A wheel-mounting assembly for a utility vehicle includes a chassis and a wheel support assembly mounted to respective outboard ends of first and second telescopic axle assemblies. The first and second telescopic axle assemblies are laterally spaced from one another and are each secured to the chassis. The first and second telescopic axle assemblies each include a respective actuator arranged to control extension and retraction thereof for steering and track-width control.

An assembly for supporting a vehicle chassis on a wheel of the vehicle includes a wheel attachment component for attaching the assembly to the wheel, a chassis attachment component for attaching the assembly to the vehicle chassis, and a suspension component. At least one adjustment element is coupled with the chassis attachment component and with a first portion of the suspension component, and is configured to shift the first portion of the suspension element between a plurality of operating positions relative to the chassis attachment component. A single strut bar is rigidly coupled with the wheel attachment component and with a second portion of the suspension component, and is configured to pivot relative to the chassis attachment component. The suspension component is configured to regulate motion transfer between the wheel attachment component and the chassis attachment component.

An assembly for supporting a vehicle chassis on a wheel of the vehicle includes a wheel attachment component for attaching the assembly to a wheel, a chassis attachment component for pivotably attaching the assembly to a chassis of the vehicle, and a suspension component operably interposed between the wheel attachment component and the chassis attachment component. A first adjustment element is coupled with the chassis attachment component and coupled with a first portion of the suspension component, and a second adjustment element is coupled with the chassis attachment component and coupled with the first portion of the suspension component. The first and second adjustment elements are configured to shift the first portion of the suspension component between a plurality of operating positions relative to the chassis attachment component. A single strut bar slidingly engages the wheel attachment component and is rigidly coupled with a second portion of the suspension component.

An agricultural vehicle includes a chassis, a plurality of ground-engaging elements configured to support the chassis above a ground surface, and a plurality of support assemblies supporting the chassis on the ground-engaging elements. Each support assembly includes a height-adjustment actuator. A controller is configured to adjust the height-adjustment actuators independently of one another and transfer a load from a first ground-engaging element to other ground-engaging elements. A method of operating an agricultural vehicle includes receiving a command to transfer a load from a first ground-engaging element to other ground-engaging elements, adjusting at least one height-adjustment actuator, and transferring a load from the first ground-engaging element to the other ground-engaging elements.

The present invention relates to a bumper system of an agricultural machine, comprising: a plate pivotably connected to a chassis of the machine, movable between an initial position and a contact position; a bar movable between an initial position and an activation position;
the bumper system being configured so that, in the event of the bar coming into contact with an obstacle, the bar moves from its initial position to its activation position, the bar actuating a control member configured to control an emergency sequence of the agricultural machine, the bumper system being further configured so that, in the event of the plate coming into contact with the obstacle, the plate pivots from its initial position to its contact position.
