2. To adjust rear roller proceed as follows:
•
Raise rear of cutting unit and place a block under
bedknife.
•
Remove (2) nuts securing each roller bracket and
spacer to each sideplate mounting flange.
•
Lower roller and screws from sideplate mounting
flanges and spacers.
•
Place spacers onto screws on roller brackets.
•
Re–secure roller bracket and spacers to underside of
sideplate mounting flanges with nuts previously
removed.
3. Verify that bedknife to reel contact is correct. Tip
mower to expose front and rear rollers and bedknife.
Note: The position of the rear roller to the reel is controlled
by the machining tolerances of the assembled components
and paralleling is not required. A limited amount of
adjustment is possible by setting the cutting unit on a
surface plate and loosening the sideplate mounting
capscrews (Fig. 12). Adjust and re–tighten capscrews.

Important
Whenever the cutting unit has to be tipped
to expose bedknife/reel, prop up rear of cutting unit to
make sure nuts on back end of bedbar adjusting screws are
not resting on work surface (Fig. 4).
Adjusting the Height of Cut
Note: For heights of cut greater than .375“, the high height
of cut kit must be installed
1. Loosen locknuts securing height-of-cut arms to cutting
unit side plates (Fig. 13).
