Abstract: A machine includes a chassis, a plurality of ground engaging elements supporting the chassis above a ground surface, a motor for driving at least one of the ground engaging elements and a plurality of assemblies supporting the chassis on the ground engaging elements. Each of the assemblies is configured to selectively raise and lower the chassis relative to the ground surface and includes a first attachment component for attaching the assembly to one of the ground engaging elements, a second attachment component for attaching the assembly to the chassis, an adjustment component for shifting the first attachment component between a plurality of operating positions relative to the second attachment component. A control system allows an operator to remotely control the adjustment components of each of the assemblies.

Abstract: An assembly for supporting a vehicle chassis on a ground engaging element of the vehicle includes a first attachment component for attaching the assembly to the ground engaging element, a second attachment component for attaching the assembly to the chassis and an adjustment component for shifting the first attachment component between a plurality of operating positions relative to the second attachment component. A suspension component is operably interposed between the first attachment component and the second attachment component is configured to regulate motion transfer between the first attachment component and the second attachment component. The suspension component functions independently of the operating position. A locking mechanism mechanically locks the assembly into any of the plurality of operating positions.

Abstract: 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 chassis, and a suspension component for regulating motion transfer between the wheel attachment component and the chassis attachment component. The chassis attachment component includes a hydraulic rotary actuator for attaching to the vehicle chassis and selectively pivoting the assembly relative to the chassis.

Abstract: An assembly for supporting a vehicle chassis on a wheel of the vehicle includes a frame pivotably connected to the vehicle chassis at a connection location and a wheel attachment component slidingly coupled with the frame. The wheel attachment component is positioned on a first side of the connection location and is configured to pivot in unison with the frame and to move between a plurality of operating positions relative to the frame. A suspension component is positioned on a second side of the connection location opposite the attachment component and is operably interposed between the frame and the attachment component for regulating motion transfer between the frame and the attachment component, the suspension component. An adjustment actuator is rigidly coupled with the frame and is configured to shift the attachment component between any of the plurality of operating positions relative to the frame.

Abstract: 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.

Abstract: A vehicle includes a chassis, a plurality of ground engaging elements supporting the chassis above a ground surface, a motor for driving at least one of the ground engaging elements to thereby propel the machine along the ground surface, and a chassis height adjustment system for selectively raising and lowering the chassis relative to the ground surface. A track width adjustment system is configured to shift the position of at least one of the ground engaging elements laterally relative to the chassis and a controller is configured to automatically actuate the track width adjustment system when the chassis height adjustment system is actuated to preserve a constant track width as the chassis moves up and down relative to the ground surface.

Abstract: A suspension system may be provided. The suspension system may comprise a wheel support idler and a strut. A top end of the strut may be attached to a bottom of the wheel support idler. The suspension system may further comprise a spring configured to absorb shock from the strut. A bottom of the spring may be attached to a top of the wheel support idler. The suspension system may further comprise a first tower and a second tower. The wheel support idler may be configured to slide up and down on the second tower and the wheel support idler may not contact the first tower.

Abstract: A self-propelled, dirigible agricultural vehicle includes a height-adjustable chassis with an axle and a driven wheel hub. The axle is shiftable between a normal clearance position above the wheel hub and a relatively higher elevated clearance position. The chassis further includes a kingpin and a spacer section that is removably connectable to the kingpin. The axle is in the normal clearance position when the spacer is removed from the kingpin and is in the elevated clearance position when the spacer is connected to the kingpin.
