7.1 Roller Height Adjustment
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.
1. Place the tractor and mower on a level surface
and completely lower the mower to the ground.
2. Shut down the tractor, place the transmission in
park, and set the parking brake before
dismounting.
3. One section at a time, place lifting device
(scissors jack or hydraulic jack) under center of
cutter housing.
4. 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.
5. Use lifting device to reposition cutter housing to
desired cutting height. Align bracket holes with
cutter housing, then reinstall hardware.
6. Lower cutter housing to the ground and remove
lifting device.
7. 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.
