Quantity effect-free metering aperture


If it is intended to spread a constant application rate it is necessary to match the size of the metering aperture to the prevailing operational speed. Thanks to the shutter slide, this task is fulfilled very quickly and sensitively. Due to the kidney-shaped design of the metering aperture, the spread pattern remains unchanged and precise, even at varying operational speeds so that the position of the delivery system does not require any adjustment. Stage 1: Hopper aperture slightly open Stage 2: Hopper aperture half open Stage 3: Hopper aperture wide open
