Preparing a Reel for Grinding
Note: Check to make sure the reel bearings are in
good condition before grinding a reel.
1. Remove bedbar assembly (see Bedbar Removal
and Installation).
2. Remove parts as necessary to mount cutting unit
into grinder (e.g., front roller, front roller brackets).
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 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 additional reel
grinding information.
4. After completing the grinding process:
A. Install parts removed to mount cutting unit into
grinder.
B. Install bedbar assembly (see Bedbar Removal
and Installation).
C. Complete cutting unit set--up and adjustment se-
quence (see Adjustments section).
