ABSTRACT:
A tractor which has three or four wheels on each side, two of the wheels on each side being mounted on a bogie which includes a wheel carrier. The bogie is pivotable relative to the rest of the vehicle about a horizontal transverse axle which connects it to the frame of the tractor. The foremost and rearmost wheels are steerable and driveable. In one embodiment, the intermediate wheels are also steerable and driveable. Lifting devices are provided to extend from both the forward and the rear of the tractor. An engine together with a transmission and differential gear is disposed between the foremost and the rearmost wheel axles. A cab has a driver's seat and steering wheel with a control console which may be rotated together whereby it selectively faces forwardly or to the rear. A cab in two embodiments is disposed forwardly and is centrally located in one embodiment. Two gear trains supported in a parallel relationship in the frame of the tractor are respectively connected to the differential's output shafts. The gear train may be connected to drive the wheels via shafts with universal joints and an outboard pinion which meshes with a gear mounted on each wheel disc. The construction allows all of the ground-engaging wheels to contact uneven ground whereby adequate support for the vehicle on soft ground is provided.
