Coulter Adjustments (LC25/40)
Coulter or Tire Height
Refer to Figure 22 (a cutaway view of the coulter row)
Coulter or tire height
is the adjustment for tool depth
(lister shovel or cultivator).
A crank
, found on a stob at the rear center of the tool
bar, is provided to make the adjustment.
A scale bar
provides reference graduations. The front
edge of the bar has major graduation reference marks
“1” to “5”, with an edge notch every
1
2
graduation. The
rear edge of the bar has notches at the
1
4
graduations,
but no reference marks. The reference point for the scale
is the top face of the pivot plate
.
Each
1
2
number graduation represents approximately
1 inch (2.5 cm) of vertical coulter movement. “1” is
deepest. “5” is shallowest.
Never adjust the coulter beyond mark “5”. The
adjuster separates at settings shallower than “5”.
The coulter/tire arm adjustment plates
have two pivot
holes, providing an additional range of adjustment.
To adjust coulter/tire height:
1.
Raise the implement. Coulter/tire adjustment can be
made with the implement lowered, but requires more
effort. Release the crank from storage.
2.
At a row, note the current setting on the scale
.
Each
1
2
number graduation represents
approximately 1 inch (2.5 cm) of vertical coulter
movement.
3.
Remove the wire-retained pin
.
4.
Place the crank on the threaded rod
. Rotate the
crank until the desired scale value appears at the top
face of the pivot plate
. Adjust crank to align the pin
hole in the thread rod with the slot in the scale.
5.
Re-install the wire-retained pin.
6.
Re-check tool depth, arm parallelism and hitch
height, then repeat step 3 through step 5 for all rows.
The threaded rod may only be pinned at half turns
(180
). Each half turn is
1
12
of a major graduation (
full turns per major graduation).
Equipment Damage Risk:
Do not use scale values below “1” or above “5”, or pin
and/or scale damage may result.
