Grinding Relief Angles on Reels
Grinding the Angles
Relief grinding should be “tailored” to suit the applica-
tion of the reel mower. The angle of the grind should
be sufficient to last for a full season of use before nor-
mal wear completely removes all the relief. For exam-
ple, a mower being used on Kentucky bluegrass fair-
ways in Ohio will experience much less wear that a
mower being used on a Zoysia grass sod field in Ari-
zona
NOTE
These specification are to be used as a guide
only if the original equipment manufacturer's
specifications are not available. The manufac-
turer's recommendations should be followed
when grinding reels.
A 10 degree relief angle is considered minimum; a 25
degree relief angle average and a 45 degree relief
angle the maximum that should be ground on reel
blades.
The land area of reel blades should have a surface no
wider than .060 or less, which is equal to approxi-
mately 1/3 of the blade thickness.
