CARE AND MAINTENANCE
BELTS:
Check belts every 50 hours. Replace any belts found to be in
poor condition.
BELT TENSION:
Transaxle Drive Belt: P/N 7650
No adjustment required.
Engine to Mower Deck Belt: P/N 7725
No adjustment required. Correct belt tension is maintained
through a fixed engine location and a spring loaded idler
system. A pulsing movement of the belt idler will be observed
both during engagement of the electric blade clutch and actual
operation of the mower deck.
Note: Engagement of the electric blade clutch switch may
produce a sharp high pitched chirp or squeal as the belt
tension loading is absorbed by the idler system. This is
normal and not a sign of failure.
Mower Deck Serpentine Belt: P/N 6109
Refer to illustration for adjustment procedure.
