<p>A backhoe loader (10) with a controller (100) that uses angular signals from at least one sensor to calculate a loader tool angle with respect to the vehicle frame (12) or with respect to the earth and to maintain the loader tool angle via controller (10) generated commands to a tool actuator (60) as a function of the angular signals and commands to a boom actuator (50) The controller (100) enables proportional control of the tool angle via a command input device such as an electronic joystick (21) If the electronic joystick (21) is moved to an appropriate detent position, the controller (100) executes a return to dig function If the bucket (31) is below the return to dig angle at (15) the time the joystick (21) is moved to the detent position, the controller (100) generates commands to move the bucket (36) to the return to dig angle via a curling motion If the bucket (31) is above the return to dig angle at the time the joystick (21) is moved to the detent position, the controller (100) generates commands to move the bucket (36) to the return to dig angle via a dumping motion</p> |
