The vehicle comprises a self-bearing chassis, a plurality of running bearing wheels fixed in a rotating manner on horizontal axles at each longitudinal side of the chassis, a drive wheel fixed in a rotating manner on a horizontal axle at one of the ends of each longitudinal side of the chassis and, a track tightening wheel fixed to a horizontal axle at the other end of each longitudinal side of the chassis downstream of the last bearing wheel. At least one of the rear bearing wheels is supported by the chassis with its axle movable in the vertical plane containing it, there being provided linkages for moving the wheel from a lowered position, in which part of the track running thereon is in contact with a longer portion of the underlying terrain, to a position wherein part of the track is raised from the terrain.
