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 combining the attributes of a tractor and a utility vehicle includes a three point linkage and other locations to which a plurality of attachments for performing grooming or working operations on a ground or turf surface may be couple. The vehicle includes a front mounted engine, a mid-mounted operator compartment and a rear mounted bed or box. A PTO shaft and/or a hydraulic power system of the vehicle power attachments that require power. A control system and a visual display and data entry device linked thereto are provided for allowing an authorized person to setup, store and thereafter use an operational profile for each attachment that is to be coupled to the vehicle. In a rate dependent attachment, the control system maintains the ground speed and the attachment implement in a fixed ratio. A down/up control is used to signal the start and end of an operational sequence to the control system.

A method of operating a vehicle includes receiving at least one of (a) load data indicating a torque on an axle assembly of the vehicle, (b) an indication of a type of an implement that is coupled to the vehicle, or (c) a selection by an operator of an operating mode for the vehicle from a list of operating modes. The vehicle includes a ballast and a ballast actuator that is configured to reposition the ballast. The method further includes controlling the ballast actuator to reposition the ballast based on at least one of (a) the load data, (b) the indication of the type of the implement, or (c) the selection by the operator.

A counterweight for a vehicle includes a housing configured to be coupled to the vehicle. The housing defines an internal cavity configured to selectively receive one or more weights. The housing is configured to be selectively repositionable relative to the vehicle.

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.

A counterweight system includes a bracket and a counterweight. The bracket includes a base configured to couple to a vehicle and at least one arm extending from the base. The counterweight is coupled to the at least one arm. The counterweight is configured to be at least one of (i) pivotally repositionable, (ii) extensionally repositionable, and (iii) translationally repositionable relative to the vehicle.

The invention relates to a method for increasing the load on driving rear wheels (KB, KP) of a tractor during soil cultivation with a farm implement (2), in particular with a plough (20), attached to a three-point linkage (1) of the tractor, in which the vertical position of the attached implement (2, 20) is adjusted relative to the tractor by means of the position of the arms (4) of a lifting device and the length of the upper link (13) of the three-point linkage (1) of the tractor is adjusted. After adjusting the length of the upper link (13) of the three-point linkage of the tractor the axial force acting/induced in the upper link (13) is determined and during travel of the tractor continuously monitored and automatically maintained at the adjusted value, whereby also the adjusted vertical position of the implement (2) attached to the tractor is continuously monitored (2) and is also 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.

In addition, the invention relates to a device for performing the above-mentioned method for increasing the load on driving rear wheels of tractors during soil cultivation.

A counterweight system includes a bracket and a counterweight. The bracket includes a base configured to couple to a vehicle and at least one arm extending from the base. The counterweight is coupled to the at least one arm. The counterweight is configured to be at least one of (i) pivotally repositionable, (ii) extensionally repositionable, and (iii) translationally repositionable relative to the vehicle.

A modular counterweight system includes a housing, a bracket, and an actuator. The housing is configured to selectively interface with a plurality of counterweights, facilitating incremental adjustment of an overall weight of the modular counterweight system. The bracket is configured to couple the housing to the vehicle, and the housing is at least one of (i) pivotally coupled to the bracket, (ii) extensionally coupled to the bracket, and (iii) translationally coupled to the bracket. The actuator is positioned to selectively reconfigure at least one of the housing and the bracket and thereby change the center of gravity of the modular counterweight system.

An additional wheel weight for a utility vehicle includes a weight plate and a retention member configured to be fitted to a wheel rim 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.
