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 power unit and reel mower on a level sur-
face, with the engine shut off, and all fluids cold.
2. Perform a visual inspection of the power unit and
reel mower. Look for loose or missing hardware,
damaged components, or signs of wear.
3. Inspect hydraulic hoses, hydraulic fittings, and
fuel lines to ensure tight, leak free connections.
4. 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.
5. Check reel mower hydraulic oil level. Refer to "ser-
vice - hydraulic system" section of this manual.
6. Inspect the reel mower cutting edges. Reel
blades should be free of nicks and bends. The
bed knife should be sharp and securely fas-
tened. Service as required.
7. Check blade adjustment of the reel to the bed
knife. Refer to blade adjustment later in this sec-
tion. If back lapping is required, refer to "back
lapping" in the service section.
8. Test the power unit's operator safety interlock
system.*

Attaching

1. Drive the power unit slowly forward into the hitch
arms of the reel mower. Align the lift arms of the
power unit with the reel mower hitch arms by
raising 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 over the outside groove
of the PTO drive pulley on the power unit. Ensure
the belt is properly seated in each pulley.
5. Engage the PTO spring tension lever*.
6. Wipe hose ends clean, and connect to the power
unit's hydraulic quick couplers.
7. Engage the weight transfer system*.
NOTE: Full engagement of the weight transfer

Mowing and Operating Procedure

Perform daily inspection and confirm the reel speed
and cutting heights are set properly. Set the power
unit's weight transfer system to the desired setting.
With the power unit engine running between 2,000
and 3,000 RPM, engage the PTO switch. Adjust the
throttle to the desired engine rpm. (If a good cut can
be maintained and there is sufficient power, a reduced
engine speed will result in improved fuel economy and
reduction in wear and tear on the equipment.)
Lower the cutting units to the ground and place the
power unit's primary and secondary S.D.L.A. control
levers in the float position by pushing them to the
right until the detent engages. The levers will stay in
this position until intentionally removed.
Begin forward motion in the desired path of mowing.
Avoid obstacles, removing debris as necessary.
Mowing in a back and forth manner will create a
striping pattern in the grass. The full length roller
behind each cutting unit rolls the grass in the direc-
tion of travel.
Lift the cutting units when the edge of the mowing
area is reached. Turn the power unit and mower
around and align for the next pass.
* Refer to power unit operator's manual for operation of
power unit controls.

is recommended for most mowing applications.
Adjust the amount of weight transfer as required.
