Preparing Reel for Regrinding
1. Check to make s ure reel bearings are in good condi-
tion and properly adjusted before regrinding the reel.
Make sure the cutting unit frame and roller brackets are
true and not bent or damaged from impacts with trees,
posts or cart path edges.
2. Remove bedbar assembly.
3. Remove parts as necessary to mount the cutting unit
in the grinder (e.g. front roller, brackets). Follow the
grinding equipment manufacturers instructions for
mounting the cutting unit.
Note: The cutting unit must be aligned so the grinding
wheel will travel parallel to the reel shaft. This will result
in the the reel being ground to the desired cylinder
shape.
Note: When regrinding, be careful to not overheat the
reel blades. Remove small amounts of material with
each pass of the grinder.
4. After completing the regrinding process, do a c om-
plete set-up and adjustment procedure.
