Prepare Reel for Grinding
The front roller may have to be removed so that the reel
can be sharpened.
Note: Check to make sure reel bearings are in good
condition and properly adjusted before grinding reel.
IMPORTANT: Some reel grinders may require that
the rear roller assembly be mounted to the cutting
unit for proper support in the reel grinder.
1. Remove locknuts and cap screws securing the front
roller brackets to the sideplates at both ends of the cut-
ting unit (Fig. 11).
2. Remove front roller assembly from the cutting unit by
pulling evenly on both sides.
3. For proper grinding of reel, grind in accordance with
procedures in the Toro Sharpening Reel and Rotary
Mowers Book, Part No. 80300SL.
Note: Most reel grinders require that the rear roller
assembly be mounted to the cutting unit for proper sup-
port 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 parallel to the reel shaft. This will result in the the
reel being ground to the desired cylinder shape.
IMPORTANT: After grinding operation is complete,
reassemble cutting unit, check bearing adjustment
and adjust top shield and bar; refer to sections on
Adjusting Shield Height and Adjust Top Bar. Back
lap the cutting unit to complete sharpening opera-
tion. To assure proper alignment of the rear roller in
the roller brackets, make sure roller moves freely
within brackets before tightening set screws on
bearing shafts. Apply medium strength Locktite
#242 or equivalent to set screws before tightening.
