Patent ID: 8567518

Claim:
A device comprising a frame having a main beam extending in a longitudinal direction, wherein the main beam defines a longitudinal axis, and two side arms extending on both sides of the main beam to support one or more agricultural tools, wherein the side arms are hingeably connected at an inner end of the side arms to a slide connection which is slidable along the main beam, wherein the side arms are displaceable between a transport position, in which they substantially extend along the main beam, under a first angle with the main beam, and a working position, in which the side arms extend from the main beam, under a second angle, larger than the first angle, wherein the side arms are displaceable between the transport position and the working position by sliding of the slide connection along the main beam at the location of the side arms, wherein the side arms and the main beam are interconnected at a distance from the slide connection by a respective holding rod that is hingeably connected at both ends to the respective side arm and the main beam, wherein the inner ends of the holding rods are stationary attached to the main beam when viewed in longitudinal direction, wherein the main beam is provided at the front end with a coupling to a tractor, wherein the inner ends of the holding rods and the coupling are mutually stationary when viewed in longitudinal direction, wherein each side arm is provided with a support wheel for supporting the side arm in the working position and in the transport position, and wherein the coupling and the two support wheels form the sole support points for the device in the transport position, and wherein each of the side arms carries one or more tools.
