STORAGE RECOMMENDATIONS
• Lower the snow thrower to the ground and remove
it from the tractor.
• Clean the snow thrower thoroughly. Wash off any
salt deposits which may have dried on the thrower

• Any bare metal that has become exposed should
be painted or coated with a iight oil to prevent rust.
• Store in a dry place.

• Raise the snow thrower to the transport position.
• Release the spring tension from the auger belt idler
arm on the bottom of the clutch/idler assembly.
• Remove the auger drive belt from the clutch/idier
assembly. See figure 18 on page 11.
• Lower the snow thrower to the ground.
•
Remove the attachment pin and puli the auger
housing assembly off of the tractor. Refer to figure
15 on page 10.
HINT: If the auger housing does not remove easily
from the tractor, try placing 1" or 2" blocks of wood
under the front skid shoes on the snow thrower.

PARTS TO REMOVE AT END OF SEASON
• Remove the "V" belt from the engine pulley and the
clutch/idler assembly. See figure 16 on page 10.
• Remove the clutch/idier assembly. (The two hanger

may be left attached to the tractor frame.)
• If a rear mounted attachment is to be used, remove
the rear weight tray by removing the two bolts
which fasten it to the tractor draw bar and by
loosening the two bolts fastening the tray's brace
arms to the tractor. Be sure to retighten the two
bolts and nuts which fastened the brace arms to
the tractor. See figure 19 on page 12.
