ABSTRACT:
A tractor having a steerable axle that pivotally moves laterally in response to a corresponding steering action of the steerable wheels mounted on the steerable axle is disclosed wherein the front of the axle is pivotally supported by a four-bar linkage to control vertical movement of the chassis relative to the steerable axle during lateral relative movement between the chassis and the axle. The mechanism is composed of a spherical ball joint connecting the steerable axle to the chassis, a front carrier member pivotally connected to the chassis, and a pair of link members pivotally interconnecting the carrier member and the steerable axle. All pivot axes associated with the carrier member and the link members coincide at the spherical ball joint.
