a first prime mover;
a transmission powered by the first prime mover rotating a drive shaft and wheels of the vehicle;
a first PTO coupled to the first prime mover;
a second PTO coupled to the transmission;
a second prime mover configured to provide power to the first prime mover through at least one of the first and the second PTOs or receive power from the first prime mover, wherein the first prime mover rotates using power from the second prime mover without using fuel; and
a third prime mover coupled to at least one of the first and second PTOs to provide power to assist in propelling the vehicle without using fuel, wherein the second prime mover and the third prime mover receive power from a rechargeable energy source, wherein the first prime mover reduces fuel consumption in response to an increase revolution per minute of the first prime mover caused by a power increase in at least one of the second or the third prime mover.
