4. After installing bedknife to bedbar, grind bedknife.
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 a nd grind only enough to make sure the top
surface of the bedknife is true (Fig. 25).
IMPORTANT: When grinding the bedknife, be care-
ful to not overheat the bedknife. Remove small
amounts of material with each pass of the grinder.
Also, clean and dress grinding stone often during
the grinding process.
1. Use Cutting Unit Operator ’s Manual, Toro General
Service Training Book, Reel Mower Basics (part no.
09168SL) and grinder manufacturer’s instructions for
bedknife grinding information.
2. After grinding bedknife, check lead- in chamfer on
bedknife (see Cutting Unit Operator’s Manual).
3. After bedknife grinding is complete, install bedbar to
cutting unit (see Bedbar Assembly in this section).
NOTE: After grinding the reel and/or bedknife, check
the reel to bedknife contact again after cutting two (2)
fairways. During this initial use, any burrs will be re-
movedfromreel andbedknifewhich maycreateimprop-
er reel to bedknife clearance and thus accelerate wear.
This practice ofre- checking the reel to bedknifecontact
after grinding will extend the longevity of the sharpness
of the edge of the reel and the bedknife.
