wear and impact rom contact with ground.
SKID SHOE Controls amount o clearance between
the scraper plate and the ground.
SPIRAL AUGER, R.H. & L.H. Feed snow to the
impeller an at the center o the housing.
BEFORE STARTING
1. Use the end o assembly checklist to veri y that all
instructions have been properly completed.
2. Make sure the skid shoes are adjusted to maintain
adequate ground clearance between the snow
thrower and the type o sur ace to be cleared.
(Re er to the Service and Adjustments section.)
3. Make sure the tractor engine has the correct oil or
winter operation (SAE 5W-30). Re er to tractor
owner's manual.
HOW TO START YOUR SNOW THROWER
1. The tractor should be sitting with the engine
running at ull throttle. Move the attachment clutch
to the engaged position, starting the snow thrower
be ore the tractor's transmission is engaged.
HOW TO STOP YOUR SNOW THROWER
1. To stop the snow thrower, disengage the tractor's
attachment clutch lever or manual clutches or the
clutch switch or electric clutches. Re er to your
tractor owner's manual.
CAUTION: Never direct discharge
towards bystanders or windows. Do not
allow anyone in ront o unit.
CONTROLLING SNOW DISCHARGE
1. To control the direction snow is thrown, the dis-
charge chute has 180 degrees o rotation. Turn the
crank rod clockwise to rotate the chute to the right.
Turn the crank rod counterclockwise to rotate the
chute to the le t.
2. To control the distance snow is thrown, the upper
section o the discharge chute pivots up and down.

RAISING AND LOWERING
3. To raise, push down on the li t handle until the
snow thrower locks in the raised transport position.
4. To lower, push down slightly on the li t handle and
pull the trigger. With the trigger pulled, slowly lower
the snow thrower until it reaches the ground.
CAUTION: Do not operate the snow
thrower without rear wheel weights and
tire chains attached to the tractor to
provide extra traction and stability.
DANGER: Shut o engine and
disengage snow thrower be ore
unclogging discharge chute. Unclog
using a wooden stick, not your hands.
REMOVING SNOW
Snow removal conditions vary greatly rom light lu y
snow all to wet heavy snow. Operating instructions
must be lexible to it the conditions encountered. The
operator must adapt the lawn tractor and snow thrower
to depth o snow, wind direction, temperature and
sur ace conditions.
5. Be ore beginning operation, thoroughly inspect the
area o operation and remove all door mats, sleds,
boards, wires and other oreign objects.
6. The spiral auger speed is directly related to engine
speed. For maximum snow removal and discharge,
maintain high engine r.p.m. ( ull throttle). It is
advisable to operate the lawn tractor at a slow
ground speed (1st gear) or sa e and e icient snow
removal.
7. In deep, dri ted or banked snow it will be necessary
to use ull throttle and a slow ground speed (1st
gear). Drive orward into the snow, depress the
tractor's clutch-brake pedal and allow the spiral
auger to clear the snow. Repeat this method until a
path is cleared. On the second pass, overlap the
irst enough to allow the snow thrower to handle
the snow without repeated stopping and starting o
orward motion.
8. In extremely deep snow, raise the snow thrower
rom the ground to remove the top layer and drive
orward only until the tractors ront tires reach the
uncleared bottom layer o snow. Depress the
tractor's clutch-brake pedal and allow the spiral
auger to clear the snow. Reverse the tractor and
lower the snow thrower to the ground. Drive the
tractor orward until the snow again becomes too
deep. Repeating this process into and out o dri ts
will eventually clear even the deepest o snow
piles.
9. I the snow thrower becomes clogged with snow or
jammed with a oreign object, disengage the snow
thrower immediately and shut o the tractor engine.
Unclog the snow thrower be ore resuming opera-
tion.
OPERATING TIPS
1. Discharge snow down wind whenever possible.
2. To help prevent snow rom sticking to the snow
thrower, allow the snow thrower to reach outdoor
temperature be ore using it. A light coat o wax may
also be applied to the inside sur ace o the snow
thrower housing and discharge chute.
3. Use tire chains to improve traction.
4. Use rear wheel weights to improve traction.
5. Be ore the irst snow all, remove all stones, sticks
and other objects which could become hidden by
the snow. Permanent obstacles should be marked
or visibility.
6. Overlap each pass slightly to assure complete
snow removal.
LUBRICATION
1. Oil all pivot points on the snow thrower.
2. Oil the pivot points o the two idler arms on the
clutch/idler assembly.
3. Apply penetrating oil to the control cables o the
discharge chute.
4. Apply a good grade o spray lubricant to the trigger
assembly and the chute tilt control assembly.
CHECK SCRAPER AND SHOES FOR WEAR
(Refer to figures 33 and 34 on page 19.)
5. The scraper plate and skid shoes on the bottom o
the snow thrower are subject to wear. To prevent
damage to the spiral auger housing, replace plate
and shoes be ore wear is excessive.

each idler pulley. Re er to igure 30 on page 15.
8. Assemble the belt onto the clutch/idler assembly.
Re er to igures 31 and 32 on pages 15 and 16.
SKID SHOE ADJUSTMENT
1. The skid shoes are mounted on each side o the
spiral auger housing. They regulate the distance
the scraper plate is raised above the plowing
sur ace. When removing snow rom a gravel
driveway or and uneven sur ace, it is advisable to
keep the scraper plate as high above the sur ace
as possible to prevent possible damage to the
spiral auger. On blacktop or concrete sur ace, keep
the scraper plate as close to the sur ace as pos-
sible.
2. Raise the snow thrower o the ground and place a
block under each end o the scraper plate. Loosen
the six hex nuts securing the skid shoes to the
housing. Adjust the skid shoes up or down and
retighten the nuts securely. Adjust both skid shoes
to the same height to keep the housing and the
scraper plate level. See igure 33.
LIFT RELEASE CABLE ADJUSTMENT
1. I the li t rod does not lock the snow thrower
securely in the transport position, loosen the upper
hex nut on the li t bracket a ew turns and tighten
the lower hex nut. Re er to igure 24 on page 13.
2. I the li t rod ails to unlock completely to lower the
snow thrower, loosen the lower hex nut on the li t
bracket a ew turns and tighten the upper hex nut.
Re er to igure 24 on page 13.
CLUTCH DISENGAGEMENT ADJUSTMENT
(Only tractors with clutch engagement rods.)
I the spiral auger on the snow thrower does not stop
when the attachment clutch lever on the tractor is
disengaged, then adjustment is necessary. Proceed as
ollows. Re er back to igure 13 on page 9.
1. Place the attachment clutch lever in the disen-
gaged position.
2. Remove the hairpin cotter rom the engagement
rod trunnion and li t the trunnion out o the hole in
the idler arm.

and secure it with the hairpin cotter.
Check the operation o the snow thrower. I the
spiral augers still do not stop, repeat the above
steps until the augers stop when the attachment
clutch lever is placed in the disengaged position.
SPIRAL AUGERS
1. The spiral augers are secured to the auger sha t
with two shear bolts and hex lock nuts. I you hit a
oreign object or i ice jams the augers, the snow
thrower is designed so that the bolts will shear.
2. I the augers will not turn, check to see i the shear
bolts have sheared. See igure 34. Two replace-
ment shear bolts and hex lock nuts have been
provided with the snow thrower. For uture use
