  • Patent number: 10145084
    Abstract: A control system for a work machine is disclosed that may include an input device, an electronic controller, and a joystick. The input device may be configured to transmit an electronic selection signal. The electronic controller may be in electronic communication with the input device, be configured to receive the electronic selection signal, and transmit an electronic configuration signal. The joystick may be in operative communication with at least one of a ground engaging member and a work implement and be configured to regulate movement of at least one of these. Further, the joystick may be in electronic communication with the electronic controller and may be configured to move along multiple axes. The joystick may be further configured to receive the electronic configuration signal and be selectively non-movable along at least one of its axes in response to this signal.

  • Patent number: 10061343
    Abstract: An electronic control system for controlling movement of a work machine is disclosed. The control system may include a first and a second joystick, each of the first and second joysticks configured to move between a neutral and an operational position. Moreover a first and second resistive device may be operatively coupled to the first and second joysticks respectively. The first and second resistive devices may be configured to generate a resistive force to selectively retain the first and second joysticks in the operational position. Additionally, the control system may include a controller in communication with the first and second joysticks and the first and second resistive devices. The controller may transmit a first and second resistive force signal to activate one of the first and second resistive devices to generate the resistive force such that one of the first and second joysticks is retained in the operational position.
