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 and perfectly flat (Fig. 19).
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.
2. After bedknife grinding is complete, install bedbar to
cutting unit (see Bedbar Installation in this section).
