ABSTRACT:
The back part of the underframe is fastened to the center point of the three-point lift of the tractor by an eye-bolt the shaft of which is rotatable mounted on said part.
The side part of the underframe is comprised of a part which bears a wheel on the ground and carries a bearing for the arm of the tilling machine, an extension piece and a connection piece, lockable in several positions to the extension piece and hingably fastened by a pin and a fastening piece to the tractor adjacent the engine.
The complete underframe can tilt relative to the tractor about the hinging axes formed by the eye-bolt and the pin, extending in the lengthwise direction of the tractor.
Even with a height differential between the wheel and the tractor no large turning moment can be generated in the underframe or its fastening.
