  • CONTROL SYSTEM FOR ACTUATED PINS
    Publication number: 20230313486
    Abstract: An actuated shear pin includes an actuator and pin body coupled to the actuator. The actuator selectively configures the pin body in a locking configuration or a stowed configuration. In the locking configuration, the pin body is placed in a travel path of two components configured to move relative to each other, to inhibit such relative movement. In the stowed configuration, the pin body is out of the travel path, thereby allowing the two components to move relative to each other.

  • Variable system pressure based on implement position
    Patent number: 11680381
    Abstract: A hydraulic system for controlling an implement on a work machine may include a hydraulic reservoir, a hydraulic pump in fluid communication with the reservoir, a central valve in fluid communication with the pump and configured for controlling the implement, a load sense pressure relief system, and a controller. The controller may be configured for controlling the central valve and the load sense pressure relief system and selecting between operating the hydraulic system at a first pressure and a second pressure based on a factor relating to implement position.

  • Variable system pressure based on implement position
    Patent number: 11661723
    Abstract: A hydraulic system for controlling an implement on a work machine may include a hydraulic reservoir, a hydraulic pump in fluid communication with the reservoir, a central valve in fluid communication with the pump and configured for controlling the implement, a pressure relief system arranged in fluid communication with the hydraulic pump and the central valve, and a controller. The controller may be configured for controlling the hydraulic pump, the central valve and the pressure relief system and selecting between operating the hydraulic system at a first pressure and a second pressure based on a factor relating to implement position.
