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

MOWER OPERATION (CONT'D)
-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 mower comes 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.
