Agricultural tractor

An agricultural vehicle, especially a tractor, includes a chassis separately supporting the front wheels. The front wheels are controlled by a steering cylinder arranged on the chassis and driven by output shafts (28) of a differential gear (17) having a differential gear box (16). At least the front part of the chassis with the suspension of the front wheels includes two frame parts (6, 7) extending in longitudinal direction and arranged in a laterally spaced relationship to each other. The differential gear box (16) is designed and arranged to fit and to be detachably mountable between the frame parts (6, 7).
