Abstract: A quick-attachment system may be used for attaching an agricultural planter to a strip till. A frame is initially installed on a strip till and may remain permanently attached to the strip till so that the strip till may be separately used in normal operation with the frame attached but without a planter attached. For combination tilling and planting operations, a planter may be attached by completing a three-point hitch attachment to the frame so that a tractor may be used to pull the combination of strip till and planter. Hydraulic cylinders connected to the frame and to the planter may be used to lift and lower the planter relative to the strip till.

Abstract: Stabilizng arms are applied to an agricultural tractor having a three point hitch with a quick hitch frame. Specifically, a belly plate is added to the frame beams about half way between the front axle and the rear axle. A horizontal frame draw bar extends from the belly plate to a pivot pin mounted by a clamp below the rear axle housing. The stabilizing arms extend from the pivot pin below the axle housing back to a quick hitch frame pin, which is an extension of the quick hitch pin and extends outboard of the quick hitch frame on each side thereof. A cross brace extends between the stabilizing arms to form a rigid stabilizing frame. Because the pivot pin below the axle is not coaxial with the pin by which the normal draft links are connected to the differential housing of the tractor, it is necessary that the stabilizing arms be pivoted so that the quick hitch frame can be mounted to have its normal motion to raise and lower the tillage implements connected to the quick hitch frame.

Abstract: An implement-mounting linkage mechanism for pivotally connecting a frame to a wheeled implement is disclosed. The mechanism is preferably used for pivotally connecting a wheeled load-bearing frame to the backside of a wheeled farm implement. The frame includes wheels adjustable relative to the frame for raising and lowering the frame relative to the ground.

Extension power lines for powering the steering mechanism and the hitch control mechanism are coupled between the tractor power lines and the remounted front wheel assembly. The extension frame is also articulated at its connection point to the frame of the tractor for improved control of the tractor assembly. A mechanism is provided for shifting the farm implement laterally with respect to the front wheels of the tractor for proper alignment of the implement with the crop rows. Spring shock absorbers are also provided for cushioning forces to the agricultural implement caused by uneven terrain.

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.
