1. Cutting-unit kickstand
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
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
