Abstract

The folding harrow has a three-point coupling for attachment to the tractor. The support (3) for the folding-frame (4) comprises a transverse beam (6). Two lengthwise and sideways triangles (8) are situated at the back and on each side of the three-point coupling, the back part of which has a transverse hinge (9). The tipping device consists of two hydraulic jacks (11) with cylinders hinged on transverse pivot (12). The piston for each jack is hinged to a transverse pivot (3) on the front end of the chassis. The harrow support frame has a central part and two side-parts hinged on lengthwise axes on the central part. Each of the three parts consists of two transverse beams (19) rigidly joined by two lengthwise beams (20).
