A

REMOVING SNOW

Snow removal conditions vary greatly from light fluffy
snowfall to wet heavy snow. Operating instructions must
be flexible to fit the conditions encountered. The operator

must adapt the lawn tractor and snow thrower to depth of

snow, wind direction, temperature and surface conditions.

• Before beginning operation, thoroughly inspect the
area of operation and remove all door mats, sleds,
boards, wires and other foreign objects.

• The spiral auger speed is directly related to engine
speed. For maximum snow removal and discharge,

maintain high engine r.p.m. (full throttle). It is advisable

to operate the lawn tractor at a slow ground speed

(1st gear) for safe and efficient snow removal.

• In deep, drifted or banked snow it will be necessary to

use full throttle and a slow ground speed (1 st gear).

Drive forward 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 first enough to allow
the snow thrower to handle the snow without repeated

stability.

In extremely deep snow, raise the snow thrower from
the ground to remove the top layer and drive forward
only until the tractors front tires reach the uncleared
bottom layer of snow. Depress the tractor's clutch­brake pedal and allow the spiral auger to clear the
snow. Reverse the tractor and lower the snow thrower
to the ground. Drive the tractor forward until the snow
again becomes too deep. Repeating this process into
and out of drifts will eventually clear even the deepest
of snow piles.

If the snow thrower becomes clogged with snow or
jammed with a foreign object, disengage the snow
thrower immediately and shut off the tractor engine.
Unclog the snow thrower before resuming operation.

DANGER: Shut off engine and
disengage snow thrower before
unclogging discharge chute. Unclog using

A

a wooden stick, not your hands.

OPERATING TIPS

• Discharge snow down wind whenever possible.

• To help prevent snow from sticking to the snow thrower,
allow the snow thrower to reach outdoor temperature
before using it. A light coat of wax may also be applied
to the inside surface of the snow thrower housing and
discharge chute.

• Use tire chains to improve traction.

• Use rear wheel weights to improve traction.

• Before the first snowfall, remove all stones, sticks and
other objects which could become hidden by the snow.

Permanent obstacles should be marked for visibility.

• Overlap each pass slightly to assure complete snow
removal.

MAINTENANCE

CUSTOMER RESPONSIBILITIES

• Read and follow the maintenance schedule and the maintenance procedures listed in this section.
MAINTENANCE SCHEDULE

Fill in dates as you
complete regular service. Service Dates

Check for loose fasteners
Check scraper and shoes for wear X X
Cleaning X
Lubrication Section X

LUBRICATION

• Oil all pivot points on the snow thrower.

• Oil the pivot points of the two idler arms on the clutch/

idler assembly.

• Apply penetrating oil to the control cables of the

discharge chute.

• Apply a good grade of spray lubricant to the trigger

assembly and the chute tilt control assembly.

X

CHECK SCRAPER AND SHOES FOR WEAR
(Refer to figures 27 and 28 on page 18.)

• The scraper plate and skid shoes on the bottom of the
snow thrower are subject to wear. To prevent damage
to the spiral auger housing, replace plate and shoes
before wear is excessive.

SERVICE AND ADJUSTMENT

]

CAUTION: Before servicing or adjusting
the snow thrower, shut off the engine, remove
the spark piug wire(s), set the parking brake

A

and remove the key from the tractor ignition.

REPLACING AUGER BELT

• Disengage the tractor's attachment dutch.

• Lower the snow thrower to the ground.

• Remove the attachment pin.

• Lock the snow thrower's iift handie in the down
position to decrease beit tension.

• Reiease the spring tension from the auger beit idier
arm on the bottom of the ciutch/idier assembly.

• Remove the auger drive belt from the ciutch/idier
assembly and from the spiral auger housing.

• Install new belt over top of large auger drive pulley
and under the two side idler pulleys. Twist the belt 1/4
turn to seat the "V" of the belt in the groove of each

idler pulley. Refer to figure 23 on page 14.

• Assemble the belt onto the ciutch/idier assembly.

SKID SHOE ADJUSTMENT

• The skid shoes are mounted on each side of the spiral
auger housing. They regulate the distance the scraper
plate is raised above the plowing surface. When

removing snow from a gravel driveway or and uneven

surface, it is advisable to keep the scraper plate as

high above the surface as possible to prevent possible
damage to the spiral auger. On blacktop or concrete
surface, keep the scraper plate as close to the surface
as possible.

• Raise the snow thrower off the ground and place a
block under each end of 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 figure 27.

LIFT RELEASE CABLE ADJUSTMENT

• If the lift rod does not lock the snow thrower securely
in the transport position, loosen the upper hex nut on
the lift bracket a few turns and tighten the lower hex
nut. Refer to figure 16 on page 12.

• If the lift rod fails to unlock completely to lower the
snow thrower, loosen the lower hex nut on the lift
bracket a few turns and tighten the upper hex nut.

Refer to figure 16 on page 12.

SPIRAL AUGERS

• The spiral augers are secured to the auger shaft with
two shear bolts and nylock nuts. If you hit a foreign
object or if ice jams the augers, the snow thrower is
designed so that the bolts will shear.

• If the augers will not turn, check to see if the shear
bolts have sheared. See figure 28. Two replacement
shear bolts and nylock nuts have been provided with
the snow thrower. For future use order part number
710-0890A shear bolt and number 47810 nylock nut.

18

STORAGE RECOMMENDATIONS
