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.

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.

Seed Broadcasting Handle Adjustments

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.
