Publication number: 20240174035Abstract: A vehicle includes a frame, a hitch coupled to the frame, a cylinder positioned to move the hitch relative to the frame, the cylinder having a first chamber and a second chamber, and a fluid system fluidly coupled to the cylinder. The fluid system includes an action select valve reconfigurable between a single-acting configuration and a double-acting configuration. The fluid system is configured to supply a fluid to the first chamber to raise the hitch. When the action select valve is in the double-acting configuration, the fluid system controls the cylinder to lower the hitch by draining the fluid from the first chamber and supplying the fluid to the second chamber. When the action select valve is in the single-acting configuration, the fluid system controls the cylinder to lower the hitch by draining the fluid from the first chamber without supplying the fluid to the second chamber.Type: ApplicationFiled: November 29, 2022Publication date: May 30, 2024Applicant: CNH Industrial America LLCInventors: Jerry L. Brinkley, Matthew Klopfenstein

Publication number: 20240175452Abstract: A fluid system includes a reservoir having a first reservoir chamber and a second reservoir chamber separated by a movable barrier, the first reservoir chamber being configured to contain a working fluid. The fluid system includes a piston housing defining an internal volume and a piston movable within the internal volume, the piston separating the internal volume into a first piston chamber and a second piston chamber, the second piston chamber being fluidly coupled to the second reservoir chamber. The fluid system includes a fluid supply configured to provide a control fluid to the first piston chamber.Type: ApplicationFiled: November 28, 2022Publication date: May 30, 2024Applicant: CNH Industrial America LLCInventors: Jerry L. Brinkley, Matthew Klopfenstein, Michelle Lass Sterrett, Joshua Zimmerman, Hossein Gholizadeh

Patent number: 11971029Abstract: A system (100) for testing an agricultural implement includes a frame (106) configured to receive a device (104) to be tested. The frame carries a filter (108), a pump (112), a pressure relief valve (116) in fluid communication with the pump outlet, a frame output tube (122) to deliver the flow of fluid from the pump outlet to the device to be tested, a frame return tube (124) to receive the flow of fluid from the device to be tested, and a recycle flow outlet (128). A method of testing includes connecting a device to the frame output tube and the frame return tube, pumping a fluid from the frame output tube to the frame return tube through the device, and measuring a flow rate of the fluid through the device.Type: GrantFiled: July 7, 2020Date of Patent: April 30, 2024Assignee: Precision Planting LLCInventors: Ben L. Schlipf, Matthew Klopfenstein

Publication number: 20230417260Abstract: A hydraulic system for a vehicle includes a first hydraulic pump including a first displacement actuator and a first pressure port, a first load sense system fluidly coupled to the first displacement actuator, a second hydraulic pump including a second displacement actuator and a second pressure port, a second load sense system fluidly coupled to the second displacement actuator, and a crossover pressure controller coupled between the first pressure port and the second pressure port. The crossover pressure controller reconfigurable between (a) a combined pressure configuration providing fluid communication between the first pressure port and the second pressure port and (b) a separate pressure configuration inhibiting fluid communication between the first pressure port and the second pressure port. The crossover pressure controller is actuatable independent of the first load sense system and the second load sense system.Type: ApplicationFiled: August 24, 2023Publication date: December 28, 2023Applicant: CNH Industrial America LLCInventors: Matthew Klopfenstein, Jerry L. Brinkley

Publication number: 20220364958Abstract: A portable system for testing or demonstrating an agricultural implement includes a case (104) carrying a power supply (206), a plurality of electrical couplers (120) configured to receive wiring harnesses associated with test devices, a simulator module (214) configured to simulate at least one operating parameter of the agricultural implement on which test devices are carried, and a control system. The control system includes a graphical user interface (110) and processing circuitry operably electrically coupled to the graphical user interface (110) and to the wiring harnesses. The processing circuitry is configured to monitor and display information pertaining to operation of the test devices. A method for testing or demonstrating an agricultural implement includes connecting a test device an electrical coupler of the portable system, sending a control signal to the test device, and monitoring performance of the test device with the control system.Type: ApplicationFiled: June 4, 2020Publication date: November 17, 2022Inventors: BEN L SCHLIPF, MATTHEW KLOPFENSTEIN
