OPERATION
7.1 Roller Height Adjustment
1. The mower’s cutting height is set by positioning
the roller assembly for each mower section.
Each section must be set at the same height to
ensure an even cut across the entire width of
the mower.
2. Place the tractor and mower on a level surface
and completely lower the mower to the ground.
3. Shut down the tractor, place the transmission in
park, and set the parking brake before
dismounting.
4. One section at a time, place lifting device
(scissors jack or hydraulic jack) under center of
cutter housing.
5. Remove hex nuts, washers and carriage bolts
from bracket at each end of roller. Make certain
that roller bracket is free to move once the
fasteners are removed. A stuck roller could
drop unexpectedly and cause injury.
6. Use lifting device to reposition cutter housing to
desired cutting height. Align bracket holes with
cutter housing, then reinstall hardware.
7. Lower cutter housing to the ground and remove
lifting device.
8. Set cutting height according to procedures
above for remaining two cutter sections. Make
sure that all three rollers are set at the same
height to ensure a even cut across the entire
width of the mower.
Hydraulic Cylinder Priming
Hydraulic Cylinders must be filled with hydraulic oil before releasing the wing transport locks to lower the
mower. Hydraulic cylinders and lines are filled by holding the valve control levers in the raised position until the
cylinders fully extend then place the control lever in the float position. Repeat the process several more times
to ensure wings are entirely supported by the hydraulic cylinders before releasing the transport locks and
lowering the mower.
