A vehicle includes a chassis, ground-engaging elements configured to support the chassis, support assemblies supporting the chassis on the ground-engaging elements, adjustable axles configured to change a lateral distance from the chassis to each of the support assemblies, and a controller configured to move the chassis laterally along the axles without changing a track width between ground-engaging elements on opposing sides of the chassis. Disclosed methods may be used to remove and install application systems on the vehicle.

A tandem wheel assembly for a work vehicle includes a tandem wheel housing, a center drive member rotatably disposed within the housing, first and second wheel end assemblies, a coupler between each wheel end drive member and the center drive member, and a brake assembly. Each wheel end assembly includes an input shaft, a wheel end drive member mounted thereon, a wheel end gear train coupled to the input shaft, an output shaft coupled to the wheel end gear train, and a wheel end hub coupled to the output shaft for supporting one of the wheels. The brake assembly is coupled to the tandem wheel housing and to the input shaft or the output shaft of at least one of the first wheel end assembly or the second wheel end assembly and reduces the amount of backlash.

Systems and methods relating to the replacement of specific parts in farm equipment to thereby adjust the farm equipment's capabilities. To modify the ground clearance of farm equipment, especially sprayers with a strut type suspension, the spindles of the suspension system along with the air spring absorber are replaced. The original spindles are replaced with longer spindles while the air spring absorber is replaced with one that allows for an increased range of travel. As well, the fixed length linkage arms that connect the air height control valves to the suspension system may be replaced with longer arms. These longer linkage arms may be of a fixed length or they may be of an adjustable length. Alternatively, a replacement bracket may be used to allow for the reuse of the original linkage arm.

The invention relates to a load-carrying vehicle part with a first and a second wheel pair (10, 11), which are suspended in a respective bogie element (20) on each side of a frame member (14), a suspension (15) between each bogie element (20) and the frame member (14) on each side of the vehicle part to manipulate the frame member relative to the respective wheel pairs (10, 11), or support the frame member in a springing manner, each suspension (15) comprises a first and a second rocker arm (26A, 26B), wherein the first rocker arm is located in front of the second rocker arm viewed in the normal forward direction of driving of the vehicle part, that each rocker arm (26A, 26B) with its one end is pivotably in a joint (27, 27) in the frame member (14) and with its other end is pivotably in a joint (28, 28) in the bogie element (20) a first spring leg (25A) and a second spring leg (25B), wherein each spring leg with its one end (30) is articulately fastened to the frame member (14) and with its other end (31) is articulately fastened in a rocker arm (26A, 26B), a motion conversion arrangement (29) capable of converting a rotary motion in a joint (27, 28) for one of the rocker arms (26A, 26B) to a forward and backward translation motion.

A plurality of traveling wheels are supported via expandable/contractible tubular support members to a vehicle body frame. A hydraulic operation type vehicle height adjustment mechanism provided for each one of the traveling wheels, the vehicle height adjustment mechanism being capable of switching a relative height of the traveling wheel relative to the vehicle body frame within a predetermined length range by expanding/contracting the support member by a hydraulic cylinder. There are provided a hydraulic control valve capable of controlling feeding state of work oil to each one of the plurality of hydraulic cylinders, a controlling section for controlling an operation of the hydraulic control valve to bring the vehicle body to a target state via vehicle height adjustment by the hydraulic cylinder in response to a change in the posture of the vehicle body and a plurality of accumulators connected oil chambers of the respective plurality of hydraulic cylinders.

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.

The invention provides a pneumatic conveying system for an agricultural product applicator, which system comprises multiple fans configured to serve separate boom sections of the applicator to more efficiently conduct airflow with respect to each section. In aspects of the invention, multiple centrifugal fans of the same or similar size can be used, or multiple centrifugal fans of various sizes can be used, such as one or more larger fans and one or more smaller fans. Exemplar aspects could include three small or medium sized centrifugal fans, four small or medium sized centrifugal fans, and five small or medium sized centrifugal fans, thereby allowing the system to raise outlet air pressure at an elevated flow. Another aspect of the invention could include configuring one fan to supercharge another fan, in series, also allowing the system to raise outlet air pressure at an elevated flow.
