Mowing and Operating Procedure

ATTENTION
If an object is struck or the mower develops an
unusual vibration during operation, shut off the PTO
immediately. Refer to the Checking Rotor for Vibra-
tion section and make all necessary repairs before
resuming operation.
If a cutting knife is missing or significantly dam-
aged, STOP! Cease operation until the cutting knife
is replaced. Refer to the Cutting Knife Inspection and
Replacement section for instructions on replace-
ment and maintaining rotor balance.
Before operation, perform the daily inspection and
confirm the cutting height and the power unit weight
transfer system are set properly.
Inspect the mowing area and remove rocks, sticks,
and any other objects that could be thrown from the
machine or become entangled in blades or rotor.
Lower the mower deck to the ground and place the
power unit's SDLA lever in the float position by push-
ing it to the right until the detent engages. The lever
will stay in this position until intentionally removed.
With the power unit engine running between 2,000
and 3,000 RPM, engage the PTO switch, then adjust the
throttle to the desired engine RPM.
Begin forward motion in the desired mowing path.
Avoid obstacles and remove debris as necessary. To
maintain cut quality, adjust your ground speed for the
conditions. Decrease the ground speed as the load on
the flail mower increases. Increase the ground speed
when the load on the flail mower decreases. When the
edge of the mowing area is reached, turn around and
align the mower for the next pass.
Mowing in a back and forth pattern, where each mow-
ing pass in made in the opposite direction of the pass
next to it, will create a stripe pattern in the grass. The
full length rear roller rolls the grass in the direction of
travel to further enhance the stripe effect.
When mowing is complete, slow the engine speed to
2,500 RPM or lower before disengaging the PTO switch.
GENERAL OPERATION

Transport of Attachment

Transport the attachment with the power unit front
hitch and attachment fully raised to reduce wear of
the equipment. Travel slowly when transporting over
undulating and rough surfaces to maintain control of
the power unit and to reduce the shock to the power
unit and the attachment. Always disengage the power
unit PTO before transporting the attachment.
