Cutter Deck Belt Adjustments - Scag Power Equipment SW Operator's Manual

-NOTE-
When PTO is engaged or (possibly) disengaged,
a squealing sound from the underside of the
machine is normal. It is caused by the electric
clutch plates meshing as the cutter blades come
up to speed. For best equipment life, engage the
clutch with the engine at 3/4 throttle, not under
full load.
WARNING:
To avoid serious bodily injury and damage to the
transmission, the machine must be at a full stop
before shifting between gears or shifting
between forward and reverse.
5. Shift the transmission into gear for the desired
mowing speed.
-NOTE-
Top speed is suggested only for transport!
6. While squeezing the steering brake levers with
both hands, release both neutral latches.
7. When the steering brake levers are released, the
machine will travel straight. To make a right turn,
squeeze the RH lever. To turn left, squeeze the LH
lever.
8. TO STOP, squeeze both levers, lock the neutral
latches, and shift the transmission into neutral.

CUTTER DECK BELT ADJUSTMENTS

1. Remove the belt cover.
2. Adjust the cutter deck drive belt using a belt tension
gauge. Adjust the belt so that the belt moves 1/2"
with 10 pounds of pressure. Adjust the tension by
tightening or loosening the J-bolt nut. (See figure 1)
Due to initial belt stretch and to prevent the belt
from slipping, check this adjustment after the
first 2 hours, 4 hours and 8 hours of operation.
