Abstract
A movable implement for loosening soil below ground, in which a row of blades with blade holders are located perpendicular to a direction of motion of the implement. A supporting arm has one end articulated to each blade, and a frame is articulated to another end of the supporting arm. The supporting arm is engaged by a connecting rod of a crank device, which operates in a vertical plane parallel to the direction of motion. The supporting arm mounts a blade adjustment lever with two arms. The adjustment lever pivots coaxially with an articulating shaft. A stop is mounted on a downward-extending arm of the blade-adjustment lever, and points below the articulating shaft. A lever-adjusting device has a variable angle to the supporting arm for varying the angle of the blade to the ground. A spring forces a blade holder against the stop. The blades are forced away from the stop during movement of the implement.
