ABSTRACT OF THE DISCLOSURE The invention relates to a new hitch or drawbar assembly for use with agricultural implements towed in a train of implements behind a tractor or the like. The assembly includes a drawbar that is shorter than normal and is pivotally connected to a primary unit, such as a cultivator, for adjustable pivoting action about a horiz- ontal axis, The drawbar is connectable to a towing or intermediate unit on or closely adjacent to the axis of the ground-engaging wheels of the intermediate unit. That connection point is also on or closely adjacent to a reaction line drawn between the connection point of the intermediate unit and the ground-engaging area of imple- ments carried by the primary unit. As a consequence, the turning radius of the train is decreased; the primary unit is better able to follow undulating terrain, thereby main- taining a more consistent working depth for its implements; and vertical loads transferred back from the primary unit to the intermediate unit are lessened, thereby reducing wear on its wheels and associated running gear.
