- During normal operation, the manifolds are set so seed or fertilizer are equally distributed to all the ports. The "clean air" (air without product) lines are also open, but pressure is the same at both the elbow and manifold, thus air is not moving through these lines.
- When the drill travels into a seeded area, the Apollo seeder controller will shut product flow off to the secondary manifold(s) in the seeded area. At the same time, the metering auger speed is adjusted to maintain the desired rate across the remaining open secondary manifolds.
- The "clean air" (air without product) line(s) remain open, but air flow is now diverted from the primary elbow to the line without product. The diverted air flow maintains the balance of distribution to the remaining open lines, and also purges product from the line where the product has been stopped.
- Dual ASC provides the ability to set overlap separately for seed and fertilizer. Farmers can set the geometry and on/off timings individually, allowing even finer settings resulting in less overlap and increased savings. This feature also applies to NH3 or liquid fertilizer application.
The Dual Auto Section Control option is available on all 7000 Series air seeders with Apollo seeder controller systems.
Auto Section Control Justification
Bourgault conducted an agronomic study to develop a real-world example of the fiscal benefits of the ASC option. Find out more how the ASC option can help you.
Hydraulic Knife Valve Control
Knife valves are controlled by the Apollo seeder controller system and hydraulically actuated, with the supply coming from the fan #1 hydraulic circuit.
Number of Sections
Dual ASC is capable of controlling 6, 8, or 10 drill sections, depending on drill size on spacing.
Each knife valve is equipped with a proximity sensor, providing feedback to the Apollo seeder controller thus reassuring the operator that it is performing as expected.
