An earth-moving vehicle includes a mobile operating arm; at least one actuator for moving the operating arm through a plurality of positions, wherein one of the plurality of positions is a pre-defined reference position; a control for actuating the actuator; and a configuration device. The configuration device includes a sensor designed for detecting at least the pre-defined reference position of the operating arm and for issuing a corresponding position signal, a disabling valve activated automatically according to the position signal to disable actuation of the actuator when the operating arm reaches the predetermined reference position, and a re-enabling switch which can be switched manually by an operator for deactivating the disabling means to enable the actuator to be actuated.
