Adjusting the Bedknife to the Reel
Use this procedure during initial cutting-unit setup and
after grinding, backlapping, or disassembling the reel.
This is not a daily adjustment.
Note:
This procedure can be performed with the
cutting unit installed to the traction unit.
1.
Shut off the traction-unit engine.
2.
Access the cutting unit by lowering the
traction-unit handle to the ground
3.
Rotate the reel so that 1 of the blades crosses
the bedknife edge between the first and second
bedknife screw heads located on the right side
of the cutting unit.
4.
Make an identifying mark on the blade where it
crosses the bedknife edge.
Note:
This will make later adjustments easier.
5.
Insert a 0.05 mm (0.002 inch) shim between the
blade and the bedknife edge at the point marked
in step 4.
6.
Turn the right bedbar adjusting screw
until you feel light pressure on the shim when
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
cutting unit and left bedbar adjusting screw.
9.
Repeat steps
5
and
at the contact points on both the left and right
sides of the cutting unit.
10.
To obtain light contact between the reel and
bedknife, turn each bedbar adjusting screw
clockwise 3 clicks.
Note:
Each click on the bedbar adjusting screw
moves the bedknife 0.018 mm (0.0007 inches).
Do not over tighten the adjusting screws.
Turning the adjusting screw clockwise moves
the bedknife edge closer to the reel. Turning the
adjusting screw counterclockwise moves the
bedknife edge away from the reel.
11.
Insert a long strip of cutting performance paper
(Toro Part No. 125-5610) between the reel and
(Figure

for the left side of the

until there is light pressure
bedknife, perpendicular to the bedknife
10), then slowly rotate the reel forward; it should
cut the paper; if not, turn each bedbar adjusting
screw clockwise 1 clicks and repeat this step
until it cuts the paper.

Note:
If excessive contact/reel drag is evident,
backlap, reface the front of the bedknife, or grind
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).
