-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.

WARNING:

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.
