Abstract
A backhoe loaderwith a controllerthat uses angular signals from at least one sensor to calculate a loader tool angle with respect to the vehicle frameor with respect to the earth and to maintain the loader tool angle via controller generated commands to a tool actuatoras a function of the angular signals and commands to a boom actuator. The controllerenables proportional control of the tool angle via a command input device such as an electronic joystick. If the electronic joystickis moved to an appropriate detent position, the controller executes a return to carry function. If the boomis at or below the return to carry angle at the time the joystickis moved to the detent position, the controllerexecutes a float function allowing the bucketand the boomto rest on the ground and follow the contours of the earth as the vehicle moves over the earth.
