sides 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. one click in and shim not
passing through) turn the bedbar adjusters clockwise
two clicks each.
Note: Each click turned moves the bedknife 0.018
mm (0.0007 inches). Do not over tighten 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 10). Slowly rotate the reel
forward; it should cut the paper.

Note: Should excessive reel drag be evident, it will be
either necessary to backlap or regrind the cutting unit
to achieve the sharp edges needed for precision cutting.
Adjusting the Rear Roller
1. Adjust the rear roller brackets (Figure 11) to the desired
height of cut range by positioning the required amount
of spacers below the side plate mounting flange (Figure
11) per the HOC Chart.

2. Raise rear of cutting unit and place a block under
bedknife.
3. Remove (2) nuts securing each roller bracket and spacer
to each side plate mounting flange.
4. Lower roller and screws from side plate mounting
flanges and spacers.
5. Place spacers onto screws on roller brackets.
6. Re-secure roller bracket and spacers to underside
of side plate mounting flanges with nuts previously
removed.
7. Verify that bedknife to reel contact is correct. Tip
mower to expose front and rear rollers and bedknife.
Note: The position of the rear roller to the reel
is controlled by the machining tolerances of the
assembled components and paralleling is not required.
A limited amount of adjustment is possible by setting
the cutting unit on a surface plate and loosening the
side plate mounting cap screws (Figure 12). Adjust and
retighten cap screws. Torque the cap screws to 37-45
N-m (27-33 ft-lb).
