1. A method comprising:
when a requested power or a requested torque is greater than a respective threshold, operating a driveline in a first mode, the first mode comprising engaging a first electric motor and a second electric motor to an input of a transmission; and
when the requested power or the requested torque is less than the respective threshold, operating the driveline in a second mode, the second mode comprising engaging the first electric motor to the input of the transmission and engaging the second electric motor to an input of a power take-off (PTO);
wherein the first electric motor and the second electric motor are connected to a coupling device, and the coupling device is connected to the input of the PTO and the input of the transmission, and
wherein the coupling device comprises:
a first reduction ratio between the first electric motor and the transmission, and a second reduction ratio between the second electric motor and the transmission; and
the transmission comprises a first gear ratio and a second gear ratio.
