REPLACING
AUGER
BELT
•
Raise the snow thrower to the transport position.
•
Release the spring tension on the drive belt idler.
•
Release the spring tension on the auger belt idler.
•
Remove the auger belt from the clutch/idler assem-
bly and from the spiral auger housing.
•
Install new belt over top of large auger drive pulley
and underneath
the two side idler pulleys. Twist the
belt 1/4 tur.n to seat the "V" of the belt in the grooye
of each idler pulley.
•
Assemble the belt onto the clutch/idler
assembly as
instructed for figure 18 on page 11.
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. See figure 10 on page 8.
•
If the lift rod fails to unlock completely to lower the
snow thrower to the ground, loosen the lower hex
nut on the lift bracket a few turns and tighten the
upper hex nut. Refer to figure 10 on page 8.
SPIRAL
AUGERS
•
The spiral augers are secured to the auger shaft
with two shear bolts and hex lock 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 21. Two replace-
ment shear bolts and hex lock nuts have been
provided with the snow thrower. For future use
order part number 710-0891 shear bolt and number
43064 hex lock nut.

SKID SHOE, LEVELING SHOE ADJUSTMENT
(The snow thrower must be attached to the tractor for
correct adjustment of the shoes.)
•
The skid shoes regulate the distance the scraper
plate is raised above the plowing surface. They are
mounted on each side of the spiral auger housing.
The leveling shoes help maintain the snow thrower
in a level position. They are mounted just behind
the auger housing.
•
When removing snow from a gravel driveway or an
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 a
smooth blacktop or concrete s_urface, keep the
scraper plate as close to the surface as possible.
•
To adjust the skid shoes, 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 to the desired position and tighten the nuts
securely. Both skid shoes should be the same
height to keep the housing and the scraper plate
level. See figure 22.
•
The skid shoes may be turned to face either in or
out. In order to obtain the lowest setting, where the
scraper blade fully contacts the ground, the skid
shoes must be facing out as shown in figure 22.
•
Before adjusting the leveling shoes, make sure the
skid shoes are properly adjusted. With the snow
thrower in the lowered position, loosen the bolts
which fasten the leveling shoes to the thrower and
adjust the leveling shoes to solidly contact the
ground. Retighten the bolts. See figure 22.
