Belt Replacement:
If belts become excessively worn or cracked, install a new belt. This is done most
easily with the deck removed from the tractor.
Main Deck Belt Replacement:
1. Remove old belt. Note that one belt loop must surround the left hitch arm.
Remove left hitch arm for access.
2. Install the replacement belt as shown in the diagram below. Begin by placing one
belt loop around the left hitch arm. Place belt into the idler pulley and then the drive
pulley. Take the belt to the right double groove pulley rotating the belt 1/4 turn into
the pulley groove.
3. Once around the pulley, follow the diagram to the other pulleys. Note: The
“V” shape of the belt should fit nicely into each pulley groove. Belt twist
should never exceed 1/4 turn.
4. Tension the belt by tightening the idler adjustment rod. The spring loops should
have approximately .05 inches between them.
Note: a rule of thumb is to slip a paper clip between them.
Right Belt Replacement:
Remove main deck belt. Install replacement belt as shown. Reinstall the main deck
belt.
Drive Belt Replacement:
Remove mower from tractor. Remove pulley cover, replace belt over pulley and left
hitch arm. Reinstall cover.
