CARE AND MAINTENANCE
BELTS
Check belts every 50 hours. Replace any belts showing
signs of wear or cracking.
BELT TENSION
Transmission Drive Belt - P/N 539 120772
No adjustment necessary.
Engine to Mower Deck Belt
36" P/N 539 117811
42" P/N 539 122734
44" P/N 539 118156
To adjust the tension of
the mower deck drive
belt, turn adjuster nut on
threaded eyebolt.
Turning nut to the left
will loosen the belt, see
Fig 10. Idler arm, spring
and eyebolt location/
appearance will vary on
some models.
NOTE: Engaging the
blade clutch 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.
Belt deflection or movement should be approximately ¼"
when measured at mid-point between pulleys.
Periodically inspect both belt and idler systems.
