4. Grind the top face and front face as described in
the preceding paragraphs.
NOTE:
The bedknife end at which the reel first makes
contact is called the leading end. A beveled cor-
ner (dub) is ground on this end. It is important that
the dub be maintained throughout the life of the
bedknife. The dub provides an entrance ramp for
the reel blade on to the bedknife. If the dub is
worn or ground away and not replaced, the reel
blade could hook the corner of the bedknife as it
begins contact.
5. After grinding the bedknife, examine the dub. If,
through grinding, it has become smaller tank 0.18
in (1.6 mm) hand grind or file the surface to the
specified dimensions (Figure 12E-7).
6. Use a fine hone or block of wood to clean up
ground material and any small burrs after grinding
the bedknife.
