Since there can be variations in the mounting surface of the bedbar, it is
necessary to grind the bedknife after installing it to the bedbar. Follow
the bedknife grinding specifications provided; refer to
Bedknife Grinding
Specifications (page 7–14) . Grind only enough material so that the top surface of
the bedknife is true; refer to Figure 105 .

IMPORTANT
Do not grind the bedknife below the service limit; refer to Figure 106 .
Operating the cutting unit with the bedknife below the service limit
may result in poor after-cut appearance and reduce the structural
integrity of the bedknife.

1. Service limit (reel contacts back of bedknife scallop during operation)
2. Service limit (bottom of bedknife scallop reached when grinding)
The bedknife service limit occurs when the reel contacts the back of the bedknife
scallop during operation. Check for reel contact marks at the back of the bedknife
scallop prior to grinding. The bedknife service limit may also occur when the
bottom of the bedknife scallop is reached when grinding the bedknife.
When grinding the bedknife, be careful 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.
