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.
