Low disc speeds and long spreading vanes then permit gentle and even acceleration of the fertiliser to the optimum ejection speed. This results in precisely defined trajectories and thus in optimum spread patterns.
Speed-related spread rate control on the fertiliser spreader is recommended particularly when used behind tractors with power shift gear boxes to make use of the full capacity. These elements are operated either via the AMADOS on-board computer or – if the “Tronic” package is used – via the AMATRON.
Longitudinal distribution can be further optimised by means of weighing systems. On the ZA-M Profis and ZA-M Ultra Profis spreaders Amazone have integrated a weighing cell and tilt sensor in a parallelogram mounting frame.
