For setting consistent cutting unit attitude, Toro
strongly recommends using a two-screw gauge bar,
Toro part no. 98-1852 (Fig. 7). 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 approximate starting 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 first screw to desired height-of-cut. This setting is
from the bar face to the underside of the screw head
(Fig. 7).
2. Using Table 1, set the attitude, “A,” for the second
screw on the gauge bar. This setting is from the bar
face to the end of the screw (Fig. 7).
Note: Rotate the cutting unit backward to gain access
to reel and bedknife.
3. Set the front height-of-cut rod height,“B,” using the
dimension given in Table 1. This measurement is
between the top surface of the height-of-cut rod and
top cone nut (Fig. 8).
4. Set the rear support casting in either the top or bottom
location as indicated in Table 1. Set the rear
height-of-cut rod height .100” (3 mm) less than the
dimension given in Table 1 which will create a gap
between the rear roller and the gauge bar (Fig. 8).

Note: Place gauge bar across front and rear rollers.
The first screw head should fit snugly over edge of
bedknife and the end of second screw should contact
bottom of bedknife (Fig. 8). If there is a gap between
the front roller and the gauge bar or you can not put
the gauge bar on, adjust the front roller until: (1) first
(height-of-cut) screw fits snugly over bedknife, (2)
second screw just contacts bedknife, and (3) gauge bar
touches front roller. Verify front roller (attitude) at
each end of the bedknife.
Note: At this time, there should be a small gap
between the rear roller and gauge bar.
