Abstract: The drive train of the present invention is adapted for use with a vehicle having a frame supported on forward and rearward wheels, power means on the frame, and a drive shaft driven rotatably by the power means. The drive train comprises a differential housing having an input shaft and two output shafts adapted to rotate in response to rotation of the input shaft. On the end of each output shaft of the differential is a sprocket which is registered with a second sprocket which is drivingly connected to the wheels of the vehicle. The second sprocket is spaced from but adjacent to the first sprocket, and is coupled to the first sprocket by a chain sprocket coupling which is trained around both the first and second sprockets. The differential housing includes a bolt bracket which permits bolting of the housing to the vehicle frame.
