Perform this procedure even if the quality of cut
is acceptable.
1.
Slowly rotate the reel in a reverse direction,
listening for reel-to-bedknife contact.
Note:
The adjustment knobs have detents
corresponding to 0.018 mm (0.0007 inch)
bedknife movement for each indexed position.
Refer to
Adjusting the Bedknife to the Reel
(page
8).
2.
Test the cutting performance by inserting
a long strip of cutting performance paper
(Part No.125-5610) between the reel and the
bedknife, perpendicular to the bedknife
7). Slowly rotate the reel forward; it should cut
the paper.
Note:
If excessive contact/reel drag is evident,
either 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 and reel edges will
not sufficiently self-sharpen and will dull
after a period of operation. If you maintain
excessive contact, the bedknife and reel will
wear quicker, wear unevenly, and the quality
of cut may be adversely affected.
Note:
After extended running, a ridge will
eventually develop at both ends of the bedknife.
Round off or file these notches flush with the
cutting edge of the bedknife to ensure smooth
operation.
Note:
Over time, you will need to grind the
chamfer
(Figure

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:
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 0.05 mm (0.002 inch) (Part No. 125-5611)
•
Cutting performance paper (Part No. 125-5610)
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
