ABSTRACT:
A method for loosening stony soil by means of a rotating cutting head fastened to the rear of a tractor and having cutting members to be drawn through the soil and being mounted according to a helical line.
Stony soil can be readily loosened to the desired depth because the cutting head can be kept at an acute angle to the direction of movement. So the cutting head is drawn in a stable manner in the direction to the tractor against the stone surface concerned and penetrates the stony soil like a plough, the soil above the cutting head being torn up upwardly.
