PURPOSE: A plow for a tractor is provided to enable the adjustment of a connection angle between the plow and the tractor, and to freely control the width of furrows by easily changing the distance between plowshares. CONSTITUTION: The plow for a tractor comprises a frame integrated to the tip end of a connection bar for the tractor, a transverse bar(105) fastened to the tip end of a connecting member of the frame by a bolt, and a plow-share(107) located on a lower end of a plow-share strut(106) coupled to the transverse bar. A bracket(110) is rotatively coupled to an upper end of the plow-share strut with a connecting pin(109), and the bracket is coupled to the transverse bar with a desired fastening device. An adjustment screw(112) is screwed to an inclined surface(111) of the bracket so that the adjustment screw is advanced or withdrawn according to the rotating direction of the bracket. A fastening pin(113) of the plow-share support is moved along a groove(114) formed in the bracket in order to fix the position of the plow-share support tilting according to the movement of the adjustment screw.
