Reel Mowers

This illustrates the characteristics for the bedknife
that are specified in the Toro Reel and Bedknife
Grinding Guidelines, such as Relief Angle and Front
Angle.
When regrinding a bedknife it is important to use the
following procedures:
•
Remove the bedbar and bedknife assembly
from the cutting unit before attempting to
grind a used bedknife.
•
•
Keep the bedknife fastened to the bedbar
when grinding.
When grinding, be careful to not overheat
the bedknife. Remove small amounts of
material with each pass of the grinder.
A lead-in provides a softened entry for the leading
side of the reel blade helix as it approaches the
bedknife. This helps eliminate rifling caused by
heavy contact and vibration. If the bedknife had the
lead-in originally, be sure to put it there when done
grinding the bedknife and reel.

Example specifications for this lead-in for a fairway
mower knife are as shown. These specifications are
only a suggestion. The idea is to get a grind in place
not to spend a lot of time making sure it is exact.
Using a file to make the lead-in is a perfectly
acceptable method. It is important not to make the
lead-in too long or you will notice that there is a
streak left behind at the edge of the cutting unit as
the reel will not cut well in the area of the grind or
may adversely affect the overlap area.
Lead-in
It is also important that the lead-in make a smooth
transition. Be sure to remove any burr that
develops as a result of making the lead-in. The
lead-in will lessen as a result of bedknife wear and
should be redressed with a file at the same time the
ears are removed.
