Preparing 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 in
this section).
2. Remove front roller (see Roller Removal in this sec-
tion).
3. Remove grooming reel, if installed (see Grooming
Reel in the Service and Repairs Section of Chapter 8 –
Groomer).
NOTE: Some grinding machines may require that the
cutting reel be removed from the mower.
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 the cutting reel, be careful to not
overheat the reel blades. Remove small amounts of ma-
terial with each pass of the grinder.
4. Grind cutting reel (refer to TORO Sharpening Reel
and Rotary Mowers Manual, Form No. 80-300 PT).
5. After completing grinding process:
A. If equipped, install grooming reel (see Grooming
Reel in the Service and Repairs Section of Chapter 8
– Groomer).
B. Install front roller (see Roller Installation in this
section).
C. Install bedbar assembly (see Bedbar Installation
in this section).
D. Complete mower set–up and adjustment se-
quence.
