4.4 BELT SERVICE

WARNING

On self-propelled 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 would impair

mower performance. The condition of the engine belt

and poly-v belt should be checked after every 25 hours

of mower operation.

DO NOT attempt any maintenance, adjustments or

service with engine and blade running. STOP engine

and blade. Disconnect spark plug wire and secure

away from spark plug. Engine and components are

HOT. Avoid serious burns, allow sufficient time for

all components to cool.
