98-1852 (Fig. 10). The first screw is set for height of cut,
and the second screw is set for cutting unit attitude. The
second screw setting is an easy method of transferring
cutting unit attitude to all cutting units on a machine.

SETTING ATTITUDE FOR NEW CUTTING
UNITS:
Table 1 lists dimensions for setting up a new cutting unit
with attitudes of 2, 4, 6 and 8 degrees.
NOTE: The second screw setting will change
throughout the life of the bedknife and reel due to wear
even if the height of cut is not changed. Therefore, after
initial set up use Checking and Adjusting Attitude for
Used Cutting Unit procedure.
1.
Using a two-screw gauge bar, Toro part no. 98-
1852, set the first screw to the desired height of cut.
This setting is from the bar face to the underside of
the screw head (Fig. 10).
2.
Set the front bracket height "B" using the
approximate dimension given by Table 1. This
measurement is between the bottom surface of the
middle casting and the top surface of the rod casting
(Fig. 11).

"B"
3.
Set the rear support bracket and side plate using the
approximate dimensions given by Table 1. The rear
support bracket is either in the top or bottom
location, and the side plate location can be in holes
1 through 4, with 1 being the top hole (Fig. 12).

4.
With the cutting unit rotated vertical, place gauge
bar across front and rear rollers. The first screw
head should fit snugly over the edge of the
bedknife. The end of the second screw should
contact the bottom of the bedknife (Fig. 13). If there
is a gap between the front roller and the gauge bar,
lower the front roller until it contacts the gauge bar.
Verify front roller (attitude) at each end of the
bedknife.
NOTE: At this time leave a small gap between the
rear roller and gauge bar.
