  • Patent number: 12044296
    Abstract: A power shift transmission includes a plurality of shafts, a plurality of gears, a plurality of clutches, a plurality of forward modes, and a plurality of alternate forward modes. Each forward mode has a distinct transmission ratio, and each alternate forward mode has a transmission ratio similar to one of the plurality of forward modes.
    Type: Grant
    Filed: January 10, 2022
    Date of Patent: July 23, 2024
    Assignee: DEERE & COMPANY

  • Publication number: 20230118512
    Abstract: A recycling secondary reservoir of a hydraulic system is charged with clean fluid from a primary hydraulic circuit. The secondary reservoir maintains clean fluid for use by a backup pump to cycle a hydraulic device. The secondary reservoir recaptures fluid used by the backup pump to maintain clean fluid that can be reused an indefinite number of times.

  • Patent number: 11585428
    Abstract: Embodiments of a cold start lubricant distribution system include a lubricant distribution circuit, which fluidly interconnects first and second actively-lubricated work vehicle assemblies onboard a work vehicle. A flow divider section is included in the lubricant distribution circuit and through which lubricant flow is apportioned between the first and second actively-lubricated work vehicle assemblies. A lubricant supply pump is further located in the lubricant distribution circuit upstream of the flow divider section. The cold start lubricant distribution system further includes a lubricant flow modification assembly operably in a cold start mode. When operating in the cold start mode, the lubricant flow modification assembly reduces a volume of lubricant flow supplied to the first actively-lubricated work vehicle assembly through the flow divider section relative to a volume of lubricant flow supplied to the second actively-lubricated work vehicle assembly through the flow divider section.
