Coulter Blades
1. The 2112 Coulter Chisel is equipped with 22" coulter
blades.
2. The 22" diameter blades are flat with a thickness of 4
ga (.256") and are standard for the 2131 Wing
Coulter Chisel.
3. Sharpening – In some cases there is a desire to
sharpen coulter blades for improved cutting. There
are several people who roll-sharpen coulter blades.
Most coulter blades used today are made of
chrome-boron steel. The chrome-boron steel has a
higher hardness than traditional carbon-steel blades
for increased wear. Higher hardness makes roll
sharpening more difficult often with mixed results,
and is not covered by warranty. Coulter blade
manufacturers will not cover any alterations to blades
other than the place of manufacture. Results from
roll-sharpening damage may not be immediate, and
may take more than a season to be noticeable. If you
choose to sharpen coulter blades, check with local
dealers for reputable experienced sharpeners that
will stand behind their work.
Coulter blades are extremely sharp. Exercise
extreme care when working on or near coulter
blades. Do not allow coulters to roll over or fall
onto any body part. Do not allow wrenches to slip
when working near coulter blades. Never push
wrenches toward coulter blades. Do not climb
over machine above coulter blades. Failure to
stay clear of coulter blade edges can cause
serious personal injury or death.
DANGER
OPERATION AND MAINTENANCE
Depth Stop Adjustment
The operating depth of the 2112 Coulter Chisel is
controlled by a single-point depth stop. The stop is
located at the center front of the machine.
1. Adjust the depth stop by turning the handle in
(counter-clockwise) to increase operating depth
Figure
4-5. Turn the handle out (clockwise) to
decrease operating depth. One turn will equal
approximately1/8" adjustment in depth. Arrows on
the front will also show this.
2. The gauge on the side of the depth stop tube gives a
reference for depth setting. The "A" setting refers to
maximum operating depth.
IMPORTANT
For maximum operating depth, the lift wheels must
be in contact with the ground and carry some of the
machine weight. Raising the lift wheels off the
ground permits uncontrolled depth and does not
allow the leveler to function properly.
