off the
engine and wait for all moving parts to
stop. Move the power take off (PTO) to
“OFF” and rotate the ignition key to
“OFF.” Remove the key.
The discharge chute can be rotated 180°side to side.
The direction is controlled by turning the crank
handle (Fig. 36).
The chute deflector, on top of the discharge chute, can
be moved up and down to control the height and
distance snow is thrown (Fig. 36).

Tips for Throwing Snow
Remove snow as soon as possible after it falls. This
produces best snow removal results.
Adjust the skids to match the type of surface being
cleaned; refer to Adjusting the Skids, page 24.
The snowthrower is designed to clean snow down to
the contact surface, but there are times when the front
of the snowthrower may tend to ride up. If this
happens, reduce forward speed.
Discharge snow downwind whenever possible, and
overlap each pass to ensure complete snow removal.
If the wheels slip, shift into the High–Low range
lever to Low “L” to reduce forward speed.
Run the snowthrower for a few minutes after clearing
snow so moving parts do not freeze. Engage the
power take off (PTO) to clear any remaining snow
from the inside housing.
Do not overload the snowthrower by clearing snow at
too fast a rate. If the engine slows down, reduce
forward speed.
Always use full throttle (maximum engine speed)
when throwing snow.
