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 groomer reel, if installed (see Groomer
Reel in the Service and Repairs Section of Chapter 8 –
Groomer (Model 40201) or Chapter 9 – Groomer (Model
40204)).
3. Remove front roller (see Roller Removal in this sec-
tion).
NOTE: Some older 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 the reel being ground to the desired cylinder
shape.
NOTE: When grinding reel, be careful not to overheat
the reel blades. Remove small amounts of material 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. Install front roller (see Roller Installation in this
section).
B. If removed, re–install groomer reel (see Groomer
Reel in the Service and Repairs Section of Chapter 8
– Groomer (Model 40201) or Chapter 9 – Groomer
(Model 40204)).
C. Install bedbar assembly (see Bedbar Installation
in this section).
D. Complete mower set–up and adjustment se-
quence (see Adjustments section of this chapter).
