Reliable spreading technology tailored to field requirements

  • The binding agent spreaders in the MA model series are mounted on two-axle or three-axle carrier vehicles and are ideally suited as mobile spreading units for all kinds of off-road and on-road applications.
  • The binder is metered and spread by means of a large, hydraulically driven spreading auger.
  • Continuously variable adjustment of the spread rate and the metering unit integrated into the spreading auger ensure uniform and precise binder discharge.
  • A pneumatic filling device on both sides, left and right, ensures quick and efficient filling of the binder container.
