A method for optimising the amount of slurry that is spread on a soil to be fertilised by means of a vehicle comprising a slurry spreader device fed by a tank through at least one conduit, wherein the concentration of at least one slurry ingredient in the conduit is acquired, a pressure difference between two points in the feed conduit upstream and downstream of a valve and the speed of the vehicle are measured, an effective volumetric flow rate of the slurry is calculated as a function of the measured pressure difference and a target volumetric flow rate of the slurry is calculated as a function of a target spreading factor and concentration of the ingredient, the measured speed and a spreading width of the slurry spreader device, and the valve is adjusted as a function of the difference between the effective volumetric flow rate and the target volumetric flow rate.

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.

An agricultural implement includes a storage tank, a pump positioned below a bottom portion of the storage tank, and a control system disposed above the bottom portion of the storage tank. The storage tank is configured to hold a flowable agricultural product. The pump is configured to direct the flowable agricultural product out of the storage tank. The one or more controls are configured to control application of the flowable agricultural product.

Land cultivating systems and methods utilizing high-pressure fluid jet cutting techniques are disclosed. An example system includes a mobile unit, a traveler arrangement operably coupled to the mobile unit to ride on the surface of stubble residues as the mobile unit moves across land to be cultivated, and a fluid jet cutting head supported by the traveler arrangement. The cutting head is configured to selectively discharge a high-pressure fluid jet to make a cut through the stubble residues and underlying soil as the mobile unit moves across the land. A soil opening device is provided to form a furrow in the ground in line with the cut made by the high-pressure fluid jet, and a liquid injector nozzle is provided to discharge fertilizer or other chemical(s) into the soil.

A system for changing pressure in one or more tires of a self-propelled agricultural machine according to a load differential determined using load sensors on opposing locations of the machine. A load differential may be caused by a disproportionate distribution of forces and/or weight on the machine. Load sensors proximal to the tires may allow determining corresponding loads on the tires and, in turn, the load differential. As a result, tires experiencing greater loads may be inflated, whereas tires experiencing lesser loads may be deflated. In addition, a Human Machine Interface (HMI) may be provided in the operator cab to allow an operator to have further control over tire inflation on the fly while operating the machine.

Each wing of a rear folding implement has a wing frame supported on rear wheels for movement along the ground, and a forewing frame and wheel pivotally attached to the wing frame. A center ball joint pivotally connects right and left inner wings and a center wheel assembly supports the center ball joint. The wings extend laterally and the forewing frames are in a lowered position supported on their wheels when in the operating position. To move the wings into a transport position, the implement is towed forward and the wings pivot about the center ball joint to trail rearward and the forewing frames are moved upward to narrow the implement for transport. An air seeder cart hitch is rearward of and near the center ball joint in the operating position, and when the wings trail rearward the cart hitch is near rear ends of the trailing wings.

A turf sprayer comprises a transport vehicle that carries a laterally extending spray boom assembly. The spray boom assembly is both laterally displaceable and angularly displaceable relative to the transport vehicle. A controller uses a defined path represented by GPS coordinates to control the operation of various actuators to automatically maintain a reference point on the spray boom assembly on the desired path and to automatically maintain the spray boom assembly perpendicular to the desired path.

Systems, methods, and apparatuses for applying specially formulated spray materials. The feedstock for the spray materials includes one or more immiscible materials. To mix immiscible materials at low pressure, the materials are applied from separate inputs of a fixture to separate channels where they are permitted to flow to and spread over surfaces or edges at selected thicknesses. On the surfaces or edges the materials are each subject to flowing air that forms small particles or drops even though the materials may be viscous. The particles or drops are mixed together and may be applied to a combustion device or spray device or any other device utilizing the mixture.
