A system for actuating a sensor of an agricultural sprayer may include a boom assembly and a sensor assembly supported on a portion of the boom assembly. The sensor assembly may include a field sensor movable relative to the portion of the boom assembly between an extended position and a retracted position, where the field sensor generates data indicative of one or more field conditions when in the extended position. The sensor assembly may further include a sensor actuator that moves the field sensor between the extended and retracted positions, and a controller that controls the sensor actuator to move the field sensor between the extended and retracted positions. The field sensor is spaced relative to the portion of the boom assembly by a larger distance when in the extended position than when in the retracted position.

A foldable rear boom section of an agricultural product applicator includes at least one first tube connected to a first end of a respective at least one second tube and a hinge assembly coupled to the first and second tubes and configured to pivot the second tube with respect to the first tube about a pivot axis. Further, a nozzle is connected to a second end of the second tube. Pivoting the first and second tubes about the pivot axis causes the foldable rear boom section and the nozzle to transition between an extended position and a retracted position.

A system, an apparatus and a method for uniformly applying UAN fertilizing liquid to soil on farmland for the purpose of increasing crop yields. The system has an UAN sprayer distribution rail applicator apparatus which may be pulled behind a tow vehicle or pushed by a sprayer or fertilizer applicator. The atmospheric tank contains UAN fertilizing liquid which passes from a pump, through a safety shut-off valve, and through a turbine style flow meter. A safety bypass line is provided upstream of the flow meter to relieve unsafe hydraulic pressure back through a pressure-sensitive valve in the event that multiple control valves close simultaneously. Flow through this bypass line also provides mixing of the UAN fertilizing liquid during cold weather. Upon exiting the flow meter, the UAN fluid enters the center of a distribution rail assembly. Spray nozzles with individual automatic shut-off valves are spaced across the distribution rail assembly.

The invention relates to an agricultural apparatus (1) for spreading material, such as fertilizers, plant protection products, or seed, comprising a distributor linkage (10) which can be folded on both sides, comprising a central part (11), where the central part (11 ) is connected in a rotationally fixed manner to the agricultural apparatus (2 ), two intermediate frames (12a,b) connected to the central part (11) in particular by joints, two lateral booms (13a,b) connected to the respective intermediate frames (12a,b), and a damping assembly (19) for damping motions of the first boom (13a) and the second boom (13b) in the direction of travel of the agricultural apparatus (1), where the damping assembly connects the intermediate frames (12a,b) to one another in particular independently of the central part (11), or where the damping assembly (19) connects the respective intermediate frames (13a,b) to the central part (11).

An improved agricultural spray boom having a primary section, a secondary section and a break away section is provided. The primary section has a top extrusion having a web and two tubes, each tube having a heat sink and a wing. No welds are located above the centerline of the tubes where stress would be the greatest. The secondary section is pivotally attached to the primary section. Weight of the second section and break away section cause a twisting force to be applied to the primary section. The primary section has specially oriented side braces which act in compression to resist the twisting force. The primary section further has a steel connector connected to the underside of the extrusions (and not welded to top of extrusions). The secondary section also has a top extrusion with a web and two tubes.

A hinge system is provided for a boom of an agricultural product applicator that facilitates a compact folded boom width in a transport mode by providing a multi-directional folding, including folding with compound movement components to reorient a primarily horizontal stack of boom sections to a primarily vertical stack of the boom sections, when fully folded. The hinge system may include multiple hinge joints with pivot axes that are oriented at different angles to allow for substantially horizontal folding movements followed by a rolling-type movement(s) that reorients a generally horizontal stack of boom sections into a generally vertical stack of boom sections to decrease an overall width of the applicator when in transport mode.

An agricultural implement includes a frame having a longitudinal axis and laterally opposed sides and motive supports mounted to and supporting the frame. The agricultural implement further includes a first wing carried by the frame and at least one second wing, in which each second wing is pivotably connected to the first wing. The agricultural implement also includes an elevator mechanism configured to raise and lower the first wing and the second wing. Each second wing is connected to the first wing by a wing pivot assembly that includes a skewed hinge pivotably connecting one of the second wings to the first wing. The wing pivot assembly allows each second wing to pivot with respect to the first wing between an operating position and a transport position, in which the skewed hinge defines a first pivot axis oriented at an acute angle with respect to the longitudinal axis.

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.

Described herein are implements and application units for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, an application unit includes a frame to be positioned in operation between two rows of plants and a plurality of flexible members coupled to the frame in operation such that the plurality of flexible members guide a lateral position of the frame to be approximately equidistant from the two rows of plants based upon whether at least one flexible member of the plurality of flexible members contacts one or more plants of the two rows of plants. The plurality of flexible members include a plurality of fluid outlets for spraying crop input in close proximity to the rows of plants.

An articulated nozzle-holder boom arm for agricultural sprayer which is extensible to the sides of a main chassis and which can be folded to a transportation position by means of an intermediate hinge generally placed in an intermediate point of the boom arm, and the several sections of the beam forming the boom arm can be engaged or disengaged easily and without welding in the hinge or several supports of the beam sections, being the beam sections generally extruded aluminum profiles and the union of the profiles ends obtained engaging the same in retaining flanges included in the supports and hinges of connection of the sections.
