How does a Horn Seeder disperse granules?

• A. The device uses a rotating crank to fling granules outward.
• B. The operator moves the wand in a horizontal figure-eight to disperse granules.
• C. Granules are released when the tank is pressurized.
• D. The system relies on gravity to release granules.

Answer: (B)

Granular distribution with a horn seeder relies on the operator’s sweeping motion to release and spread the product. As you move the wand in a horizontal figure-eight, granules are continuously discharged from the horn tip and projected outward in multiple directions. This pattern helps achieve even coverage over the treatment area because the release rate is controlled by how fast and wide you sweep, not by a crank, pressurized air, or gravity alone. Why this fits best: it’s a manual, non-pressurized system where the operator’s movement governs release and distance. A crank-driven mechanism would imply a mechanical fling separate from your sweeping motion, which isn’t how a horn seeder typically operates. Relying on a pressurized tank would mean the flow is driven by pressure, not by wand movement, and gravity would not provide the controlled, wide-area distribution needed.
