Checking or Adjusting Attitude for Used
Cutting Units
Note: As a starting point for adjusting cutting
unit attitude, the cutting unit may be
set up using the dimensions from
Table 1. However, because of wear on
the bedknife and reel, the following
procedure must be used to ensure the
correct attitude setting.
1. Rotate cutting unit backward to gain access to reel and
bedknife.
2. Place an angle indicator, Toro Part No. 99–3503, on
the bedknife and record the bedknife angle (Fig. 9).

3. Using a two-screw gauge bar, Toro Part No. 98-1852,
set first screw to desired height-of-cut.
4. Place the gauge bar across front and rear rollers. The
first screw head needs to fit snugly over edge of the
bedknife,while the gauge bar contacts the front roller
(Fig. 10).
Note: The rear roller does not have to contact the
gauge bar.
5. Adjust second screw to contact bedknife. Move rear
roller up, if needed.
6. Place an angle indicator on the gauge bar and record
the gauge bar angle (Fig. 10).

7. Adjust the front roller to your desired cutting unit
attitude:
Bedknife Angle (step 2)
– Gauge Bar Angle (step 6)
= Cutting Unit Attitude (degrees)
Note: Moving the front roller down will
decrease your cutting unit attitude,
while moving the front roller up will
increase cutting unit attitude (Fig. 10).
