Abstract

278,904. Sack, R,. [Firm of], and Ehricke, M. Nov. 13, 1926. Couplings for tractors and agricultural implements comprise a vertically movable member, for carrying and dragging the implement, a vertically movable arm connecting this member to the tractor, and a support for the member, which rests on the ground when the implement is lowered. As applied to a turn-wrest, plough, the usual horizontally rotatable bracket 19, carried by the tractor is connected by a horizontal pivot 18 with an arm 4 the rear end of which is connected by a horizontal pivot 6, with a, member 7 housing a longitudinal shank secured to the plough. The shank is rotatable in the member 7 for allowing the plough to be reversed. The member 7 is connected by a slotted link 1 to the arm 4. To the pivot 6 is fixed a pair of arms 9 carrying an axle 12 provided with a. pair of ground wheels 11. The angle which the arms 9 make with the member 7 is adjusted by a handle 8 provided with a locking catch, regulating the depth of the furrow. For transport., the plough is raised, in known manner, by chain 14 and a lever 15 operated by and carried on the tractor, the wheels 11 being also raised clear of the ground. The axle 12 has play in its supports, so that it may. assume positions inclined to the horizontal. It is restrained from much horizontal deflection by springs 24, Fig. 4, or abutments 26, Fig. 5.
