Front Coulter Disc Shaft
The Multi-Drill is equipped with a coulter
disc shaft mounted to the front of the frame.
The function of this shaft is to cut a narrow
slit in the ground in preparation for the seed
delivery to follow. The cutting depth of the
shaft is manipulated using the gauge wheels
on the sides of the frame. The ND-60 gauge
wheels are set by lifting the machine and
selecting one of the numbered holes to pin
located on each side of the machine beneath
the hydraulic cylinders. Whatever the
desired depth of the final seed delivery may
be, it is recommended that these coulter discs
be set to cut ¼” deeper to allow adequate
room for the seed to easily fall in and be
packed into place.
Seed Disc Assembly
Often referred to as double disc openers, the
Multi-Disc sports offset discs which follow
directly behind each coulter disc and are
specifically designed to open the slit made by
the preceded coulter and drop seed from the
primary hopper in the trench made. Each
seed disc assembly is comprised of two
angled discs, pressure spring, turnbuckle,
seed tube, and press wheel. The seed depth
is adjusted utilizing the turnbuckle.
Shortening the turnbuckle shallows the seed
while lengthening the turnbuckle pushes the
seed deeper into the slit cut by the coulter
disc. The seed tube receives the hose from
the primary box and drops the seed directly
between the discs at the measured depth
created by the discs. The press wheel utilizes
the force from the spring to firm up the soil
over the seed.
Seeders
The Multi-Disc is equipped with a standard
hopper, referred to as “primary”, while
having the capability of adding a smaller
hopper for simultaneous applications. The
seeders are comprised of a hopper, seed
plates, electric actuator, motor, and one
handheld control harness. Each seeder
utilizes the same metering principle and
delivery system. The outlets on the bottom
of the seeders have their sizes adjusted
