With AXMAT, Rauch presents the world's first solution featuring automatic online measuring of fertilizer distribution and automatic adjustment of a disc fertilizer spreader to the fertilizer type in the tank and the desired working width. For the first time high fertilizer distribution precision is achieved automatically with the aid of microwave sensors and an automatic adjustment system on the fertilizer spreader. An arm swivelling about the distributor disc of a disc fertilizer spreader provided with microwaves records the spread fan position beneath the fertilizer spread fan, without contact, and sets the spread pattern automatically to the desired working width with the aid of the rotatable tank bottom and dosing aperture.
During the spreading process, the spreading pattern is monitored permanently and the discharge point of the fertilizer to the distributor disc is readjusted automatically as required. The novel, automatic self-setting of the fertilizer spreader to the required working width makes it possible to achieve higher precision than is otherwise encountered in conventional adjustment practice and achieves this without the need for any spreading test on the field. The permanent self-monitoring of the spread fan also allows automatic online readjustment of the setting system to the set working width in response to changing fertilizer batches or changes in weather conditions.
It improves fertilizer efficiency, reduces emissions and fertilizer costs, and increases the yield security. Initial test results of the French test institute IRESTEA confirm the said advantages of the system.
