Preparing a Reel for Grinding

Note: Check to make sure the reel bearings are in
good condition before grinding the reel. Make sure the
cutting unit frame and roller brackets are true and not
bent or damaged.
1. Remove the bedbar assembly (Bedknife/Bedbar
Disassembly).
2. Remove parts as necessary to mount the cutting
unit into the grinder (e.g., front roller, front roller brack-
ets).
3. Follow the grinder manufacturer's instructions for
set−up and operation of the grinder.
Note: The cutting unit must be aligned so the grinding
wheel will travel parallel to the reel shaft. This will result
in the reel being ground to the desired cylinder shape.
Note: When grinding, be careful to not overheat the
reel blades. Remove small amounts of material with
each pass of the grinder.
