Daily Inspection

Always set the parking brake, shut off the power
unit engine, remove the ignition key, and ensure
all moving parts have stopped before checking
mower deck or blade condition, or attempting
any repair or adjustment.
1. Park the power unit and mower deck on a level
surface, with the engine shut off and all fluids cold.
2. Perform a visual inspection of the power unit and
mower deck. Look for loose or missing hard-
ware, damaged components, or signs of wear.
Inspect hydraulic hoses, hydraulic fittings, and
fuel lines to ensure tight, leak free connections.
3. Refer to the power unit operator's manual.
Check the power unit's engine oil, hydraulic oil,
cooling system, tire pressure, and fuel level. Add
fluid or service system as required.
4. Inspect the drive belts and mower blades. Belts
should be in good condition. Blades should be
sharp and securely fastened. Service as required.
5. Refer to the power unit operator's manual. Test
the power unit's operator safety interlock system.

Attaching

1. Drive the power unit slowly forward into the hitch
arms of the mower deck. Align the lift arms of the
power unit with the mower hitch arms by rais-
ing or lowering the front hitch and complete the
engagement.
2. Once completely engaged, close the front hitch
locking lever.*
3. Engage the parking brake* and shut off the
engine.
4. Place the attachment belt onto the PTO drive
pulley on the power unit. Ensure the deck belt is
properly routed and engaged in each pulley.
5. Engage the main belt tensioner. NOTE: if deck
is raised to the top position, the deck shield will
interfere with the belt tensioner.
6. Always check to ensure the deck belt is properly
located in each pulley groove before attempting
to operate.

Detaching

1. Park the power unit on a level surface and set
the parking brake.*
2. Lower the mower deck to the ground.
3. Shut off power unit engine.

GENERAL OPERATION

4. Raise the mower deck to the highest cutting
5. Disengage the main belt tensioner.
6. Remove the attachment belt from the PTO drive
7. Disengage the hitch locking lever.*
8. Restart the power unit and slowly back away

Mowing and Operating Procedure

Before operation, perform daily inspection and
confirm that the cutting height is set properly. Set the
power unit's weight transfer system* (if equipped) to
the desired setting.
With the power unit engine running between 2,000
and 2,500 RPM, engage the PTO switch. Adjust the
throttle to the desired engine RPM.
Lower the mower deck to the ground and place
the power unit's primary S.D.L.A. control lever in
the float position by pushing it to the right until the
detent engages. The lever will stay in this position
until intentionally removed.
Begin forward motion in the desired path of mowing.
Avoid obstacles, removing debris as necessary.
A stripe pattern in the grass is produced when each
mowing pass is done in the opposite direction of
the pass beside it. This look is enhanced by the
full length roller, which helps to roll the grass in the
direction of travel.
Lift the mower deck when the edge of the mowing
area is reached. Turn the power unit and mower
around and align for the next pass.
Blades should be kept in good condition. Sharp
blades will increase efficiency and improve the
quality of cut.
Mowing in wet conditions may result in a build up of
clippings under the deck. Periodic checking should be
done by the operator to determine if the deck should
be cleaned. The deck should also be checked any-
time mowing performance seems to be reduced.
