Abstract
A four-wheel drive tractor with front-wheel steering on the front axle and rear-wheel articulated steering to provide maximum traction, stability, and maneuverability. The front axle pivots on a pivot longitudinal with the vehicle body and the front wheels pivot relative to the axle to steer the front end of the vehicle. The articulated vehicle bearings are positioned near the rear axle to provide a long front frame supporting portion for the operator station of the vehicle and to improve stability of the vehicle when the vehicle is articulated.
