ADJUSTMENTS
Lithium
•
A flat surface of at least 1/32 in. (0.08 cm) minimum
must be maintained on the front face of the bedknife.
Use a standard flat file to dress the bedknife.
•
If wear or damage is beyond the point where the reel or
bedknife can be corrected by the lapping process, they
must be reground.
•
Proper reel-to-bedknife adjustment is critical. A gap of
0.001 to 0.003” (0.0025 to 0.0076 cm) must be main
-
tained across the entire length of the reel and bedknife.
•
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.
•
Grass conditions will also affect the adjustment.
•
Dry, sparse conditions will require a wider gap to prevent heat buildup and damage to the reel and bedknife.
•
High quality grass with a good moisture content requires a closer gap (near zero).
BEDKNIFE ADJUSTMENT _____________________________________________
•
on page 77 before making the
adjustment.
•
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.
•
Use adjusters
(B
and
C)
, to adjust gap. Rotate adjusters
(Clockwise) to close gap. Each click of the adjuster moves
the bedknife 0.001” (0.0025 cm) closer to the reel.
•
Slide a feeler gauge or shim stock 0.001” - 0.003”
(0.0025 - 0.0075 cm) between the reel blade and the
bedknife. Do not turn the reel.
•
Adjust the trailing end of the reel to the same gap in a
similar manner then recheck the adjustment at the
leading end.
•
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.
NOTICE
Avoid excessive tightening or serious damage may
result to bedknife and reel blades. Reels must turn
freely.
