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 insure that it is taking up any
excess chain slack.
2. Check each chain to insure that it is not over-tight.
3. Annually clean and lubricate chain with chain oil.
Roller Packing Wheels
The front and rear roller packing wheels 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.
See Figure 2-2.
Seed Broadcasting System
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 standard setting,
see Figure 3-2.
Using the standard setting for seed broadcasting large,
fluffy seeds will have a tendency to bridge. This results in
plugging. Therefore; it is necessary to adjust the seed
broadcasting handle to the LARGE SEEDS
BROADCAST position, Figure 3-2. This gives the seeds
a larger area to fall through to help eliminate plugging.

NOTE: The agitator option can be used when
seeding large, fluffy seeds to prevent bridging in the
seed box. However, bridging may still occur in the
feed cups if there are stems or leaves mixed in with
the seeds.
Seed Rate Speed Change
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).
15 Bushel Speed Change
To change the drive type, loosen the drive idler arm nut.
Remove the nut in the center of the hub, and turn
sprocket hub over. The chains should remain on the
same sprockets. Reassemble sprocket hub and install
drive chains. Adjust the drive idler to snug up the chains,
Figure 3-3 on page 19. Replace chain guard.
30 Bushel Speed Change
To change the drive type, loosen the idler arm nut.
Remove the chains and the nut in the center of sprocket
hub. Turn sprocket hub over and reassemble. Install
drive chains then adjust the drive idler to snug up the
chains. Figure 3-3 on page 19. Replace chain guard.
