1. A prime mover system comprising:
a first prime mover;
a first prime mover drive shaft coupled to the first prime mover;
a second prime mover;
a second prime mover drive shaft coupled to the second prime mover;
a first differential coupled to the first prime mover drive shaft and the second prime mover drive shaft between the first prime mover drive shaft and the second prime mover drive shaft;
a first drive shaft coupled to the first differential;
a second differential coupled to the first drive shaft;
a power take-off (PTO) drive shaft coupled to the second differential;
a second drive shaft coupled to the second differential;
a transmission coupled to the second drive shaft;
