Abstract
A large coulter is laterally rigidly connected to a tractor. The coulter prevents lateral shifts and jerks of the tractor, thereby eliminating the tractor as a source of lateral shifts of drafted earthworking equipment. When also laterally rigidly connected to the drafted implement, the coulter practically eliminates lateral shifts of the implement as well. On a first pass, such as when plowing furrows to form beds for row crops, the coulter cuts a slot in the ground. During subsequent passes, driving the tractor over the same pairs of furrows, the coulter tracks this slot, causing the drafted earthworking implement to follow a path matching that of the implements used on the first pass. A draft member and the coulter frame also connect the drafting force exerted by the implement at a point on the tractor forward of the tractor rear axles, thus enhancing draft capabilities and fuel efficiency of the tractor while retaining the conventional rear hitch, and stabilizing the tractor as described above.
