Abstract: An agricultural vehicle and method of controlling the same are provided, the vehicle having a motive power unit providing a driving torque to at least one driven wheel and having at least one tire or track frictionally coupled with the periphery of the driven wheel. A vehicle operating parameter is controlled in dependence on the driving torque and a slippage characteristic relating the respective driving torque at which the frictional coupling between driven wheel and tire or track begins to slip for a range of vehicle operating parameter values. The operating parameter is suitably a tire pressure or track tension, and the control may involve reducing driving torque or increasing pressure/tension to prevent slipping.

Abstract: A drive train arrangement for a tracked or two-wheel drive utility vehicle including a transmission and differential axle. The transmission has on a first side a rotatably driven input adapted to couple to the output of a motive power unit of the vehicle, and on a second side opposed to the first, an output shaft. The differential axle unit, which may be a steering differential, has an input coupled with the transmission unit output shaft and a pair of output shafts operationally coupled with the input via a plurality of planetary gear sets. The transmission unit output shaft extends outwardly of the unit also on the first side, and has a vehicle brake assembly mounted to the output shaft on the first side.
