Replacing the Wheel Belt
Service Interval/Specification
Check all belts after every 50 operating hours or
monthly, whichever occurs first. Look for dirt, wear,
cracks and signs of overheating.
1. Remove hairpin cotter securing brake rod to
brake arm to relax belt idler tension (Fig. 43).
2. Remove bottom and loosen top bolts of shield to
rotate for belt clearance (Fig. 43).
3. Lift belt past idler and off drive pulley (Fig. 43).
4. Raise wheel off ground enough to allow belt
removal.
Note: Ensure that the mud and grass scraper
is adjusted properly and centered in the
pulley grooves (see page 42). The
pointed part of the scraper should be
centered and as deep in the pulley
groove as possible, without rubbing at
any point.
5. Replace drive belt.
6. Secure shield with previously removed bolt and
tighten bolts (Fig. 43).
7. Secure brake rod to brake arm with haripin cotter
(Fig. 43).

(Fig. 44).
6. Slide idler pulley in engine frame to tension
traction belt (Fig. 44).
7. Install the mower belt (Fig. 45).
8. Check the belt guide under the engine frame for
proper adjustment (Fig. 44). The distance
between the belt guide and mower belt should be
1-3/8” (35mm). Adjust as necessary. The
disengaged belt should not drag or fall off pulley
when guides are properly adjusted.
