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

Installing
Snowthrower to
Tractor
POTENTIAL
• When 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 AV
• NEVER operate tractor, equipped with
snowthrower, unless 100lb rear wheel
weights are installed.
1. Install lift tube to housing with 5/8” flat washer
and hairpin cotter (Fig. 6).

Operation
Tips
Remove snow as soon as possible after it falls. This
produces best snow removal results.
Adjust skids to match the type of surface being
cleaned; refer to Adjusting Skids.
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 wheels slip, shift into a lower gear to reduce
forward speed.
Run snowthrower for a few minutes after clearing
snow so moving parts do not freeze. Engage power
take off (PTO) to clear any remaining snow from
inside housing.
for Throwing
Snow
Do not overload snowthrower by clearing snow at too
fast a rate. If engine slows down, reduce forward
speed.
Always use full throttle (maximum engine speed)
when throwing snow.
In wet or slushy conditions, clogging of the discharge
chute will be reduced by maintaining maximum
engine speed and by not overloading the engine.
In some snow and cold weather conditions, some
controls and moving parts may freeze. Therefore,
when any control becomes hard to operate, stop the
machine and wait for all moving parts to stop; then
check all parts for freeze up. DO NOT USE
EXCESSIVE FORCE AND TRY TO OPERATE
THE CONTROLS WHEN FROZEN. Free all
controls and moving parts before operating.

POTENTIAL HAZARD
• If you leave the key in the ignition switch, someone could start the engine.
WHAT CAN HAPPEN
• Accidental starting of the engine could seriously injure you or other bystanders.
HOW TO AV
• Remove the key from the ignition switch and pull the wire off the spark plug before
you do any maintenance. Also push the wire aside so it does not accidentally contact

Greasing
and Lubrication
Service Interval/Specification
Grease and oil the machine after every 25 operating
hours or once a year, whichever occurs first.
Grease Type: General-purpose grease.
Oil Type: SAE 10W or 10W30.
How to Grease
1. Disengage the power take off (PTO), set the
parking brake, and turn the ignition key to
“OFF” to stop the engine. Remove the key.
2. Clean the grease fittings with a rag. Make sure to
scrape any paint off the front of the fitting(s).
3. Connect a grease gun to the fitting. Pump grease
into the fittings.
Oil Drive Chain
1. Disengage the power take off (PTO), set the
parking brake, and turn the ignition key to
“OFF” to stop the engine. Remove the key.
2. Coat the entire chain with oil and allow to
penetrate each roller (Fig. 25).
3. Place a few drops of oil on discharge chute
rotator shaft and discharge chute mounting
(Fig. 25).
4. Wipe off excess oil.
4. Wipe up any excess grease.
Where to Add Grease
1. Lubricate the drive shaft bearings (Fig. 24).

Maintenance
Adjusting
Skids
The distance between the scraper blade and the
ground is controlled by skids on each side of the
housing. The height can be adjusted so the scraper
blade will not catch on uneven surfaces
1. Disengage the power take off (PTO), set the
parking brake, and turn the ignition key to
“OFF” to stop the engine. Remove the key.
2. Move snowthrower to a level surface.
3. Loosen nuts securing skids to the housing until
the skids slide up and down easily (Fig. 26).
4. Raise or lower skids equally on both sides, to
obtain level scraping action, and tighten nuts
(Fig. 26).
Note: On smooth, paved surfaces, scraper
blade can be close to the surface On
uneven, gravel or crushed rock
surfaces, adjust skids to raise scraper,
to prevent catching or picking up
rocks.
Reversing
Scraper Blade
The scraper blade contacts the ground preventing
damage to the snowthrower housing. Periodically
inspect the scraper blade for wear. When scraper
becomes worn, before working surface contacts the
housing, reverse the scraper blade.
1. Disengage the power take off (PTO), set the
parking brake, and turn the ignition key to
“OFF” to stop the engine. Remove the key.
