RAISING AND LOWERING

3.  To raise, push down on the lift handle until the snow 

thrower locks in the raised transport position.

4.  To lower, push down slightly on the lift 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 off engine and 

disengage snow thrower before 
unclogging discharge chute. Unclog using 
a wooden stick, not your hands.

REMOVING SNOW 

Snow removal conditions vary greatly from light fl uffy snowfall 
to wet heavy snow. Operating instructions must be fl exible 
to fi t the conditions encountered. The operator must adapt 
the lawn tractor and snow thrower to depth of snow, wind 
direction, temperature and surface conditions.
5.  Before beginning operation, thoroughly inspect the area 

of operation and remove all door mats, sleds, boards, 
wires and other foreign objects.

6.  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 effi cient snow removal.

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

use full throttle and a slow ground speed (1st 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 fi rst enough to allow the snow thrower to 
handle the snow without repeated stopping and starting 
of forward motion.

8.  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 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 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.

9.  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.

OPERATING TIPS

1.  Discharge snow down wind whenever possible.
2.  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.

3.  Use tire chains to improve traction.
4.  Use rear wheel weights to improve traction.
5.  Before the fi rst snowfall, remove all stones, sticks and 

other objects which could become hidden by the snow. 
Permanent obstacles should be marked for 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 of the two idler arms on the clutch/idler 

assembly.

3.  Apply penetrating oil to the control cables of the discharge 

chute.

4.  Apply  a  good  grade  of  spray  lubricant  to  the  trigger 

assembly and the chute tilt control assembly.

CHECK SCRAPER AND SHOES FOR WEAR

(Refer to fi gures 34 and 35 on page 19.)

5.  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.
