Abstract: A boom assembly for an agricultural applicator includes a frame supporting a boom arm pivotably coupled to the frame and rotatable about a first axis. A first actuation assembly is pivotably coupled to the frame and the boom arm at a first pivot point for rotation about a second axis on a first side of the first axis. A second actuation assembly is pivotably coupled to the frame and the boom arm at a second pivot point for rotation about a third axis on a second side of the first axis. A sensor is configured to detect data indicative of a relative position of the boom arm relative to the frame. A computing system is configured to activate at least one of the first actuation assembly or the second actuation assembly in response to determining that the boom arm has deviated from a predefined angular range.

Abstract: A suspension assembly for the spray boom of work vehicles, such as sprayers, self-propelled or not, is formed by an upper shock absorber sub-assembly that comprises a first spring and a second spring responsible for connecting the support frame and the support, respectively in their side portions, being further formed by a lower shock absorber sub-assembly comprising a third spring and a fourth spring, which connect the lower portions of said support frame and said support.

Abstract: A boom assembly is provided herein that includes a mast configured to couple with a work vehicle. A frame supports first and second boom arms extending from opposing side portions of the frame. Each of the first and second boom arms are configured to move between a folded position and an unfolded position. A hydraulic suspension is operably coupled to the frame and the mast. The hydraulic suspension includes first and second actuators configured to mechanically interconnect opposing side portions of the frame to the mast. The hydraulic suspension further includes a damping assembly positioned in fluid communication with the first and second actuators and can provide various damping levels to the boom assembly.

Abstract: In one aspect, a system for controlling the torsional output of a hydrostatic transmission of a work vehicle may include pilot-operated first and second valves. The first valve configured to be actuated to a closed position to occlude fluid flow through a first fluid conduit when a pressure within such conduit at a location downstream of the first valve drops below a first threshold. Moreover, the second valve configured to be actuated to a closed position to occlude fluid flow when a pressure within the second fluid conduit at a location downstream of the second valve drops below a second threshold. As such, when one of the first or second valves is actuated to the closed position, an increased flow of fluid is delivered through the other of the first valve or the second valve to increase a torsional output of an associated hydraulic motor.
