Bedknife Adjustment - Jacobsen Eclipse 118 63313 Technical Manual

BEDKNIFE ADJUSTMENT ___________________________________________________

1. Read Section 8.2 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.
3. Additional access to bedknife adjusting hardware (B
and C) can be obtained by pressing the limit bracket
(A) away from the reel as the mower is tipped back
onto it's handle. This allows the back side of the reel
to pivot down and away from the frame.
NOTICE
Gen-Set Power Modules: Do not leave the mower
tipped back for an extended length of time or oil may
migrate into the combustion chamber.
4. Use adjusters (B and C), to adjust gap. Loosen
bottom adjuster (C) and turn top adjuster (B) down
(Clockwise) to close gap.
a. Slide a feeler gauge or shim stock 0.001" -
0.003" (0.025 - 0.075 mm) between the reel
blade and the bedknife. Do not turn the reel.
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.
NOTICE
Avoid excessive tightening or serious damage may
result to bedknife and reel blades. Reels must turn
freely.
4. Return mower to upright position. Limit bracket (A)
is spring loaded and should latch into bracket on
reel.
