3. The goal is to set the front coulter
discs to cut ¼” deeper than the seed
depth. With the machine on the
ground and the tires touching the
ground, whatever distance the tires
are adjusted up from the ground is
roughly the depth the coulter discs
will cut ahead of the seeder discs.
Hydraulic Cylinder setup:
Use cylinder
stops to set the maximum height that the
tires can be lifted while achieving proper
seed depth.
Turnbuckle Setup:
rotate top links to lift
tires off the ground approximately the
distance desired to achieve proper seed
depth.
4. Test the gauge setting by operating
the Multi-drill where seeding is
desired. Observe the gauge wheels
during the test; if they don’t touch the
ground, weights can be added to the
Multi-Drill frame.
5. Measure the results of the test. For
drastic changes, the gauge wheels can
be further adjusted, but for small
depth adjustments, the turnbuckle on
each seed disc assembly can be
rotated to lift or lower the seed within
the trench made.
6. Repeat these last steps until desired
seed depth is achieved and don’t
forget to occasionally verify seed
depth during operation. Soil
conditions can change over the course
of operation.
Changing Seed Plates
The seed plates are strategically positioned
between the hopper’s outlet holes (seen when
the hopper is empty) and the “cutoff plate”
which the linear actuator shuttles back and
forth to start and stop seed flow.
Each set of plates are labeled with laser
etching on one side: “left”, “right”, and their
respective sizes.
In order to change the seed plates, the hopper
must be clean. If the plates are removed with
seed in the hopper, the seed can wedge
between the “cutoff plate” and the hopper
outlets making it impossible to slide the next
set of plates into place.
The seed plates are changed using the
following steps:
1. To change plates you will need two
9/16” wrenchs and the Adjuster
Wrench, DS27-026. Using the small
end of the Adjuster Wrench, located
on top of chain cover as shown in
Figure 9. Loosen and remove the two
½” carriage head bolts connecting the
adjuster handle to the Adjuster mount
as shown Figure 11.
2. Pull straight out on the adjuster
handle and slide the seed plate
assembly out of the seed box as
shown in Figure 12.
3. Using the 9/16” wrenches, loosen and
remove the 3/8” bolts connecting both
