| 摘要 | A vehicle, especially adapted for agricultural use, and having two engines in coaxial alignment in a frame and adapted for coupling together. Each engine drives the primary part of a torque transmitting arrangement, electrical or hydraulic, and secondary parts of the torque transmitting arrangement are connected to drive the vehicle wheels. Controls are provided to control the distribution of power from the primary parts to the secondary parts to determine the wheel, or wheels, to receive the power and the speed of rotation of the wheels. At both ends of the vehicle there are provided means for connection of implements to the vehicle and including lift type hitches and power take-off shafts. | ||||||
