The subsoiler with hydraulic protection with a gas accumulator and a breakaway accumulator is designed to break up and loosen compacted plough pans resulting from ploughing performed at constant depths, as well as to loosen compacted subsoil resulting from heavy mechanical equipment running across the field surface.
Subsoiling improves air and water conditions, and facilitates fertiliser penetration into deeper soil layers.
