An operator can interact with a user interface to input tire configuration information for a tires installed on an agricultural machine so that a control system of the machine can accurately apply information about the tires to display calculated parameters and/or control machine functions. In one aspect, the input could correspond to custom information for tires which the controller could use to derive tire dimensions, such as a rolling circumference of the tire, for calculating parameters. In another aspect, the input could correspond to a selection among several predetermined tire configurations. The controller can then apply the tire dimension to calculate one or more parameters, such as speed and/or distance traveled, for display, and/or to control various machine functions, such as an agricultural product application rate, steering, driveline and/or suspension control.

A deflectable touchdown wheel system for a sprayer boom of an agricultural sprayer is provided that includes a touchdown wheel that deflects transversely when contacting the ground at an angle, damping ground contact impact forces at the sprayer boom reducing reactionary forces such as external steering inputs at the sprayer vehicle.

A first leg extends upward from the left frame and a second leg extends upward from the right frame to connect the legs to the beam. One or more satellite navigation receivers are associated with beam to determine a position and an attitude of the beam. One or more row units are suspended from the beam, such that the position of nozzle or nozzles on each row unit can be adjusted simultaneously and dynamically in multiple dimensions to maintain a target spacing between the nozzle and ground and the nozzle and a plant or row of plants.

In one embodiment, an apparatus, comprising: a housing; a spherical bearing disposed within the housing; a shaft disposed in part beneath the housing and penetrating a portion of the spherical bearing; a bellow circumscribing a lower portion of the housing and providing an interface between the spherical bearing and the shaft; and a cover adjacent a lower end of the bellow and having a circumferential groove configured to enable rotational movement of the bellow, the cover extending to and circumferentially surrounding a portion of the shaft to seal the shaft.

An apparatus for spraying flowable media and in particular plant protection agents onto plants, has at least a first spray unit and a second spray unit wherein each of the spray units has a tubular conduit unit that extends in a predetermined longitudinal direction and is suitable and intended for conducting a flowable plant protection agent, and wherein each of the spray units has at least one spray head that is in flow communication with the conduit unit associated therewith

The spray units are provided in a pivotable manner in relation to a predetermined pivot axis on a carrier, and the apparatus has an adjustment unit that allows both the first spray unit and the second spray unit to be pivoted between a working position and an idle position.

A front-boom sprayer is provided that includes a boom center section and lift arm arrangement that provides a field of view below the boom when the boom is in a raised state that is substantially free of view obstructions from torque tube or other crosswise-extending components. The lift arm arrangement may provide different link tube geometries so that the respective left and right pairs of upper and lower lift arms align with each other in the line of sight of the in-cab operator.

A sprayer boom support for an agricultural sprayer including two articulated arms that are coupled in an articulated manner on both sides of the sprayer, wherein each articulated arm is comprised of bar sections that are formed in a composite material consisting of a reinforcing agent chosen from carbon fibre, fibreglass, aramid fibre, boron fibre or a combination thereof, and a matrix of epoxy, vinyl ester, phenolic or polyester resin, the bar sections having a tube geometry with a substantially rectangular cross section with rounded vertices and arched sides, the length of two of its equal sides being constant along the bar section.

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.
