Abstract

The invention relates to a harrow for tractor which has a simple and safe structure with efficient levelling work through free adjustment of the inclination angle of a harrow plate relative to the ground with safety. The harrow for tractor comprise a plurality of connecting rods (10) hinge-connected to the rotavator (2), a harrow plate(20) hinge-connected to the hinge axises (23a) of the rear ends of the connecting rods (10), a connecting arm(22) formed projectingly upward on the harrow plate(20) and a lifting cylinder (50) mounted on the bracket(4) extending upward from the rotavator (2) and hinge-connected to the hinge axis (22a) of the top end of the connecting arm (22), wherein the hinge axis (22a) for connecting the harrow plate (20) and the lifting cylinder (50) is arranged so as to be positioned above the hinge axises (23a) for connecting the harrow plate (20) and the connecting rods (10).
