Relief-Grinding the Reel
The new reel has a land width of 1.3 to 1.5 mm (0.030
to 0.050 inch) 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 1.3 mm (0.050 inch) wide
(Figure 23.
1. 30°
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 2 greens, as any burrs
will be removed. Burrs may create improper reel to
bedknife clearance, which can accelerate wear.
