MOUNTING SNOW THROWER TO TRACTOR
ASSEMBLING THE BELTS
NOTE: The help of another person may be required to
mount the snow thrower to the front of the tractor.
•
Piace the tractor and snow thrower on a fiat, level
surface.
•
Remove the plastic tie from the auger belt and
extend the belt out behind the snow thrower,
making sure the belt remains assembled around
the top of the large auger drive pulley and passing
underneath the two side idler pulleys.
• Align the tractor behind the snow thrower.
•
Remove the attachment pin from the snow thrower.
•
Squeeze the release trigger on the lift handle and
raise the handle out of the locked position, (if the
handle will not release out of the locked position,
refer to the Service and Adjustments section of this
manual.)
•
Grasp the round bar just behind the auger drive
pulley and lift up to align the rear mounting notches
on the snow thrower with the mounting pins on the
tractor. Slide the pins into the notches.
HINT: If you are unable to fit the mounting pins into
the notches, try placing 1" or 2" blocks of wood
under the front skid shoes on the snow thrower.
• Assemble a 3/4" washer and a 1/8" hairpin clip to
each mounting pin.
•
Secure the snow thrower to the tractor using the
attachment pin and 1/8" hairpin clip. Insert the
attachment pin from the left side. See figure 15.
IMPORTANT: The tapered "V" section of the belts must
be seated into the grooves of the V-pulleys.
