NOTE: An
a
dditional person's help may be required to
mount the snow thrower to the front of the tractor.
•
Place the tractor and snow thrower on a flat, level
surface so that the tractor can be rolled forward to
attach the snow blower.
•
Remove the Attachment Pin from the snow thrower.
•
Extend the belt out behind the snow thrower,
making sure the belt is still looped over the top of
the large drive pulley and underneath the two idler
pulleys. The "V" side of the belt must be seated in
the grooves of all three pulleys.
•
Roll the tractor up behind the snow thrower, center-
ing it between the snow thrower's mounting plates.
•
Raise the rear of the snow thrower by lifting up on
the lift handle until the notches in the mounting
plates align with the shoulder bolts in the tractor's
side plates. Guide the bolts into the notches.
•
To ease the assembly of the auger drive belt, delay
the installation of the attachment pin shown in
figure 29 until you have assembled the belt as
instructed for figures 30 and 31.
ATTACHING SNOW THROWER TO TRACTOR INSTALLING THE AUGER BELT

The auger belt comes preassembled to the pulleys
on the snow thrower housing. Make sure the belt
passes over the top of the auger pulley and then
twists 1/4 turn to pass underneath each side idler
pulley. The "V" side of the belt must mate with the
grooves of the pulleys. See figure 30.
