REEL-TO-BEDKNIFE (Pre-Adjustment
Check)
1.
Check the reel for end play or radial play.
If there is any abnormal movement of the
reel, up and down or side to side, adjust or
replace components as needed.
2.
Inspect the blades and bedknife.
a. The blades should not have bends or
nicks. The leading edge of the blades
must be sharp, free of burrs.
b. The bedknife and bedknife backing
must be securely fastened. The bedknife
must be straight and sharp.
c.
A flat surface of approximately 4 mm
should be maintained across the face of
the bedknife.
3.
If wear or damage is beyond the point
where the reel or bedknife can be corrected
by the lapping process, they must be re-
ground or replaced.
4.
Proper reel to bedknife adjustment is
critical. A gap of 0,025 to 0,05 mm must be
maintained across the entire length of the
reel and bedknife.
a. A reel that is not parallel to the
bedknife will wear conical in shape.
b. A reel set too tight will lose its sharp
edges prematurely and may result in
wavy wear pattern in the bedknife.
5.
Grass conditions will also affect the
adjustment.
a. Dry, sparse conditions will require a
wider gap to prevent heat buildup and
damage to the reel and bedknife.
b. When cutting for high quality grass
with a good moisture content, a closer
clearance (near zero) provides a better
cut and also increases the life of the reel
and bedknife.
