Transport of Reel Mower
Transport the reel mower with the power unit front
hitch fully raised and the left and right lift arms fully
raised. This will aid in protecting cutting units from
contact with obstructions during transport. Damage to
the cutting units may result if transported improperly.
The lift arm locking links can be used to lock the lift
arms in the raised position during transport. If the
power unit is shut off with the lift arm locking links
engaged, the lift arms will remain in the raised posi-
tion. This may be desired during transport, espe-
cially on a trailer or truck, or when in storage.
To engage the lift arm locking links:
1. Park the power unit on a level surface and fully
raise the left and right cutting units.
2. Set the parking brake* and shut off the engine.
3. At the front of the MR740, place the lift arm lock-
ing links over the locking pins.
4. Return to the power unit seat, start the engine, and
lower the left and right cutting units until the locking
links stop the motion of the cutting unit lift arms.
To disengage the lift arm locking links:
1. Park the power unit on a level surface and fully
raise the left and right cutting units.
2. Set the parking brake* and shut off the engine.
3. At the front of the MR740, remove the lift arm
locking links from the locking pins.
4. The lift arms are now ready for operation.
Cutting Height Adjustment
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.
The cutting height is controlled by the position of the
front and rear rollers. The front roller has 4 positions
for coarse adjustment. The rear roller controls the
fine adjustment.
Before performing any procedure to the cut-
ting units, always make sure they are securely
supported, and work in a manner that does not
compromise safety.
1. Determine the required cutting height. Mount the
front roller at the appropriate height range.
2. Adjust the rear roller by loosening the cutting
height adjustment nut.
3. Using a cutting height gauge, set the cutting
height to the desired level.
4. Tighten the cutting height adjustment nut.
Reel Speed
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.
In order to achieve a consistent, high quality cut, it is
very important that the reel speed be matched to the
height of the cut and ground
speed. The table below is
provided as a starting point
for the appropriate reel
speed. Different ground
speed, type of grass, and
conditions may require
adjustment to reach the
correct reel speed for the
application.
1. Determine the reel
speed control lever
position from the chart.
Loosen the retaining nut
