The present invention discloses a formulation and an apparatus for spraying a biopesticide against corn borer and other crop pests.

A trailer brake system that generates load-dependent braking forces. Variable trailer load information is used to generate load-dependent control signals which serve to control an electrically-controlled proportional valve. A load sensing valve serves to modify brake command signals in dependence on a control pressure that is regulated by the proportional valve.

A method and apparatus for mounting a pump stack in a self-propelled agricultural product applicator utilize a pump stack mounting arrangement including a pump stack, a crossmember with a web having an opening providing clearance for passage through the opening of at least one successive pump of the pump stack, and a removable mounting plate adapted for attachment to the crossmember and the at least one successive pump on an opposite side of the crossmember from a proximal end of the pump to provide support for a distal end of the pump stack. By removing the mounting plate, detaching any successive pump in the stack from its immediately preceding pump in the pump stack, and moving the detached part of the pump stack axially through the opening, clearance is provided for servicing a pump in the stack without removal of the whole pump stack or the crossmember.

A closure arrangement for a tank includes a tank lid and an opening flange. The opening flange has first and second tank flange lips spaced by an offset distance. The tank flange lips extend toward one side of the tank. The tank has a lid flange with first and second lid lips spaced by an offset distance corresponding to the offset distance. The lid lips extend, at least in part, toward a second side of the tank. The lid lips include first and second walls arranged at a tank interior side of the respective first and second tank flange lips in an offset direction. When the tank lid is closed over the tank opening, one or more seals engage the tank flange lips from the tank interior side and engage the lid lip walls of the lid flange from an exterior side of the tank in the offset direction.

The invention relates to a device for preparing aqueous solutions intended to be sprayed via a manifold including two or more nozzle sections, on a surface from a mixture of water and two or more additives. Said device includes: a water vessel (2); a pump (6) connected to each section (4, 5); a first pipe (8) connecting the water vessel (2) to the pump (6); a second pipe (9) with as many parallel arms between the pump (6) and each section (4, 5); at least two additive vessels (10, 11); anda means (12) for metering the amount of each additive that is to be injected into the second pipe (9) and mixed with the water.

A liquid distribution system for a crop sprayer includes a product tank configured to contain a liquid, a pump in fluid communication with the product tank, a plurality of nozzles carried by a boom and configured to receive the liquid from the pump, a recirculation line connecting the plurality of nozzles to the product tank, and a bypass line connecting the pump to the product tank. The recirculation line includes an on/off valve configured to alternatively block or permit flow through the recirculation line. The bypass line includes a second on/off valve configured to alternatively block or permit flow through the bypass line. Related crop sprayers and methods are also disclosed.

An agricultural vehicle includes a chassis, a plurality of ground-engaging elements, and a liquid holding tank. The liquid holding tank includes a first bladder disposed within an interior of the liquid holding tank, the first bladder defining a first chamber within the first bladder, and a second chamber defined between a wall of the liquid holding tank and an outer surface of the first bladder. A method of forming a liquid holding tank of a vehicle includes disposing a first bladder within an interior of the liquid holding tank, a first chamber being defined within the first bladder and a second chamber being defined between an inner wall surface of the liquid holding tank and an exterior of the bladder, and causing both of the first chamber and the second chamber to be in fluid communication with a delivery system of an application system of the vehicle.

A method for applying two different sprays to agricultural land using an agricultural spraying device that includes a first spray circuit having a first spray tank and a first spray nozzle unit, and includes a second spray circuit, which is fluidically separate from the first spray circuit and has a second spray tank and a second spray nozzle unit. The method includes providing a first spray in the first spray tank. The method also includes providing a second spray in the second spray tank. The method also includes applying either the first spray using the first spray nozzle unit or the second spray using the second spray nozzle unit to field portions of the agricultural land depending on whether the at least one defined weed is present in each field portion.

An agitation pressure control system in an agitation system of an agricultural vehicle includes a first valve in an agitation line and a second valve in a spray line, the spray and agitation lines being fluidly connected to a hydraulic pump via a T connection.

An agricultural sprayer includes an actuator configured to adjust the position of a boom assembly of the sprayer relative to a frame of the sprayer. A computing system is configured to determine the operating parameter of the sprayer at a current time based on received sensor data. Moreover, the computing system is configured to anticipate when the boom assembly will move relative to the frame in a fore/aft direction at a future time based on the determined operating parameter, with the fore/aft direction being parallel to a direction of travel of the agricultural sprayer. In addition, when it is anticipated that the boom assembly will move, the computing system is configured to control the operation of the actuator before the future time such that movement of the boom assembly relative to the frame is reduced at the future time.
