4.4. BELT SERVICE
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 en gine belt and po ly-v belt shoul d be
checked after every 25 hours of mower operation.
