4.4. BELT SERVICE

On these mowers, the engine belt transmits power
from engine to drive disc. 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
and
would impair mower performance. The condition of
the engine belt and poly-v belt should be checked
after every 25 hours of mower operation.
