Abstract of the Disclosure The present invention provides a harrow hinge, and an improved self-levelling harrow incorporating the hinge for dragging from a harrow bar. The harrow comprises a frame, a plurality of tines and tine supporting means mounted on the frame, and the hinge for mounting the harrow on the harrow bar. The hinge comprises a harrow bar mount for rigid connection to the harrow bar, a harrow mount for rigid connection to the harrow, and upper and lower rigid connections between the harrow bar mount and the harrow mount, each of said rigid connections being pivotally connected to the harrow bar mount and harrow mount. The upper rigid connection may be of adjustable length. When in operation, the improved harrow self-adjusts and sustains a more evenly distributed tine contact over uneven ground, compared with prior art harrows.
