Adjusting the Bedknife to the
Reel
Note: Use this procedure for initial set up and after grinding,
backlapping, or disassembly. It is not intended as a daily
adjustment.
1. Position the cutting unit on a flat, level work surface.
2. Tip the cutting unit to expose the bedknife and the
reel. Make sure the nuts or the back of the bedbar
adjusting screws are not resting on the work
surface (Figure 10).

3. Rotate the reel so that a blade crosses the bedknife edge
between the first and second bedknife screw heads on
the right side of the cutting unit.
4. Put an identifying mark on the blade where it
crosses the bedknife edge; this will make subsequent
adjustments easier.
5. Insert the .05 mm (0.002 inch) shim between the
marked blade and the bedknife edge at the point where
the marked blade crosses the bedknife edge.

6. Turn the right bedbar adjusting screw until you feel
light pressure (i.e. drag) on the shim by sliding it
side-to-side. Remove the shim.
7. For the left side of the cutting unit, slowly rotate the
reel so that the closest blade crosses the bedknife edge
between the first and second screw heads.
8. Repeat steps 4 through 6 for the left side of the cutting
unit and left bedbar adjusting screw.
9. Repeat steps 5 and 6 until light drag is achieved on
both the right and left sides of the cutting unit utilizing
the same contact points.
The bedknife is now parallel to the reel.
10. To obtain light contact between the reel and bedknife,
turn each bedbar adjusting screw clockwise 3 clicks.
Note: Each click turned on the bedbar adjusting
screw moves the bedknife 0.018 mm (0.0007 inches).
Clockwise rotation moves the bedknife edge closer
to the reel and counterclockwise rotation moves the
bedknife edge away from the reel.
11. Test the cutting performance by inserting a long strip
of cutting performance paper (Toro part number
125-5610) between the reel and bedknife, perpendicular
to the bedknife (Figure 11). Slowly rotate the reel
forward; it should cut paper

Note: If excessive contact/reel drag is evident it will
be either necessary to backlap, reface the front of the
bedknife, or regrind the cutting unit to achieve the
sharp edges needed for precision cutting (Refer to the
Toro Manual for Sharpening Reel and Rotary Mowers,
Form No. 09168SL).
Adjusting the Rear Roller
1. Adjust the rear roller brackets (Figure 12 or Figure 13)
to the low or high position depending on the desired
height of cut range.
