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.
