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.
