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).
Important:
Light contact is preferred at all
times. If you do not maintain light contact,
the bedknife/reel edges do not sufficiently
self-sharpen, resulting in dull cutting edges
after a short period of operation. If you
maintain excessive contact, bedknife/reel
wear is accelerated, uneven wear can result,
and the quality of cut may decline.
Note:
As the reel blades continue to run against
the bedknife, a slight burr will appear on the front
cutting edge surface along the full length of the
bedknife. Occasionally run a file across the front
edge to remove this burr to improve cutting.
After extended running, a ridge will eventually
develop at both ends of the bedknife. Round
off these notches or file them flush with the
cutting edge of the bedknife to ensure smooth
operation.

until it does.
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.
1.
Position the cutting unit on a flat, level work
surface.
2.
Tip the cutting unit to expose the bedknife and
reel.
Note:
Ensure that the nuts on the back of the
bedbar adjusting bolts are not resting on the
work surface
(Figure
3.
Rotate the reel so that 1 of the blades crosses
the bedknife edge between the first and second
bedknife bolt 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 makes 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 bolt
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 bolt
heads.
8.
Repeat steps
cutting unit and left bedbar adjusting bolt.
9.
Repeat steps
5
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 bolt
clockwise 3 clicks.
Note:
Each click on the bedbar adjusting bolt
moves the bedknife 0.018 mm (0.0007 inches).
Do not overtighten the adjusting bolts.
Turning the adjusting bolt clockwise moves
the bedknife edge closer to the reel. Turning
the adjusting bolt 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
10), then slowly rotate the reel forward; it should
cut the paper; if not, turn each bedbar adjusting
bolt clockwise 1 clicks and repeat this step until
it cuts the paper.
