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 two 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 hand 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 both 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., 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
mm (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 No.
125-5610) between reel and bedknife, perpendicular
to the bedknife (Figure
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
height-of-cut range by positioning the required amount
of spacers below the side-plate mounting flange
13) per the HOC Chart.
1. Spacer
2. Roller bracket
2. Raise the rear of the cutting unit and place a block
under the bedknife.
3. Remove the 2 nuts securing each roller bracket and
spacer to each side-plate mounting flange.
4. Lower the roller and screws from the side-plate
mounting flanges and spacers.
5. Place the spacers onto the screws on the roller brackets.
6. Secure the roller bracket and spacers to underside of
side plate mounting flanges with the nuts previously
removed.
7. Verify that the bedknife-to-reel contact is correct. Tip
the mower to expose the 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; therefore, 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
and tighten the cap screws. Torque the cap screws to
37 to 45 N-m (27 to 33 ft-lb).
