While the following description refers to only the first hydrostatic transmission 55 and first series of axle shafts 41 for clarity, it holds true with reference to the second hydrostatic transmission 57 and second series of axle shafts 43 also. Such a movement would be cuased by the tensioning forces exerted on the chain 131 by the driving forces supplied by the prime mover 53 to the various sprocket wheels of the drive system. The wheels are essentially overgrown roller blade wheels. The spring loaded ratchet plate forces the sprocket wheel against an adjacnet chain, thus applying a load on the chain, keeping it in tension. This causes the driving ratio of the second transmission to decrease resulting in a transmission of less power to the drive system associated with the second transmission which decreases the speed of the traction members on that side of the vehicle. 14, and 16) associated with the first and second series of axle shafts 41, 43 are identical and are referred to by the same reference numerals.
