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.
Replacing the Wheel Belt

to relax belt idler tension (Fig. 44).
2. Remove bottom and loosen top bolts of shield to rotate
for belt clearance (Fig. 44).
3. Lift belt past idler and off drive pulley (Fig. 44).
4. Raise wheel off ground enough to allow belt removal.
Note: Make sure that the mud and grass scraper is adjusted
properly and centered in the pulley grooves (see page 35).
The pointed part of the scraper should be centered and as
deep in the pulley groove as possible, without rubbing at
any point.
