Note: Ensure that the nuts on the back of the bedbar
adjusting screws are not resting on the work surface
(Figure
10).
3. Rotate the reel so that 1 of the blades crosses the
bedknife edge between the first and second bedknife
screw heads located on the right side of the cutting unit.
4. Make an identifying mark on the blade where it crosses
the bedknife edge.
Note: This will make later adjustments easier.
5. Insert a 0.05 mm (0.002 inch) shim between the blade
and the bedknife edge at the point marked in step 4.
6. Turn the right bedbar adjusting screw
you feel light pressure on the shim when sliding it
side-to-side. Remove the shim.
7. For the left side of the cutting unit, slowly rotate the
reel so that the closest blade crosses the bedknife edge
between the first and second screw heads.
8. Repeat steps

contact points on both the left and right sides of the
cutting unit.
10. To obtain light contact between the reel and bedknife,
turn each bedbar adjusting screw clockwise 3 clicks.
Note: Each click on the bedbar adjusting screw moves
the bedknife 0.018 mm (0.0007 inches). Do not over
tighten the adjusting screws.
Turning the adjusting screw clockwise moves the
bedknife edge closer to the reel. Turning the adjusting
screw counterclockwise moves the bedknife edge away
from the reel.
11. Insert a long strip of cutting performance paper (Toro
Part No. 125-5610) between the reel and bedknife,
perpendicular to the bedknife
rotate the reel forward; it should cut the paper; if not,
turn each bedbar adjusting screw clockwise 1 clicks and
repeat this step until it cuts the paper.

Note: If excessive contact/reel drag is evident, backlap,
reface the front of the bedknife, or grind the cutting unit to
achieve the sharp edges needed for precision cutting (Refer
to the Toro Manual for Sharpening Reel and Rotary Mowers, Form
No. 09168SL).
Adjusting the Rear-Roller
Height
Depending on your desired height-of-cut range, you need to
adjust the rear-roller brackets
low or high position:
•
Position the spacer above the sideplate-mounting flange
(factory setting) when the height-of-cut settings range
from 1.5 mm to 6 mm (1/16 inch to 1/4 inch) as shown
in
Figure
13.

•
Position the spacer below the sideplate-mounting flange
when the height-of-cut settings range from 3 mm to 25
mm (1/8 inch to 1 inch) as shown in
1. Sideplate-mounting flange
2. Spacer
1. Raise the rear of the cutting unit and place a block
under the bedknife.
2. Remove the 2 nuts securing each roller bracket and
spacer to each sideplate mounting flange.
3. Lower the roller and screws from the sideplate
mounting flanges and spacers.
