-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 cutter
blades come up to speed. For best equipment
life, engage the clutch with the engine at 3/4
throttle, not under full load.
If you are not familiar with the operation of the
hydrostatic drive, practice turning and
maneuvering before engaging the cutter blades.
5. Release the parking brake. Depress the right foot
pedal at the toe end to drive forward (See Figure 1)
or depress the pedal at the heel end to drive in
reverse. (See Figure 2)
-NOTE-
The left side operator presence pedal must be
depressed for operation.

6. When driving over curbs, disengage the cutter blades
and raise the cutter deck to clear the curb. Drive
forward over the curb. After the curb is clear, lower
the cutter deck back to normal operating position.
Be sure to leave slack in the cable after lowering the
cutter deck.
7. To "freewheel" or move the machine around without
the engine running, rotate the dump valve lever
located on the left rear of the engine deck to the
freewheel position (See Figure 3). The lever must be
returned to the drive position to operate the machine.
