Abstract
A backhoe loader with a controller that uses angular signals from at least one sensor to calculate a loader tool angle with respect to the vehicle frame or with respect to the earth and to maintain the loader tool angle via controller generated commands to a tool actuator as a function of the angular signals and commands to a boom actuator. The controller enables proportional control of the tool angle via a command input device such as an electronic joystick. If the electronic joystick is moved to an appropriate detent position, the controller executes a return to carry function.
