One or more techniques and/or systems are disclosed for a suspended center frame attached to boom wings, and coupled to a fixed center frame. A suspended center frame can be suspended from a fixed center frame with a bearing at a pivot point to allow for pivoting in multiple axes. The suspended frame can comprise one or more dampers that are operably, pivotably coupled with the fixed frame to dampen movement of the suspended frame in the roll axis; and one or more connecting links that are operably, pivotably coupled with the fixed frame to control movement of the suspended frame in the yaw and/or pitch axis. The pivot point can be located above the center of gravity of a suspended portion of the system, and proximate a top portion of the fixed frame; and the links and dampers can be disposed at a bottom portion of the suspended frame.

Pendulum boom suspension

One or more techniques and/or systems are disclosed for a boom suspension system that mitigates roll of respective booms as an associated vehicle rolls from side to side. The exemplary system can comprise a stabilizer bar that couples a left boom to a right boom, by coupling to respective booms' tilt cylinders. The stabilizer bar can be engaged with a central frame, which is fixedly engaged with the vehicle's chassis, through a stabilizer link. The stabilizer link allows the stabilizer bar to move horizontally left and right independently of the left and right movement of the central frame, caused by the vehicle roll. In this way, the inertia of the respective booms allows the stabilizer bar to remain in a substantially neutral position while the central frame, and vehicle, roll from side to side.

Folding spray implements and agricultural work vehicle equipped with folding spray implements are provided. In embodiments, the folding spray implement includes a centerframe assembly, boom assemblies mounted to opposing sides of the centerframe assembly, and an actuation system coupled to the centerframe and boom assemblies. The boom assemblies include, in turn, inner wings pivotally joined to the centerframe assembly for rotation about frame-to-wing fold joints, as well as outer wings pivotally joined to the inner wings for rotation about wing-to-wing fold joints. The actuation system selectively transitions the folding spray implement: (i) from a stowed position in which axes of wing-to-wing fold joints extend principally in horizontal directions; (ii) through an intermediate unfolded position in which the axes of the wing-to-wing fold joints extend principally in vertical directions; and (iii) to a deployed position in which the axes of the wing-to-wing fold joints extend principally in horizontal directions.

Embodiments of a boom system for a work vehicle has a first boom member with a plurality of first boom segments aligned lengthwise to extend along a first boom dimension and a second boom member with a plurality of second boom segments aligned lengthwise to extend in the first boom dimension and spaced from the first boom member in a second boom dimension. The boom system also has a union spanning the second boom dimension to couple the first boom member to the second boom member and having a first coupling segment joining consecutive first boom sections together and a second coupling segment joining consecutive second boom sections together.

An under-frame shield, particularly useful with crop sprayers and other implements which traverse fields of plants, includes one or more flexible sheet material shields connected to axle structure and to a central rigid shield by resilient connectors to facilitate suspension system movement in all directions without sacrificing ground clearance. The connection structure and sheet material shields maintain a smooth, seamless protective surface on the under side of the machine to reduce vehicle and crop damage.

A vehicle is provided with an axle suspended from a main frame of the vehicle by right- and left-hand pairs of connecting rods. As viewed from the top, one of each of the right- and left-hand pairs of connecting rods crosses the other of the pair of rods, and, as viewed from the side, the right- and left-hand pairs of rods are disposed parallel to each other. This arrangement of the connecting rods results in the axle moving substantially vertically up and down during operation of vehicle over uneven terrain.

The working clearance height of a high-clearance vehicle is normally established by four main suspension spindles that are respectively received for reciprocating within upright journals provided at the opposite ends of front and rear axle assemblies of the vehicle main frame, with the bottom end each of the main spindles being received in a bore at the top of an associated wheel motor housing that serves also as a wheel hub mounting bracket. In order to increase the working clearance height of the vehicle, an optional elongate spacer assembly is mounted between the bottom of each elongate main suspension spindle and the associated wheel motor housing. Each main suspension spindle is inclined slightly outwardly relative to a vertical plane extending in the direction of travel of the vehicle and, in order for the spacing between tires at opposite sides of the vehicle to remain the same, with or without the usage of the spacer assemblies, each spacer assembly includes a coupler spindle extending parallel to, and offset inwardly from, a pivot axis of the associated main suspension spindle by a distance calculated to result in the desired tire spacing, this coupler spindle being received in the bore at the top of the associated wheel motor housing.

An agricultural sprayer includes tubular main frame rails supporting tank and plumbing structure. A tank port is located between the rails with a substantial portion of the plumbing structure supported between the rails and between the upper and lower planes of the rails for protection and a neat appearance. The upright walls of the rails include round holes reinforced with round tube secured to the walls to seal the wall and prevent contaminants from entering the rails. The round tube is split to allow torsional frame flexibility while preventing high stress at the round tube sidewall connections. A straight horizontal fluid line path between the port and a location outside the frame is provided through the round tube to limit line length, eliminate elbows, improve appearance, improve cleanout functions and facilitate a low mounting of the tank on the frame.
