Seed Metering Rotors
The a-drills are delivered with two types of rotor: one for small seeds (rape, mustard, cabbage, clover, etc …), and a medium rotor for seeds (vetch, grass, sunflower, …). The agitator placed above the rotor ensures a steady stream of seeds. A brush, located at the base of the rotor, will regulate the flow and improve the setting accuracy.
For large seeds (peas, horse beans, etc …), it is strongly advised to choose the Flex rotor option, which is able of deforming with large seed diameter.
