REVOMAT overload safety device


If the chisel opener hits an obstacle, e.g. heavy stones or compacted headlands, the upper link abruptly gives way at an exactly pre-set pressure. The coulter jumps upwards and immediately returns into the work position. Automatically, super! With obstacles that are just hit on the angle in the direction of travel, the coulter just moves to the side – because the entire lower link is not rigid but a one-piece long spring plate. Also again automatic, super. (1) Top link straight chisel opener in operational position (2) Top link cranked chisel opener “deflected” after hitting an obstacle in the soil
