1. A driveline arrangement for propelling a working machine, the driveline arrangement comprising:
a first driveline comprising a first electric machine and a first transmission arrangement, the first driveline being configured to propel a first pair of wheels at a speed range between zero speed and a maximum speed limit of the working machine;
a second driveline comprising a second electric machine and a second transmission arrangement, the second driveline being configured to propel a second pair of wheels at a speed range between zero speed and a predetermined threshold speed limit of the working machine, wherein the predetermined threshold speed limit is lower than the maximum speed limit; and
a control unit connected to the first and second drivelines, the control unit comprising control circuitry configured to control the second driveline to assume a disengaged state in which the second driveline is disconnected from propelling the second pair of wheels when a speed of the working machine exceeds the predetermined threshold speed limit.
