Adjusting the Height-of-Cut
No Parts Required
Procedure
Important:
This cutting deck often cuts approximately
6 mm (1/4 inch) lower than a reel cutting unit with the
same bench setting. It may be necessary to have these
rotary cutting deck’s bench set 6 mm (1/4 inch) above
that of reels cutting in the same area.
Important:
Access to the rear cutting units is greatly
improved by removing the cutting unit from the tractor.
If the unit is equipped with a Sidewinder®, sidewind the
cutting units to the right, remove the rear cutting unit,
and slide it out to the right side.
1.
Lower the cutting deck to the ground, stop the engine,
and remove the key from ignition switch.
2.
Loosen the bolt securing each height-of-cut bracket to
the height-of-cut plate (front and each side) (
Figure 7
).
3.
Beginning with front adjustment, remove the bolt.

Repeat steps 4-7 for each side adjustment.
9.
Tighten all three bolts to 41 N-m (30 ft-lb). Always
tighten the front bolt first.
Note:
Adjustments of more than 3.8 cm (1-1/2
inches) may require temporary assembly to an
intermediate height to prevent binding (e.g. changing
from 3.1 to 7 cm (1.25 to 2.75 inch) height-of-cut).
