A chassis, particularly for self-propelled operating machines, has a frame adapted to support a motorized movement means and a control means of an operating machine. The particularity of the present invention resides in that it comprises at least one ballast member adapted to support mechanical parts of the operating machine, which is an integral part of the frame.

A vehicle includes a frame, a first axle assembly coupled to the frame and including a first pair of tractive elements, a second axle assembly coupled to the frame and including a second pair of tractive elements, a prime mover coupled to the frame and configured to drive the first axle assembly and the second tractive assembly to propel the vehicle, a ballast movably coupled to the frame, and a ballast actuator configured to reposition the ballast relative to the frame to shift a center of gravity of the vehicle relative to the first axle assembly and the second axle assembly.

An automatic steering system and method for an articulated work vehicle having a front wheel steering system supported by front wheels at a front frame and a rear frame supported by rear wheels rotatably coupled to the front frame at an articulator. A controller operatively connected to the front wheel steering system and to the articulator adjusts wheels of the front wheel steering system along a path and moves the articulator to direct the rear frame in response to a steering signal. The steering signal directs the vehicle in a minimum turn radius mode or a controlled traffic control mode. In the minimum turn radius mode, the rear wheels do not follow the tracks of the front wheels when making a turn. In the controlled traffic mode the rear wheels follow in same tracks as the front wheels.

A work vehicle includes: a body frame; a front weight at a front end portion of the body frame; a support mechanism supporting the front weight in such a manner that the front weight is movable in a front-back direction relative to the body frame; and a drive actuator configured to move the front weight in the front-back direction relative to the body frame between (i) a back position, at which the front weight is close to the body frame, and (ii) a front position, at which the front weight is far from the body frame.

A tractor hydraulic adaptor, system and process to hydraulically power a hydraulic attachment on a tractor is disclosed. The hydraulic adapter includes a hydraulic intensifier powered by a tractor's power take off shaft to drive a hydraulic attachment coupled to a tractor's front-end loader. The hydraulic intensifier draws at a low-pressure hydraulic fluid and feeds the hydraulic fluid at a higher pressure to the hydraulic attachment.

An automatic steering system and method for an articulated work vehicle having a front wheel steering system supported by front wheels at a front frame and a rear frame supported by rear wheels rotatably coupled to the front frame at an articulator. A controller operatively connected to the front wheel steering system and to the articulator adjusts wheels of the front wheel steering system along a path and moves the articulator to direct the rear frame in response to a steering signal. The steering signal directs the vehicle in a minimum turn radius mode or a controlled traffic control mode. In the minimum turn radius mode, the rear wheels do not follow the tracks of the front wheels when making a turn. In the controlled traffic mode the rear wheels follow in same tracks as the front wheels.

A combination air supply system for a work vehicle, includes a work vehicle compressor configured to be mounted on the work vehicle, wherein the work vehicle compressor is configured to compress a first supply of ambient air and to output a first compressed air supply via a compressed air line, wherein the compressed air line is configured to receive a second compressed air supply from an implement compressor via a compressed air connection line, wherein the implement compressor is configured to be mounted on an implement towed by the work vehicle, wherein the compressed air connection line is configured to couple the implement compressor to the compressed air line via a coupler, and a tire inflation system fluidly coupled to the compressed air line and configured to selectively increase and decrease an air pressure within a tire of the work vehicle, wherein the tire inflation system is configured to distribute the first compressed air supply, the second compressed air supply, and a combination air supply of the first and second compressed air supplies to the tire.

An additional wheel weight for a utility vehicle includes a weight plate and a retention member configured to be fitted to a wheel and on which the weight plate is guided in a longitudinally axial manner. A clamping lever closure is disposed between the weight plate and retention member. A first assembly element of the clamping lever closure is coupled to the retention member, a second assembly element of the clamping lever closure engages the weight plate in a longitudinally axial manner, and a lever mechanism is disposed between the first and second assembly elements. The lever mechanism includes a clamping element being releasably secured to the first assembly element and an actuation lever being articulated between the second assembly element and the clamping element.

A method for increasing the load on driving rear wheels (KB, KP) of a tractor during soil cultivation with a farm implement (2), attached to a three-point linkage (1) of the tractor. A vertical position of the attached implement (2, 20) is adjusted relative to the tractor by a position of the arms (4) of a lifting device and by adjustment of the length of the upper link (13) of the three-point linkage (1) of the tractor. After adjusting the length of the upper link (13), the axial force acting/induced in the upper link (13) is determined and during travel of the tractor is continuously monitored and automatically maintained at the adjusted value. Also the adjusted vertical position of the implement (2) attached to the tractor is continuously monitored (2) and is automatically maintained at the adjusted value, thereby maintaining the vertical position of the attached implement (3) in this regulation and thus also constant ploughing depth.

Systems and methods for towing a bagging machine are disclosed. The system includes a coupler connected to a hopper that is configured to raise and lower relative to a chassis of the bagging machine. The chassis has at least six wheels in contact with the ground that remain in contact with the ground when the coupler is attached to a towing vehicle hitch. The hopper raises to attach the coupler to the hitch and lowers to engage the hitch for towing, while keeping the wheels on the ground.
