PARTS TO REMOVE AT END OF SEASON
• Remove the clutch/idler assembly. (The two hanger
brackets and the two shoulder bolts may be left
attached to the tractor frame.)
• Remove the drive belt from the engine pulley.
• If you replaced the engine pulley keeper on a manual
attachment clutch tractor, reinstall the tractor's original
engine pulley keeper. See figure 33 on page 16 or
figure 39 on page 18.
• If you have a rod operated attachment clutch, remove
the engagement rod from the tractor's clutch arm. See
figure 29 on page 15.

the rear weight tray, leaving the bolts that you installed
in the sides of the tractor draw bar. Retighten the
bolts.

the side plates from the tractor. Be sure to assemble
bolts back into the empty holes in the tractor frame.

• Lower the snow thrower to the ground.
• Remove the snow thrower from the tractor.
• Clean the snow thrower thoroughly. Wash off any salt
deposit which may have dried on the thrower and
