Note:
Adjusting 1 side of the cutting unit affects
the other side, the 2 clicks will 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.
7.
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.
8.
Turn the left bedbar adjuster clockwise until the
shim can be slid through the reel to bedknife
gap with light drag.
9.
Return to the right side and adjust as necessary
to get light drag on the shim between the same
blade and bedknife.
10.
Repeat steps
and
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.
Note:
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.
11.
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 inch).
Do not overtighten
the adjusting screws.
12.
Test the cutting performance; refer to
the Cutting Unit (page 8)

Adjusting the Rear Roller
1.
Adjust the rear roller brackets (
) to the
desired height-of-cut range by positioning the
required amount of spacers below the side-plate
mounting flange (
) per the HOC Chart.

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 (
). Adjust and tighten the cap
screws. Torque the cap screws to 37 to 45 N·m
(27 to 33 ft-lb).
