Relief-Grinding the Reel
The new reel has a land width of .8 to 1.2 mm (0.03 to
0.05 inches) and a 30° relief grind.
When the land width gets larger than 3 mm (0.120
inch) wide, do the following:
1. Apply a 30° relief grind on all reel blades until
the land width is .76 mm (0.030 inch) wide
(

1. 30° 2. .76 mm (0.030 inch)
2. Spin grind the reel to achieve <0.025 mm (0.001
inch) reel run-out.
Note:
This causes the land width to grow
slightly.
3. Adjust the cutting unit; refer to your cutting unit
Operator’s Manual .
Note:
To extend the longevity of the sharpness of the
edge of the reel and the bedknife—after grinding the
reel and/or the bedknife—check the reel to bedknife
contact again after cutting at the end of each day, as
any burrs will be removed, which may create improper
reel to bedknife clearance and thus accelerate wear.
