CARE AND MAINTENANCE - 4000 SERIES MODELS

BELT TENSION:

ENGINE TO MOWER DECK BELT: P/N6111

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 el ectric 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.
