REMOVING SNOW

Snow removal conditions vary greatly from light fluffy
snowfaii 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 ali 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 advisabie
to operate the lawn tractor at a siow ground speed
(1 st gear) for safe and efficient snow removal.

» In deep, drifted or banked snow it wiii be necessary to

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

Drive forward into the snow, depress the tractor's
ctutch-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 ailow
the snow thrower to handle the snow without repeated
stopping and starting of forward motion.

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 dear 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 dear even the deepest
of snow piles.
If the snow thrower becomes clogged with snow or

jammed with a foreign object, disengage the snow

thrower immediateiy and shut off the tractor engine.
Undog the snow thrower before resuming operation.

DANGER: Shut off engine and
disengage snow thrower before
unciogging discharge chute. Unciog 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 wheei weights to improve traction.

• Before the first snowfaii, remove ail stones, sticks and
other objects which couid become hidden by the snow.
Permanent obstacles should be marked for visibility.

• Overlap each pass slightly to assure complete snow
removal.

of the rod.

• Replace the trunnion into the hole in the idler arm and

secure it with the hairpin cotter.
Check the operation of the snow thrower, if 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

• 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 wilt not turn, check to see if the shear

bolts have sheared. See figure 65. Two replacement
shear bolts and nylock nuts have been provided with
the snow thrower. For tutu re use order part number
710-0S90A shear bolt and number 47810 nylock nut.

STORAGE RECOMMENDATIONS

Lower the snow thrower to the ground.

Remove the snow thrower from the tractor.
Clean the snow thrower thoroughly. Wash off any salt
deposit which may have dried on the thrower and
housing.
Any bare metal that has become exposed should be
painted or coated with a light oil to prevent rust.
Store in a dry place.

REMOVING THE SPIRAL AUGER HOUSING

Lower the snow thrower to the ground.

Remove the attachment pin. See figure 54 on page

23.
Lock the snow thrower’s fift handle in the down
position to decrease belt tension.

Release the spring tension from the auger belt idler
arm on the bottom of the clutch/idler assembly.

Remove the auger drive belt from the clutch/idler
assembly. See figure 56 on page 23.

Pull the spiral auger housing assembly off of the
tractor.

PARTS TO REMOVE AT END OF SEASON

• Remove the clutch/idler assembly. (The two hanger
brackets and the two shoulder bolts may be left
attached to the tractor frame.)

• Remove the drive belt from the engine pulley.

• If you replaced the engine pulley keeper on a manual
attachment clutch tractor, reinstall the tractor’s original
engine pulley keeper. See figure 33 on page 16 or
figure 39 on page IS.

• if you have a rod operated attachment clutch, remove
the engagement rod from the tractor’s clutch arm. See
figure 29 on page 15.

• if a rear mounted attachment is to be used, remove
the rear weight tray leaving the bolts that you installed
in the sides of the tractor draw bar. Retighfen the
bolts.

• if a front mounted attachment is to be used, remove
the side plates from the tractor. Be sure to assemble
