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 bucket angle via controller generated commands to a bucket actuator 60 as a function of the angular signals and commands to a boom actuator 60. The controller 100 enables proportional control of the tool angle via a command input device such as an electronic joystick 21. The controller 100 is capable of maintaining an inclination of the tool 36 with respect to the frame 12. If the boom 31 rises to an angle that is equal to or above a predetermined anti-spill boom angle the controller 100 drives the tool via commands to the tool actuator 60 to a tool angle that is equal to or less than a predetermined anti-spill bucket angle.

Automatic and simultaneous retraction of a pair of stabilizer legs for a backhoe loader machine is beneficial for the operator (not shown). Instead of retracting the stabilizer legs by manually holding a pair of control levers continuously in a retract position, the operator (not shown) may simply move the control levers to an auto-retract position. The movement of the control levers in such a manner activates a control switch in connection with each of the control levers. The control switches, in turn, activate a timer relay that activates a solenoid detent operative with each control lever. Once the solenoid detents are in an activated state, the operator (not shown) may relinquish contact with the control levers. The solenoid detents will retain the control levers in the auto-retract position via electro-magnetic forces. The timer relay controls the solenoid detents so that the control levers are retained in the auto-retract position for a preselected time to fully retract the stabilizer legs from any one of a plurality of extended positions.

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 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 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. If either return to dig or a return to carry function while the other is being executed then the two are combined such that return to dig is completed prior to return to carry.

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 generated commands to a tool actuator 61 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 executes a return to carry function. If the boom 31 is at or below the return to carry angle at the time the joystick 21 is moved to the detent position, the controller 100 executes a float function allowing the bucket 36 and the boom 31 to rest on the ground and follow the contours of the earth as the vehicle moves over the earth.
