Engine displacement is approximately 242 cubic inches. The 6640 was available with various transmission options, including a standard 8x2 synchroshift, an 8x8 mechanical shuttle, or a Dual Power transmission offering 16 forward and 8 reverse speeds. PTO horsepower is rated at approximately 65-70 HP, with options for both 540 RPM and 1000 RPM PTO speeds, depending on the configuration.
