A swivel bar is operatively connected by a bracket assembly to a toolbar, such that the swivel bar pivots back and forth in the horizontal plane about a pivot. A resilient device is positioned inside the swivel bar where the pivot is combined to the bracket assembly and extends through the swivel bar. At least one agricultural implement and preferably two agricultural implements are connected to the swivel bar on opposite sides of the pivot.

An agricultural implement includes a toolbar system having a toolbar frame, an elevator assembly, and a first wing on one side of the toolbar frame. The first wing may be coupled to the elevator and pivotable about a first vertical axis of rotation between an extended and a folded position. Tools may be coupled to the first wing and rotatable relative to a longitudinal axis of the first wing from an operating position below the first wing to a transport/shipping position above the first wing. Further, the first wing may be adapted to be moveable to position the first wing higher than a wheel of the agricultural implement on the same side of the toolbar frame in the folded position. Subsequently, the tools may be circularly rotated and the middle wing and tools pushed down to reduce the overall width and height of the implement for transporting or shipping.

A lagoon pump may comprise a chassis structure having front and rear ends; a tow bar couple releasably to the front end of the chassis structure; a centrifugal pump couple to the rear end of the structure; a diesel engine fluidly connected to a fuel tank; a clutch rotationally connected to the diesel engine; an extended driveline directly connected to the clutch at one end and to the pump at an opposed end to drive the pump via rotational energy from the diesel engine; a pair of steerable wheels connected adjacent the front end of the chassis structure; and ground engaging wheels connected under the chassis structure between the ends, wherein the ground engaging wheels are both extendable radially outwardly and rotatable axially relative to the chassis structure. A method of mixing and pumping a slurry material from a lagoon or storage pit utilizing such a pump is also disclosed.

Liquid nutrients are continuously applied to a first group of rows of standing crops by pulling a drag hose from a reel located at one end of a field and between two crop rows with a boom having one end pivotally connected to an applicator and a tractor. The boom provides a liquid supply line from the drag hose to the center or one end of the applicator. At the opposite end of the field, the tractor and applicator turn 180° while the boom pivots to project from one end of the applicator to the drag hose. The tractor returns down adjacent rows back to the first end of the field with the boom projecting to the drag hose while the reel simultaneously retracts the hose between the two crop rows. The reel is moved axially to a third group of rows, and the steps are repeated.

A system for controlling nozzle flow rate includes a master node having an expected overall flow rate module configured to generate an expected overall flow rate of an agricultural product based on one or more sprayer characteristics, and an adjustment module configured to generate an error correction based on a difference between the expected overall flow rate and an actual overall flow rate of the agricultural product. A plurality of smart nozzles are in communication with the master node, each of the smart nozzles includes an electronic control unit in communication with one or more control valves and one or more nozzle assemblies. Each of the smart nozzles includes a target smart nozzle flow rate module configured to generate a target smart nozzle flow rate of the agricultural product based on the one or more sprayer characteristics. The target smart nozzle flow rate is adjusted according to the error correction.

An anhydrous ammonia trailer hitch incorporating a base; a vehicle mounting receiver hitch fixedly attached to and extending forwardly from the base; a bolt mounted to the base, the bolt being adapted for moving between latching and releasing positions; a release plate having a first eye fitted for receiving the bolt, the bolt extending into the eye upon movement to the latching position; a remotely actuatable linear motion actuator connected operatively to the bolt for moving the bolt between the latching and releasing position; a tongue mount fixedly attached to the release plate; and at least a first safety chain mount fixedly attached to the release plate.

A method for handling a fluid includes separating the fluid into a liquid and a vapor within a container such that at least a portion of the vapor is disposed above the liquid, detecting a level of the liquid in the container, and actuating at least one valve to exhaust the vapor from the container to maintain the level of the liquid at or above a desired level. The at least one valve is communicatively coupled to a controller. The method further includes sending a signal from the at least one valve to the controller, and determining diagnostic data based at least in part on the signal.

An agricultural implement includes the calibration of liquid fertilizer distribution for an agricultural implement. The calibration system measures the level of the liquid fertilizer or utilizes a known volume in a container and the pressure of the liquid fertilizer. The system uses the level and pressure to calculate the density of the liquid fertilizer, which helps achieve more consistent fertilizer application. Additionally, the density of the liquid fertilizer can be used to more accurately measure the tank level of a particular tank. The system can include a tilt sensor and valves so that when the agricultural implement is traversing a hill or otherwise rough terrain, the system can accurately measure tank level and selectively draw liquid fertilizer from a particular tank or tanks to mitigate spillage. The system also can measure and monitor the tank level of the tank or tanks and automatically fill the tank or tanks based on the measured tank level.

A drawback system is used with a liquid fertilizer distribution system to be used with agricultural implements. The drawback system may include a two-way, reversible pump that allows liquid fertilizer material to be transported from a system source or toward a system source. The drawback system allows liquid fertilizer that is not applied to an agricultural field to be cleared from piping, conduits, and/or other components of a liquid fertilizer system and drawn back into a holding chamber. The drawback system may also comprise a positive displacement pump in communication with a plurality of valves wherein manipulation of the valves can control the direction of the flow of liquid fertilizer, either from or toward a system/fluid source.

A treatment system for spraying treatment fluid onto plants in a field is described. The treatment system includes a highly configurable treatment mechanism including an array of nozzles and valve assemblies coupled into manifolds, and manifold assemblies. The manifolds of the manifold assemblies can be oriented in an open state or a nested state, the open state with no overlap between nozzles of adjacent manifolds and the nested state with overlap between nozzles of adjacent manifolds. The manifolds can have multiple configurations, examples of which include a tube manifold and an offset manifold. The nozzles of the system can have multiple configurations, examples of which include a tri-spray nozzle, a bar nozzle, a fan nozzle, and a deflected fan nozzle. The system can be controlled by a system controller which detects plant material and instructs a nozzle or combination of nozzles to spray treatment fluid.
