CAUTION: Before servicing or adjusting
the snow thrower, shut off the engine,
remove the spark plug wire(s), set the
parking brake and remove the key from
the tractor ignition.
REPLACING AUGER BELT
• Release spring tension from the upper drive belt.
• Lower the snow thrower to the ground.
• Remove the attachment pin.
• Lock the snow thrower's lift handle in the down
position to decrease auger belt tension.
• Release spring tension from the lower auger belt.
• Remove the auger drive belt from the clutch/idler
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 22 on page 12.
Assemble the belt onto the clutch/idler assembly.
Refer to figures 23 and 24 on page 12.
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, 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 29.
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 10.
• 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 10.
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 30. Two replace-
ment shear bolts and hex lock nuts have been
provided with the snow thrower. For future use
order part number 710-0890A shear bolt and
number 43064 hex lock nut.
