Belt Service

On self-propelled mowers, the engine belt (A, Figure 35)
transmits power from the engine pulley (B) to the drive disc
(C). The drive disc powers the poly-v belt, which engages the
transmission that powers the rear wheels. Should these belts
become worn, they could cause slippage, which would
impair mower performance. The condition of the engine belt
and poly-v belt should be checked after every 25 hours of
mower operation.
Engine Drive Belt Replacement (Stretch Type
Belts)
1. Empty the fuel tank.
2. Note the belt routing (Figure 35). There is no idler
pulley on these models to disconnect.
