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.
