A working machine includes a prime mover for supplying torque to the driving wheels of the working machine, and a transmission line arranged between the prime mover and the driving wheels for transmitting torque from the prime mover to the driving wheels. The transmission line includes a gearbox arranged between the prime mover and the wheels, and the working machine further includes at least one hydraulic machine in a hydraulic system for moving an implement arranged on the working machine and/or steering the working machine, and an electric machine for driving or braking the driving wheels and/or for driving or braking the at least one hydraulic machine. The electric machine is arranged in parallel with the prime mover with respect to the transmission line and is mechanically connected to the transmission line between the prime mover and the gearbox. The gearbox is a continuously variable transmission having a variator unit, and the gearbox has an operation mode where the rotation speed of the output shaft of the gearbox is zero or close to zero independently of the rotation speed of the input shaft of the gearbox at the same time as torque can be transmitted from the input shaft to the output shaft.
