Note: If excessive contact/reel drag is evident it will
be either necessary to backlap, reface the front of the
bedknife, or regrind 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, the chamfer (Figure 21) will need to
be reground as it is only designed to last 40% of the
bedknife life.
Figure 21
Note: Do not make the lead-in chamfer too large as
it may cause turf tufting.
