Bedknife Grinding
Since there can be variations in the mounting surface of
the bedbar, a new bedknife will not be perfectly flat after
it is installed to the bedbar. Because of this, it is neces-
sary to grind a new bedknife after installing it to the bed-
bar. Follow the existing angle that was ground into the
bedknife and grind only enough to make sure the top
surface of the bedknife is true (Fig. 24).
NOTE: When grinding the bedknife, be careful to not
overheat the bedknife. Remove small amounts of mate-
rial with each pass of the grinder. Also, clean and dress
grinding stone often during the grinding process.
1. Use Toro General Service Training Book, Reel Mow-
er Basics (part no. 09168SL) and grinder manufactur-
er's instructions for bedknife grinding information.

cutting unit (see Cutting Unit Operator's Manual).
