Making Adjustments

Adjusting the Bedknife to the Reel
Use this procedure to set the bedknife to the reel and to check
the condition of the reel and bedknife and their interaction.
After completing this procedure, always test the cutting
unit performance under your field conditions. You may
need to make further adjustments to obtain optimal cutting
performance.
Important: Do not overtighten the bedknife to the reel
or you will damage it.
•
After backlapping the cutting unit or grinding the reel, you
may need to mow with the cutting unit for a few minutes
and then perform this procedure to adjust the bedknife to
the reel as the reel and bedknife adjust to each other.
•
You may need additional adjustments if the turf is
extremely dense or your cutting height is very low.
You will need the following tools to complete this procedure:
•
Shim (0.002 inch)
•
Cutting performance paper
1. Position the cutting unit on a flat, level work surface.
2. Turn the bedbar adjusting screws counterclockwise to
ensure that the bedbar does not contact the reel

3. Tip the cutting unit to expose the bedknife and reel.
Important: Make sure that the nuts on the back
end of the bedbar adjusting screws are not resting
on the work surface

(Figure 9).
1. Kickstand
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/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
(Figure
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
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.
