10.8 BEDKNIFE ADJUSTMENT __________________________________________________
1.
Read Section 10.7 before you adjust the reel.
2.
Start the adjustment at the leading end of the reel,
followed by the trailing end.
The leading end of the
reel blades is that end which moves over the bedknife
first during normal reel rotation.
3.
Use the adjusters, to adjust the gap. Rotate the
adjusters to the right side to close the gap. Each click
of the adjuster moves the bedknife 0.001 in. (0.0025
cm) closer to the reel.
a
Put a 0.001 - 0.003 in. (0.0025 - 0.0075 cm) feeler
gauge or shim 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
same method then inspect the adjustment at the
leading end.
c
When the reel is correctly adjusted to the bedknife,
the reel will rotate freely. When a piece of newspaper
is held at 90° to an adjusted bedknife, you can cut a
piece of newspaper, along the full length of the reel.
10.9 CUTTING HEIGHT _________________________________________________________
Note:
Always make the reel-to-bedknife adjustment before you adjust the height of cut.
1.
Lift the cutting units to the transport position. Set the
parking brake switch in the ON position, stop the
engine and remove the key from the ignition switch.
2.
Set the height of cut (HOC) on the HOC gauge.
a
Measure the distance between the bottom of the HOC
screw head and the gauge surface.
b
Adjust the HOC screw to get the correct height then
tighten the wing nut.
3.
Loosen the flange nuts on the front roller brackets to
allow the adjuster to lift or lower the roller.
4.
Put the HOC gauge across the bottom of the front and
rear rollers at one end of roller.
5.
Move the head of the HOC screw over the bedknife.
Rotate the adjuster knob to close the gap between the
screw head and bedknife.
Repeat Steps 4 and 5 on the opposite end of the reel.
Complete the adjustment to one end before you
adjust the opposite end.
6.
Tighten the flange nuts and recheck each end.
NOTICE
Avoid excessive tightening or serious damage may
result to bedknife and reel blades. Reels must turn
freely.
