BEDKNIFE-TO-REEL

(Pre-adjustment Check)
1. Check the reel bearings for end play or
radial play. There should be no end play
or radial play. See Section 3.7.
2. Inspect the reel blades and bedknife to
insure good sharp edges without bends
or nicks.
a. The leading edge of the reel blades
(F) must be sharp, free of burrs and
show no signs of rounding off.
b. The bedknife and bedknife backing
must be securely tightened. The bedknife
must be straight and sharp.
c. A flat surface of at least 1.5 mm
minimum must be maintained on the
front face of the bed-knife.
Use a standard flat file to dress 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 reground.
4. Proper reel-to-bedknife adjustment is
critical. A gap of 0.025 to 0.076 mm
must be maintained across the entire
length of the reel and bedknife.

BEDKNIFE ADJUSTMENT

1. Read Section 3.4 before making the
adjustment.
2. Start adjustment at the leading end of the
reel, followed by the trailing end. The
leading end of the reel blades is that end
which passes over the bedknife first
during normal reel rotation.
CAUTION
To prevent personal injury and damage to
the cutting edges, handle the reel with
extreme care.
Use adjusters (G and H), to adjust gap.
3.
Loosen bottom adjuster (H) and turn top
adjuster (G) down (Clockwise) to close
gap.
a. Slide a feeler gauge or shim stock
0.025 - 0.075 mm between the reel blade
and

MAINTENANCE AND PARTS MANUAL
5. The reel must be parallel to the bedknife.
An improperly adjusted reel will lose its
sharp edges prematurely and may result in
serious damage to the reel and bedknife.
6. 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. High quality grass with a good moisture
content requires a closer gap (near zero).
b. Adjust the trailing end of the reel to the
same gap in a similar manner then
recheck the adjustment at the leading
end.
c. When the reel is properly adjusted to
the bedknife, the reel will spin freely and
you should be able to cut a piece of
newspaper, along the full length of the
reel, when the paper is held at 90° to the
bedknife.
Note: Avoid excessive tightening or serious
damage may result to bedknife and reel blades.
Reels must turn freely.
