Increased traction on the high drive wheel of a tractor, self propelled implement or other vehicle while tilted laterally because of sloping terrain is provided by structure which permits shifting of the weight of the operator toward the high side of the vehicle. The operator's seat is held against tilting by a rigid attachment to its mount, but the mount itself is swingable about an axis disposed well below the seat and extending fore and aft of the vehicle. During tilting of the frame to which the seat mount is swingably attached, the operator's weight may be maintained in alignment with and spaced vertically above the central longitudinal axis of the vehicle by operator control of a power device which effects swinging of the seat mount. The steering wheel, instrument panel, dashboard and footrests may also be swung in one direction as a unit with the seat mount about the same single axis common thereto as the vehicle frame, its engine and its front and rear axles tilt laterally as a unit in the opposite direction.
