4.
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 side of the
cutting unit.
Note:
Put an identifying mark on this blade to
make subsequent adjustments easier.
5.
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.
6.
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:
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 hand 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
8
and
through both gaps with slight drag, but one 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 by inserting a long
strip of Toro cutting performance paper between
reel and bedknife, perpendicular to the bedknife
(Figure
10).
Note:
Slowly rotate the reel forward; it should
cut the paper.
9
until the shim can be slid
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
desired height-of-cut range by positioning the
required amount of spacers below the side-plate
mounting flange
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 the spacer to each side-plate mounting
flange.
4.
Lower the roller and the screws from the
side-plate mounting flanges and spacers.
5.
Place the spacers onto the screws on the roller
brackets.
6.
Re-secure the roller bracket and the spacers to
underside of the 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 the bedknife.
Note:
The position of the rear roller to the reel
is controlled by the machining tolerances of the
