A working machine comprising: a body; a working arm attached to the body; a working implement attached to a distal end of the working arm; a drive arrangement for propelling the working machine, where the body is rotatable with respect to the drive arrangement; and a joystick assembly comprising: a controller configured and arranged to control a plurality of working machine functions; a first electronic joystick in communication with the controller; and a plurality of actuators in communication with the controller, each actuator configured to actuate a function associated with the working arm; wherein the first electronic joystick comprises four axes of movement selected from an x-axis i.e. side to side or lateral translational movement of the joystick, a y-axis i.e. a forward and backward translational movement of the joystick, a z-axis i.e. up and down movement of the joystick, a twist axis i.e. rotational movement of the joystick, and a first tilt axis, i.e. pivoting of the joystick about a forwards-backwards tilt and a second tilt axis i.e. pivoting of the joystick about a side-to-side tilt, the first electronic joystick configured to transmit electronic signals to the controller in response to being displaced along an axis from a neutral position; wherein the controller is configured to receive the electronic signals from the first electronic joystick, and to transmit an electrical signal to one or more of the plurality of actuators to actuate said actuators; and wherein the joystick assembly is configured such that the controller actuates a different actuator for controlling a different function associated with the working arm, dependent upon the axis of displacement of the first electronic joystick; characterised in that: displacement of the first electronic joystick about the twist axis controls slewing of the body about a vertical axis with respect to the drive arrangement. a body; a working arm attached to the body;
