Section 3: Adjustments
Drive System
Your Primary Seeder uses standard no. 40 roller chain
throughout its drive system. The drive system is simple
and designed for low maintenance.
1.
Check the drive idler to ensure that it is taking up any
excess chain slack.
2.
Check each chain to ensure that it is not over-tight.
3.
Annually clean and lubricate chain with chain oil.
Packing Rollers
Refer to Figure 2-2 on page 15:
The front and rear packing rollers should turn freely. In
field position, the rear roller assembly should be free to
float up and down to follow the terrain of your field.
Seed Broadcasting System
Refer to Figure 3-1:
The seed broadcasting system gives you an even
distribution of seeds. At the rear of your seeder, beneath
the feed cups, is the seed broadcasting handle. For most
seeds, this handle should be set to the STANDARAD
BROADACASTING position shown.
Do not use the standard setting for broadcasting large,
fluffy seeds. Doing this will have a tendency to bridge and
cause the seeds to plug. Therefore; it is necessary to
adjust the seed broadcasting handle to LARGE SEEDS
BROADCAST position. This gives the seeds a larger
area to fall through to help eliminate plugging.

Seed Rate Speed Change
Refer to Figure 3-2:
The seed rate speed change is designed to give you two
speeds for different types of seeds and rates. The two
drive types are high range (fast speed) and low range
(slow speed). To change drive type:
1.
Remove chain guard.
2.
Loosen idler arm and remove roller chains.
3.
Remove nut in the center of sprocket hub, turn
sprocket hub over and reassemble. Tighten nut to the
correct torque.
4.
Reinstall drive chains and adjust drive idler to snug
up the chains. Tighten idler arm nut.
5.
Replace chain guard.
