Abstract
Abstract A loader or other vehicle provided with three pairs of wheels located as closely to each other as is practical while allowing a small space between the peripheral surfaces of adjacent wheels; the axles of the three pairs of wheels extending transversely of the vehicle, with the center axle located in a horizontal plane lower than the horizontal planes of the front and rear axles, providing four wheel traction at all times automatically utilizing either the combination of two front and two center wheels or the combination of two rear and two center wheels depending on whether the vehicle load is greater forwardly or rearwardly of the center axle.
