An earth moving machine comprises a vehicle ( 2 ), a working device ( 10 ) mounted on the rear part ( 4 ) of the vehicle ( 2 ), a seat ( 14 ) rotatably attached to the vehicle ( 2 ) and able to rotate between a front position in which it is facing the front part ( 3 ) of the vehicle ( 2 ) and a rear position in which it is facing the rear part ( 4 ) of the vehicle ( 2 ), driving means ( 15 ) for the vehicle ( 2 ), and means ( 19 ) for moving the working device ( 10 ). The machine ( 1 ) also comprises a sensor ( 22 ) attached to the seat ( 14 ) to detect its position and enabling means operatively connected to the sensor ( 22 ) and to the movement means ( 19 ) for enabling operation of the movement means ( 19 ) at least when the seat ( 14 ) is in the front and rear positions, and for inhibiting operation of the movement means when the seat ( 14 ) is in at least one intermediate position between the front and rear positions, thus there being detected, during rotation of the seat ( 14 ), at least a front enabling zone ( 23 ) and a rear enabling zone ( 24 ) in which the movement means ( 19 ) are enabled, and at least one side inhibit zone ( 25 ) in which operation of the movement means ( 19 ) is inhibited.
