The 944K starts with a 13.5L diesel engine bolted to a pump drive and two AC generators. An inverter box manages power, and four wheel motors provide traction. Brake resistors burn off excess energy as the machine slows down, but some energy is pushed back to the generators to run the hydraulics. Related
