Abstract: An agricultural implement arrangement is disclosed that may provide wheel assemblies that are stored in front of wing assemblies and row units mounted thereon. The arrangement may include actuators to extend the wheel assemblies in order to lift the row units off the ground to move to a transport position. When in a fully-folded position, the wing wheel assemblies may interleave. The arrangement may also shift the weight of the wing assemblies while in transport position to the hitch of the tractor and center the rearward weight over the central wheel assembly.

Abstract: A novel and practical track-filling apparatus for smoothing rutted soil formed by the repeated passage of wheels. This apparatus includes a frame, a system for attaching the frame to a tractor, and a soil moving blade assembly mounted to the frame. This blade assembly has laterally disposed and spaced apart left and right blades. A system for adjusting the included blade angle between these blades is also provided. This system for adjusting includes a single blade adjusting hydraulic ram that is operatively connected to the blades via a novel yet simple and reliable linkage assembly. Additionally, systems for lifting and tilting the apparatus optimizes operation of this track-filling apparatus over irregular and differing terrain.

Abstract: The invention relates to a quick hitch guidance system which allows an operator to maintain proper alignment with a farm implement while towing it behind a tractor. The device includes an exterior inverted U-shaped frame with an external quick hitch coupling element. Within the frame there is attached a double rod hydraulic cylinder which operatively moves internal linkage within the frame so that the distance between the device and the tractor is increased on one side and decreased on the other thereby steering the implement into proper alignment. The implement moves independent of the tractor so that as the tractor deviates laterally from alignment with the crop rows, the position of the implement is corrected and aligned with the rows to prevent crop damage.

Abstract: An attachment accessory for an angularly adjustable agricultural implement guidance system that allows guidance of a pull-type implement thereby. A plurality of rotatable coulters which engage the ground are attached to a rigid frame which is connected to the guidance mechanism and tows a pull-type implement.

Abstract: A guidance system for an agricultural implement pulled by a tractor is disclosed. The implement, such as a cultivator or planter, has ground-engaging discs mounted to a frame or toolbar and includes a control hitch mounted to the conventional three-point tractor hitch. The toolbar of the implement is mounted to the control hitch for rotation about a vertical axis. A first sensing device senses the position of the implement relative to a desired lateral position, such as the distance from a crop row, and generates a signal representative of the displacement of the implement from that desired lateral position. The sensing device actuates a hydraulic circuit to turn the implement toolbar toward the desired position; and the discs steer the implement toward the desired lateral position. A second sensing device senses the angular position of the implement relative to the control hitch.

Abstract: A method of guiding farm equipment is provided. The method includes the steps of attaching a trench forming device to a tractor in front of the rear wheels of the tractor, traversing ground with the tractor equipped with the trench forming device set to a desired depth, forming a trench for guiding farm equipment in front of the rear wheels of the tractor as the tractor traverses the ground, engaging guide wheels attached to the farm equipment in the trench, and guiding the farm equipment by tracking a path provided by the trench. A trench forming device is also provided. The trench forming device includes a trench forming mechanism for forming a trench in ground traversed by a tractor equipped with the trench forming device.

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: 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.

Abstract: A row crop planter supports at least two vertical guide making blocks to form superficial trenches about four or five inches deep precisely midway between adjacent rows as they are planted. Tires with trench-riding central ridges on front wheels of a tractor powering a subsequent row crop processing implement along these rows serve to guide the tractor down the rows. Vertical guide following blocks on such a subsequent processing implement such as a cultivator, for example, find and follow exactly the previously formed trenches and so serve to guide cultivator blades to follow every minor deviation of the rows, even on hillsides causing the implement to be tilted transversely of the direction of movement of the implement down the rows. The depth of the guide trenches and the depth of penetration of the guide following blocks is determined by implement support wheels near those blocks.

Abstract: A plow/harrow combination comprising a harrow member extending sidewardly from a plow blade, the harrow teeth having an elongated cross section with the cross-sectional length axis inclined in relationship to the direction of travel, thus creating a compensating force on the plow blade, the combination also including a release and reset mechanism, which, when the harrow member is obstructed by an object creating a load exceeding a predetermined level, causes the release of the harrow member from the original position and a pivoting movement of same in a substantially horizontal plane, the harrow member being automatically returned to the original position as soon as the load on the harrow member no longer exceeds the predetermined load.
