Adjusting the Bedknife after
Grinding, Backlapping, or
Disassembly
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.
Note:
For eFlex cutting units, the reel-to-bedknife
contact has a significant impact on energy
consumption. Very light contact is best for cutting
performance and battery consumption.
1.
Shut off the traction unit.
2.
Access the cutting unit; refer to
Cutting Unit (page
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 (Toro Part
No. 140-5531) 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
bedknife, perpendicular to the bedknife

until there is light pressure
(Figure
9), 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 or reel drag is evident,
you may 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).
