-NOTE-
When the PTO is engaged or (possibly) disen
gaged, 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 1/2
throttle, not under full load.
If you are not familiar with the operation of the
hydrostatic drive and zero turn feature, practice
turning and maneuvering with the hand controls
before engaging the cutter blades.
5. Release the parking brake. Move the speed
adjustment lever to 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 move the speed adjustment lever to
neutral.
9. To move the machine in reverse, squeeze up on
both steering control levers.
