Abstract: An agricultural vehicle includes a frame and a plurality of suspension assemblies coupled to the frame. The plurality of suspension assemblies configured to together increase or decrease a vertical distance between the frame and a surface supporting the agricultural vehicle. The agricultural vehicle also includes a plurality of wheels. One wheel of the plurality of wheels is coupled to each suspension assembly, and at least two wheels of the plurality of wheels are movable about a steering axis. The agricultural vehicle further includes at least two actuators. Each of the at least two actuators is coupled to a respective suspension assembly of the plurality of suspension assemblies and is configured to move one of the at least two wheels.

Abstract: A system for planting cover crop seeds in fields with standing row crops, including a high-clearance agricultural vehicle with a high-clearance toolbar, soil sealers, and a seeder with a reciprocator above the soil sealers to deliver various types of seeds onto the disrupted soil after which the soil sealers cover the seeds with soil.

Abstract: Methods, systems, and apparatuses for rotating a boom assembly relative to an agricultural vehicle. The system is arranged with a fixed transom and rotating transom wherein the rotating transom has a pivot point positioned below both fixed and rotating transoms. The system is provided with a plurality of rotors and tracks to allow the pivot point to be positioned lower than that of prior art systems to allow the boom assembly to more accurately track the contours of row crops in undulating landscapes.

Abstract: A system and method for varying the tread width of a vehicle. The system includes extensible shafts coupled to the wheels of the vehicle. Eccentric cylinders rotate out of frictional locking engagement with the extensible shafts to allow the extensible shafts to be extended or refracted to adjust the tread width of the vehicle. The eccentric cylinders rotate into frictional locking engagement with the extensible shafts to reduce undesired travel of the extensible shafts during vehicle operation.

Abstract: A system and method for raising and lowering a vehicle. The system includes a four-bar linkage provided for each wheel. The four-bar linkage includes a first three linkage assembly and a second three linkages assembly. The first three linkage assembly maintains the orientation of the vehicle relative to the wheel during the lifting and lowering while the second linkage assembly provides the power to lift and lower the vehicle. Power provided by a hydraulic cylinder is pivotably coupled to the second linkage assembly. A steering assembly is provided between the four-bar linkage assembly and the wheel. The four-bar linkage vehicle lifting assembly may be provided on agricultural vehicles, construction vehicles, or any desired vehicle.

Abstract: A system and method for adjusting the tread width of a vehicle. The vehicle has a swing arm on each wheel, each activated by its own hydraulic cylinder. The vehicle's tread can be adjusted by pivoting the swing arms. The swing arms are each provided with two actuators, one to maintain the proper toe angle of the wheels as the swing arms move, and one to steer the vehicle.

Abstract: A system and method for adjusting the tread width of a vehicle. Each wheel of the vehicle is provided with two actuators: one toe actuator to adjust the toe angle and one steering actuator to steer the wheel. The toe actuators and steering actuators counterpose each another. The vehicle is configured to actuate the toe actuators to simultaneously turn the wheels on opposite sides of the frame in opposite directions relative to one another, and to actuate the steering actuators to simultaneously turn wheels on opposite sides of the frame in the same direction as one another.

Abstract: For low height row crops, the system is a toolbar provided with a plurality of depending legs coupled to discs. Provided behind the discs are nitrogen dispensing systems coupled to a large fluid tank provided on a vehicle. By using medium height legs, the system is able to provide material to the soil after crops have emerged, while still allowing a large number of rows of crops to be treated with each application pass.
