1. Bedbar-adjusting screw
2. Tip the mower to expose the bedknife and the
reel; refer to
Using the Kickstand When Tipping
the Cutting Unit (page 18) .
3. Rotate the reel so that a blade crosses the
bedknife approximately 25 mm (1 inch) in from
the end of the bedknife on the right hand side
of the cutting unit. Putting an identifying mark
on this blade makes subsequent adjustments
easier. Insert the 0.05 mm (0.002 inch) shim
between the marked reel blade and the bedknife
at the point where the blade crosses the
bedknife.
4. Turn the right bedbar adjuster clockwise until
you feel
light pressure (i.e., drag) on the shim,
then back off the bedbar adjuster 2 clicks and
remove the shim.
Note:
Because adjusting 1 side of the cutting
unit affects the other side, the 2 clicks provide
clearance for when the other side is adjusted.
Note:
If starting with a large gap, both sides
should initially be drawn closer by alternately
tightening the right and left sides.
5. Slowly rotate the reel so that the same blade
that you checked on the right side is crossing
the bedknife approximately 25 mm (1 inch) in
from the end of the bedknife on the left side of
the cutting unit.
6. Turn the left bedbar adjuster clockwise until the
shim can be slid through the reel to bedknife
gap with light drag.
7. Return to the right side and adjust as necessary
to get light drag on the shim between the same
blade and bedknife.
8. Repeat steps 6 and 7 until the shim can be slid
through both gaps with slight drag, but 1 click in
on each side prevents the shim from passing
through on both sides. The bedknife is now
parallel to the reel.
Note:
This procedure should not be needed
on daily adjustments, but should be done after
grinding or disassembly.
9. From this position (i.e., 1 click in and shim not
passing through) turn the bedbar adjusters
clockwise 1 click each.
Note:
Each click turned moves the bedknife
0.022 (0.0009 inches). Do not overtighten the
adjusting screws.
10. Test the cutting performance by inserting a long
strip of cutting performance paper (Toro part
number 125-5610) between reel and bedknife,
perpendicular to the bedknife (
Figure 18 ).
Slowly rotate the reel forward; it should cut the
paper.

Note:
If excessive reel drag occurs either
backlap or grind the cutting unit to achieve the
sharp edges needed for precision cutting.
Adjusting the Rear Roller
1. Adjust the rear roller brackets ( Figure 19 ) to the
desired height-of-cut range by positioning the
required amount of spacers below the side-plate
mounting flange (
Figure 19 ) per the HOC Chart.
