Relief-Grinding the Reel
The new reel has a land width of 1.3 to 1.5 mm (0.050
to 0.060 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
(
).

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.
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
fairways, as any burrs will be removed, which
may create improper reel to bedknife clearance
and thus accelerate wear.
3.
Using diameter measuring tape, measure the
outside diameter of the reel at both ends (
); the difference in outside diameter between
the ends should be less than 0.010 inches
(0.250 mm). If the difference is greater, grind to
correct the difference.
Note:
Outside diameter measuring tape is
available from your authorized Toro distributor.

outermost internal supports at both ends and compare.
