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 and
housing.

• Any bare metal that has become exposed should be

painted or coated with a light oil to prevent rust.

• Store in a dry place.

REMOVING THE SPIRAL AUGER HOUSING

• 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 attachment pin and pull the auger

housing assembly off of the tractor. Refer to ﬁ gure 20
on page 11.

the front skid shoes on the snow thrower. See the
instructions for ﬁ gure 20 on page 11.

PARTS TO REMOVE AT END OF SEASON

• Remove the "V" belt from the engine pulley and the

clutch/idler as sem bly. See ﬁ gure 21 on page 12.

the rear weight tray by re mov ing the two bolts which
fasten it to the tractor draw bar and by loosening the
two bolts fas ten ing the tray's brace arms to the tractor.
