Toro Edge Series Operator's Manual page 14

Note: The adjustment knobs have detents
corresponding to 0.022 mm (0.0009 inch) bedknife
movement for each indexed position.
3. 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 light contact is not maintained, the bedknife/reel
edges will not sufficiently self-sharpen and dull
cutting edges will result after a period of operation.
If excessive contact is maintained, bedknife/reel
wear will be accelerated, uneven wear can result,
and quality of cut may be adversely affected.
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. If a
file is occasionally run across the front edge to remove
this burr, improved cutting can be obtained.
After extended running, a ridge will eventually develop
at both ends of the bedknife. These notches must be
rounded off or filed flush with the cutting edge of the
bedknife to ensure smooth operation.
Note: Over time, the chamfer
to be ground as it is only designed to last 40% of the
bedknife life.
