Move the tractor outside into the air.
No person should be allowed near the working area when the snow thrower is beingoperated.
Check overhead clearance carefully before
driving under low hanging tree branches, or
other situations where the operator may be
struck or pulled from the tractor.
AFTER OPERATING
Disengage power to rotor/collector when
transporting or not in use.
Lower equipment to ground before leaving
tractor to avoid the possibility of the equip-
ment dropping and causing injury.
Watch
3
No one should operate the machine while
intoxicated or while taking medication that
impairs the senses or reactions.
To reduce the possibility of unattended move-
ment of the tractor or its use by unauthorized
operators which could result in an accident
and injury, always turn off the power take-off,
shift transmission into neutral, set the parking
brake, stop the engine, and remove ignition
key when leaving the machine unattended.
GENERAL
The snow thrower controls are conveniently
located at the operator's position. By engaging the P.T.G. clutch, snow is thrown through
the discharge chute by the motion of the
rotor/collector. Turning the discharge chute
control rod directs snow discharge and the
angle of the deflector cap controls the dis-tance
snow is thrown.
To become familiar with the snow thrower
controls, operate the tractor and snow
thrower in a clear area before attempting to
remove snow.
Snow Conditions
Snow removal conditions vary so greatly from
the first light fluffy snowfall to wet heavy snow
that operating instructions must be flexible to
fit the snow removal encountered. The operator must adapt the tractor and snow thrower
to depth of snow, wind direction, temperature
and surface conditions.
Operating Speed
The rotor/collector speed is directly related
to engine speed. For maximum snow removal
and discharge maintain high engine A.P.M.
(full throttle). Operate the tractor at a slow
ground speed for safe and efficient snow
removal (Usually 1st gear at full throttle).
Deeper Drifted Snow
In deep, drifted or banked snow, it will be necessary to drive the rotor/collector into thesnow,
disengage tractor clutch and allow to
clear the snow.
Repeat this method until a path is cleared. On
the second pass overlap the first enough to
allow the rotor/collector to handle the snow
without repeated clutching and declutching of
the tractor.
In extremely deep snow, raise thrower from
ground and drive ahead into snow to remove
top layers first, keeping tractor out of snow
bank where snow has not been removed to
ground level.
Disengage tractor clutch and allow thrower to
clear the snow. Reverse tractor and lower
thrower to the ground. Drive tractor ahead
and repeat process to remove balance ofsnow.
Working with repeated passes into and out of
drifts will move even the deepest of snowpiles.
Operating Tips
Whenever possible discharge snow downwind.
Do not attempt to remove ice or hard packed
frozen snow.
Always overlap each pass slightly to assure
complete snow removal.
Never attempt to clear snow thrower at any
time with tractor engine running.
Methods of Operating
A definite pattern of operating is required to
thoroughly clean the snow area. This pattern
will avoid a second removal of snow and avoid
throwing snow in unwanted places.
Where it is possible to throw snow to right and
left, as on a long driveway, it is advantageous
to start in the middle. Work from one end to
the opposite end throwing snow to either side
without changing the direction of discharge
chute.
If snow can only be thrown to one side of the
driveway or sidewalk, start on the oppositeside.
At the end of each succeeding pass,
rotate the chute 1800 to continue to throw
snow into the same area.
Tire ChainsThe
use of tire chains is recommended for
extra traction.

RUNNERS
ADJUSTING AND OPERATING
1 -Rotor/collector housing
2 -Flange
3 -Direction of movement to raise housing
The snow thrower is shipped with its runners
mounted with the flanges to the inside at the
right and left sides of the rotor/collector
housing.
The runners may be removed and reinstalled
with the runner flanges towards the outside to
allow the rotor/collector to operate closer to
the ground surface, if necessary.
The runners maintain the desired distance
above the ground for the rotor/collector hous-
ing when the snow thrower is being operated.
When removing snow from an uneven surface
or a gravel path or driveway, the runners
should be adjusted to hold the rotor/collector
housing high above the ground surface.
This will prevent possible damage to the
rotor/collector and keep stones or other
material from being thrown with the snow,
which could result in damage to property or
personal injury. Such adjustment will also
reduce excessive wear on the snow thrower
parts.
4 -Runner
5 -Direction of movement to lower housing
6 -Wooden block
On a smooth and even surface, such as concrete or blacktop, the runners may be
adjusted to allow the rotor/collector to work
close to the ground.
To adjust the runners, raise the snow thrower
and place a wooden block or other sturdy
object under each side of the rotor/collector
housing.
Loosen the nuts securing the runners to the
rotor/collector housing and move the runners
to the position required for adequate ground
clearance and retighten the nuts.
Both runners should be adjusted to the same
height to keep the rotor/collector housing
level.
Runners are subject to wear due to constant
use and are designed for easy replacement.
Replace before wear is excessive to prevent
possible damage to the rotor/collector hous-
ing.

by turning the discharge chute control rod.
A slight resistance should be noticed. If no
resistance is felt, it may be necessary to
tighten the eyebolt lock nut an additional 1/8
turn.
Tighten the eyebolt lock nut only until the discharge chute holds its position. Do not over-
tighten.
The position of the deflector cap on top of the
discharge chute determines the distance that
snow can be thrown.
To increase the distance that snow is thrown,
move the deflector cap upward. To decrease
the distance, move the deflector cap downward.

ADJUSTING AND OPERATING
If the up stop brackets are tight against the
underside of the front axle, or the space between the top of the stops and the underside of
the front axle is greater than recommended,
when the snow thrower is raised to the
transport position, a lift height adjustment
should be made.
To adjust the snow thrower transport liftheight,
raise the snow thrower to a position
that will provide the correct clearance be-
tween the top of the up stop brackets and the
underside of the front axle and place blocks
under each side of the snow thrower housing
to support it at this height.
1 -Front axle
2 -Lower mounting frame
3 -Up stop bracket (one each
side of mounting frame)
For maximum ground clearance when the lift
lever is operated to raise the snow thrower to
the transport position, the space between the
top of the up stop brackets (located on the
right and left side of the lower mounting
frame) and the underside of the front axle
must measure 118 to 1/4-inch. (See Illustra-tion).
Move the snow thrower lift lever forward to
the full "lowered" position. Loosen the front
and rear lock nuts on the adjusting bolt in the
lift extension assembly at the left side of the
snow thrower mounting frame.
Move the lift lever rearward to the full
"raised" position. Slide the adjusting bolt forward to place the bolt head against the lower
mounting frame stop.
Holding the adjusting bolt from turning,tighten
the front lock nut to hold the bolt head
firmly against the frame stop. Holding the

LUBRICATION
The snow thrower is designed to require a
minimum amount of lubrication; however, the
points that are to be lubricated should be serviced regularly at the intervals listed.
Keep the lubricating gun nozzle clean and
wipe dirt from grease fittings before lubricat-ing.
To maintain smooth and free operation, apply a few
drops of oil as required to all pivot points before
operation.

Care should be taken to keep lubricant from
coming in contact with V-belts or pulleys.
The symbols shown around the reference
numbers in illustrations indicate the intervals
of lubrication. Paragraph numbers corres-
pond to reference numbers in the illustra-
tions.

cient grease to flush out the old grease and dirt.
31
At the end of the snow season, the following
steps should be taken before storing the
snow thrower.
Remove the snow thrower from the tractor.
Wash off any salt deposit or other foreign
matter which may have gathered and dried on
the snow thrower housing.
"Touch up" all rusted or chipped painted sur-faces,
by sanding and cleaning up the
affected areas before painting.
Check for any damaged or bent parts. Make
sure all idler pulleys and associated parts
turn and move freely.
Should any service parts need replacement,
they should be ordered early prior to storing
the snow thrower.
This will give your International Harvester
dealer enough time to provide the needed
parts for installation before the next snowseason.
Lubricate the snow thrower as outlined in the
"LUBRICATION" instructions.
Store the snow thrower in a dry and protected
area when not in use. Leaving it outdoors
exposed to the weather elements will result in
materially shortening its life.
BEFORE STARTING THE SNOW THROWER
AFTER STORAGE
Make sure all bolts, nuts and fasteners are
properly tightened.
Make sure all idler pulleys and associated
parts turn freely.
This can save wasted time and needless
expense.
