pecially when operating in reverse.
PREPARATION
1.
8.
Thoroughly inspect the area where the equipment
is to be used and remove all door mats, sleds,
boards, wires and other foreign objects.
Disengage all clutches and shift into neutral before
starting engine or motor.
Do not operate equipment without wearing ade-
quate winter outer garments. Wear footwear which
will improve footing on slippery surfaces.
Handle fuel with care, it is highly flamamble.
(A) Use approved fuel container.
(B) Never add fuel to a running engine or hot en-
gine.
{C) Fill fuel tank outdours with extreme care.
Never fill fuel tank indoors.
(D) Replace gasoline cap securely and wipe up
spilled fuel.
(E) Open doors if engine is run in the garage-
exhaust fumes are dangerous.
Adjust collector housing height to clear gravel or
crushed rock surface.
Never attempt to make any adjustments while en-
gine or motor is running (except where specifically
recommended by manufacturer}.
Never operate the snow thrower without good vis-
ibility or light.
Let engine and machine adjust to outdoor tempera-
tures before starting to clear snow.
OPERATION

If the unit should start to vibrate abnormally, stop
the engine (motor) and check immediately for the
cause. Vibration is generally a warning of trouble.
Stop engine (motor) whenever you leave the oper-
ating position, before unclogging the collector/
impeller housing or discharge guide, and making
any repairs, adjustments, or inspections.
Take all possible precaution when leaving the ve-
hicle unattended, disengage the power take-off,
lower the attachment, shift into neutral, set the
parking brake, stop the engine, remove the key.
When cleaning, repairing, or inspecting make cer-
tain collector/impeller, and all moving parts have
stopped. Disconnect spark plug wire and keep
wire away from plug to prevent accidental start-
ing. Disconnect cord on electric motors.
Do not run engine indoors, exhaust fumes are
dangerous.
Do not clear snow across the face of siopes. Ex-
ercise extreme caution when changing direction
on slopes. Do not attempt to clear steep slopes.
Never operate snow thrower without guards,
plates, or other safety protective devices in place.
Never operate snow thrower near glassenclosure,
automobiles, window wells, drop-offs, etc., with:
out proper adjustment of snow discharge angle.
Keep children and pets away.
Do not overload machine capacity by attempting
to clear snow at too fast a rate.
Never operate machine at high transport speeds
on slippery surfaces. Use care when backing.
Never direct discharge at bystanders or allow any-
one in front of unit.
Disengage power to collector/impeller
transporting or not in use.
Only use attachments and accessories approved by
manufacturer of snow thrower (such as wheel
weights, counter weights, cabs, etc.).
when
MAINTENANCE AND STORAGE
1.
Check shear bolts, engine mounting bolts, etc. at
frequent intervals for proper tightness to be sure
equipment is in safe working condition.
Never store machine with fuel in the fuel tank in-
side a building where open flame or spark is pres-
ent. Allow engine to cool before storing in any
enclosure.
Always refer to owner's guide instructions for im
portant details if snow thrower is to be stored fo,
an extended period.
Run machine a few minutes after throwing snow
to prevent freeze up of collector/impeller.

CONTROLS
The thrower controls are conveniently located at the
operators position on the tractor.
LIFT CONTROL LEVER
The lift control lever which is used to raise and lower
the snow thrower is located on the right hand side
of tractor. To raise the snow thrower, depress the but-
ton on the lift control lever, pull back on the lever
and release the button. To lower snow thrower,
depress the button on the lever, push the lift control
lever forward slowly until snow thrower reaches
ground level and release the button.
ma) NOTE
The snow thrower can be lifted off the
ground approximately 4 inches. Do
not attempt to force the lift lever to
raise the snow thrower further.
DISCHARGE CHUTE CONTROL CRANK
The discharge chute control crank is located on the
left hand side of the snow thrower. The chute crank
controls the direction in which snow is thrown. The
discharge radius is 180 © degrees. Turn crank to the
right to direct snow to the right hand side. Turn to
the left to direct snow to left hand side.
P.T.O. CONTROL
Electric PT.O. Models: The PT.O. switch is located on
the left side of the instrument panel.
Manual PT.O. Models: The PT.O. lever is located on
the left side of the pedestal.
The spirals are engaged by placing the P.T.O. control
in the ON or ENGAGED position. Refer to the lawn
tractor owners manual for proper activation instruc-
tions. Place the PT.O. control in the OFF or
DISENGAGED position to stop the snow throwing
action.
10
OPERATION
The snow thrower is capable of handling heavy snow
conditions. If given the opportunity to function within
reasonable requirements, it should give many years
of service. Become fully familiar with all aspects of
both the tractor and snow thrower prior to its usage.
Do Not remove any guards or covers while operating
tractor and thrower.
BEFORE PLACING SNOW THROWER INTO
OPERATION
1. Check all nuts and bolts for correct tightness.
Be sure that all parts are properly assembled.
2. Test all controls for smooth operation.
A. Discharge chute control crank
B. Lift control lever
ma) NOTE
Start engine and engage PTO switch.
If spirals run in reverse, belt is
assembled incorrectly. Refer to step
number 18 through 20 of assembly
instructions.
3. Check the tractor and thrower to make certain
both are in good operating condition.
4. Fill gas tank out-of-doors. Avoid spilling gasoline
over engine. Do not fill tank while engine is run-
ning. Wipe up any spilled gas.
OPERATING SPEED
Start tractor engine and run at full throttle. The spiral
speed is directly related to engine speed. For max-
imum snow removal and discharge, maintain high
engine R.PM. (full throttle}. The tractor's forward
speed is controlled by selecting one of the forward
speeds. It is advisable to operate the tractor at a slow
ground speed (1st gear) for safe and efficient snow
removal. Slowly engage (push forward) the lift
handle.
SNOW CONDITIONS
Snow removal conditions vary greatly from light
fluffy snowfall to wet heavy snow. Therefore,
operating instructions must be flexible to fit
onditions encountered. The operator must adapt the
Jractor snow thrower to depth of snow, wind direc-
tion, temperature and surface conditions.
DEEP OR DRIFTED SNOW
In deep, drifted or banked snow, it will be necessary
to use full throttle and first speed. Drive the spiral
into the snow, disengage tractor drive clutch and
allow spiral to clear the snow. Repeat this method
untit a path is cleared. On the second pass, overlap
the first enough to aliow the spiral to handle the snow
without repeated clutching and declutching of the
tractor.
In extremely deep snow, raise thrower from the
ground and drive tractor ahead in the deep snow to
remove top layers first. Do not drive tractor into 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 ground. Drive tractor ahead and repeat process
to remove balance of snow. Working with repeated
passes into and out of drifts will eventually move
even the deepest of snow piles.
A
If snow thrower becomes plugged
with snow or jammed due to hitting
a foreign object, disengage snow
thrower immediately and stop tractor
engine. Clear snow from chute if
plugged before resuming operation.
mm) NOTE
If spiral is jammed or bent from hit-
ting a foreign object, stop tractor
engine. Remove spark plug wire from
spark plug and then remove foreign
object from spiral. If spiral damage is
noted, repair prior to continuing
operation. Then replace spark plug
wire and resume operation.
OPERATING TIPS
1. Whenever possible, discharge snow down wind.
2. Do not Attempt to remove ice or hard packed
frozen snow.
3. Always overlap each pass slightly to assure
complete snow removal.
A. А frozen or stuck spiral or chute must be broken
loose or thawed with care. When attempting to
loosen frozen or jammed spiral, shut off tractor
engine and remove spark plug wire. Never
attempt to clear snow thrower at any time with
tractor engine running.
11
mm) NOTE
When snow thrower and tractor are
not in use, lower snow thrower to the
ground to prevent excess weight on
front tires.
USE OF TIRE CHAINS
Tire chains should always be used when extra trac-
tion is needed. Théy add maneuvertability in handl-
ing snow removal jobs.
ADJUSTMENTS
À mn
When making any adjustments, turn
tractor engine off.
SKID SHOE ADJUSTMENT
The skid shoes are mounted on each side of spiral
housing. These regulate the distance the shave plate
is raised above the plowing surface. When remov-
ing snow from a gravel driveway or an uneven sur-
face, it 1s advisable to keep shave plate as high above
the surface as possible to prevent possible damage
to spiral.
On blacktop or concrete surface, keep shave plate
as close to the surface as possible. Skid shoes can
be adjusted so that shave plate will rest directly on
the surface. Turning skid shoes around or inverting
them will allow even wear on skid shoes.
Raise snow thrower off the ground and place a block
at each end of shave plate. Loosen 4 hex nuts secur-
ing skid shoes to spiral housing (2 nuts on each side).
Move skid shoes up or down to desired position and
tighten nuts securely. Adjust both skid shoes to the
same height to keep spiral level. See figure 21,
FIGURE 21
CHUTE DEFLECTOR ADJUSTMENT
The upper chute deflector mounting on the top of
the chute determines the distance snow is thrown.
Moving top of deflector down decreases distance of
throw and raising deflector increases distance of
throw. Operator must get off tractor to make this ad-
justment. Disengage spirals and turn engine off
before making this adjustment.
To adjust, loosen hand knob on the side of chute
deflector and pivot to desired position. Retighten
hand knob. See figure 22.
\ ,[
Chute Deflector
: Hand Knob
FIGURE 22
SPIRAL DRIVE CHAIN ADJUSTMENT
Excessive slack in spiral drive chain due to normal
chain stretch can be removed by adjusting spiral
housing nuts.
To adjust spiral chain:
1. Disengage snow thrower and loosen the
adjusting nut 2 or 3 complete turns. See figure
23.
2. Move adjusting nut down as needed.
mm) NOTE
Do not overtighten chain. A correctly
adjusted chain will have a slight
amount of slack. An overtightened
chain will result in early failure of
chain.
3. Tighten adjusting nut to secure chain adjust-
ment. Check chain clearance. It must clear chain
guard assembly. Test chain and repeat adjust-
ment if necessary until all excess slack is
removed.
FIGURE 23
LUBRICATION
1. Spiral drive chain: Lubricate chain every 40
hours with No. 30 oil. It is important that oil
reaches inside each roller, Wipe off excess c
from chain. See figure 24.

FIGURE 24
2. Pivot and friction points: To maintain smooth
and free operation, apply a few drops of No. 30
oil as required to all pivot and friction points.
The spiral and idler pulley bearings are self-
lubricating. However, periodic lubrication with No. 30
oil will lengthen service life.
MAINTENANCE
SHAVE PLATE AND SKID SHOES
The shave plate and skid shoes on the bottom of the
snow thrower are subject to wear. They should be
checked periodically and replaced when necessary.
Skid shoes and shave plate are reversible for longer
life. The skid shoes may also be inverted to extend
their life even further.
Replace shave plate and skid shoes before wear is
excessive, Failure to do so will result in damage to
the spiral housing.
OFF-SEASON STORAGE
At the end of the snow season, the following steps
are recommended:
1. Remove snow thrower assembly from tractor.
2. Wash off any salt deposit which may have dried
on the thrower and housing. Paint or cover ex-
posed metal with a light coat of oll.
3. Follow lubrication recommendations. Thrower
drive chain must be oiled thoroughly to prevei
rust from forming. The preferred method is tu
remove the chain and soak in oil for several
hours before reinstalling.
4. Store thrower in a dry place.
