Preparing Reel For Grinding - Toro Reelmaster 5500-D Service Manual

Preparing Reel for Grinding

1. Check to make sure reel bearings are in good condi-
tion and properly adjusted before grinding 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.
