Belt Service
On self-propelled mowers, the engine belt transmits power
from the engine to the transmission that powers the rear
wheels. Should the belt become worn, it could cause slip-
page, which would impair mower performance. The condi-
tion of the engine belt should be checked after every 25
hours of mower operation.
