A prime mover system includes a first prime mover, a first drive shaft, a differential, a power take-off (PTO) drive shaft, a second drive shaft, a transmission, a first accessory, and an output shaft. The first drive shaft is operatively coupled to the first prime mover. The differential is coupled to the first drive shaft. The PTO drive shaft is coupled to the differential. The second drive shaft is coupled to the differential. The transmission is coupled to the second drive shaft. The first accessory is operatively coupled to the PTO drive shaft. The output shaft is coupled to the transmission. The transmission is configured to transfer rotation of the second drive shaft to the output shaft. Rotation of the PTO drive shaft is independent of rotation of the output shaft.
