Publication number: 20230265864Abstract: An auxiliary hydraulic system including an accumulator, a control valve, and a hydraulic connector. The accumulator connects to a primary hydraulic system including a hydraulic pump, a brake circuit, and a steering circuit. The control valve selectively allows or prevents flow from an accumulator to at least one of the brake circuit and the steering circuit. The hydraulic connector selectively connects an external source to the accumulator and the control valve.Type: ApplicationFiled: February 21, 2022Publication date: August 24, 2023Inventors: JEFFREY L.

Publication number: 20230264665Abstract: A brake pedal feedback system includes a spring driver, a first spring, a first brake pedal, and a second brake pedal. The spring driver includes a first recess and a second recess. The first brake pedal includes a first extension at least partially positioned in the first recess. The second first brake pedal includes a second extension at least partially positioned in the second recess. When the first brake pedal is in an engaged position and the second brake pedal is in a disengaged position, the first extension contacts a first surface of the first recess causing the spring driver to move the first spring from a relaxed condition to an energy storing condition, and the second extension is spaced apart from a first surface of the second recess.Type: ApplicationFiled: December 19, 2022Publication date: August 24, 2023Inventors: JEFFREY L.

Patent number: 11702136Abstract: Vehicles, control systems for vehicles, and methods of operating vehicles are disclosed herein. A vehicle includes a frame structure, a front section, a rear articulation section, and a control system. The front section is coupled to the frame structure and to a front plurality of wheels supported for movement on a front axle. The rear articulation section is coupled to the frame structure and to a rear plurality of wheels supported for movement on a rear axle. The rear articulation section is pivotally coupled to the front section via an articulation joint and arranged opposite the front section along a vehicle axis. The control system is coupled to the frame structure and includes a mode selector configured to provide input indicative of a mode selected by an operator in use of the vehicle and a controller communicatively coupled to the mode selector.Type: GrantFiled: September 18, 2019Date of Patent: July 18, 2023Assignee: DEERE & COMPANYInventors: Scott A. Hudson, Jeffrey L. Lubben, Jeffrey M. Tott

Patent number: 11698122Abstract: A drive system includes a planetary gear set having first and second rotatable input members connected in driven relation with respective first and second power sources, and a rotatable output member connected in driving relation with a working piece, the first and second rotatable input members being connected in differentially rotatable communication with the output member. The input members are operable to vary the rotation and direction of the output member and the connected working piece. In an aspect, the output member is rotatable about an axis for driving the working piece, and the first and second input members are also rotatable about the axis. In a further aspect, the first and second input members include coupling regions for coupling the first and second power sources on-axis with the drive system. In a further aspect, the second power source is a hydraulic input motor concentric with the first input member.Type: GrantFiled: October 22, 2020Date of Patent: July 11, 2023Assignee: Deere & CompanyInventor: Jeffrey L.
