will cause the cutting deck to reach their maximum up
travel sooner.
Adjusting the Rear Cutting Deck
The front and rear cutting decks require different mounting
positions. The rear cutting deck has one mounting position
for proper alignment with the sidewinder under frame.
For all heights of cut, mount the rear cutting deck in the rear
mounting holes (Figure 8).

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 9).
3. Beginning with front adjustment, remove the bolt.

4. While supporting the chamber, remove the spacer
(Figure 10).
5. Move the chamber to the desired height-of-cut and
install a spacer into the designated height-of-cut hole
and slot (Figure 10).
6. Position the tapped plate in line with the spacer.
7. Install the bolt finger tight.
8. 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).

between the scraper and roller.
1. Loosen the grease fitting and the mounting screw
(Figure 11).
