  • Multiple mode operational system for work vehicle braking
    Patent number: 7233853
    Abstract: A work vehicle includes a multiple mode operational system having a work system such as a linkage and associated hydraulic cylinders of a backhoe, a braking system and a multiple mode control system. The multiple mode control system includes a central controller, a mode toggle switch and a work system control device such as an electromechanical joystick. The central controller is capable of entering at least a first operational mode and a second operational mode. In the first operational mode, the central controller manipulates the work system based on signals received from the work system control device. In the second operational mode, the central controller controls the braking system based on signals received from the work system control device.
