For a REVERSE HELIX reel, the grinding wheel should
be dressed to match the angle of the reel blade. It is
recommended that a slightly larger angle is dressed on
the wheel so the right side of the wheel is contacting the
blade prior to the left side as shown. The grinding wheel
will then wear to a match.
If you do not dress the grinding wheel so the right side
contacts first you may not relief grind part of the last 3/8"
[10 mm] of the blade.
REVERSE HELIX
NOTE: A wheel that has been worn to match a normal helix
can generally be removed and reversed to grinder reverse
helix. reels.
Reverse helix reels are also refered to as Right Side
Cutting First reels (Looking from the front - grass entry
side) or Left Throw reels (Throws grass to the left of the
operator position.)
