Prepare Reel For Grinding - Toro Reelmaster 3100-D Service Manual

Prepare Reel for Grinding

Note: Check to make sure reel bearings are in good
condition and properly adjusted before grinding reel.
1. Remove bedbar assembly (see Bedbar Removal
and Installation).
2. Remove front roller and brackets (see Roller Remov-
al and Installation).
Note: Most reel grinders require that the rear roller as-
sembly be mounted to the cutting unit for proper support
in the reel grinder. The rear roller must be parallel to the
reel shaft to remove taper when grinding, or the cutting
unit must be aligned so the grinding wheel will travel par-
allel to the reel shaft. This will result in the 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.
3. Refer to Toro General Service Training Book, Reel
Mower Basics (part no. 09168SL) for reel grinding infor-
mation.
