Abstract: The present invention relates to a mobile vehicle, in particular for cutting lawns or gardens, comprising a support frame (3), a driving station (4), at least one work tool (5) carried below by said support frame (3) for performing a process on land to be maintained, and a command device (7), such as a joystick, operable by the operator seated in said driving station (4), for determining a movement of the vehicle. The vehicle comprises a right drive wheel and a left drive wheel as well as a first and a second electric motor (9a), independent of each other, coupled to the first and the second wheel respectively and powered by a battery pack (10); a controller (50) is configured for receiving at least one command signal from the command device (7) and consequently commanding the two electric motors. In one aspect, the controller (50) can, upon detection of emergency signals, command the locking of the electric motors active on the wheels, and of the electric motor(s) active on the work tool (5). In a further aspect, an emergency brake managed by the controller (50) is included on each of the crankshafts of each of the electric motors.
