Abstract
A suspension for a cab base on the frame of a swather tractor includes four dampened springs at the four corners with three links each pivoted on one end of the frame and the other end on the base. The links include two parallel links in the fore and aft direction parallel to the mechanical speed control link arm and one side to side link which constrain movement of the base against fore and aft movement and side to side movement parallel to the mechanical steering control link arm. This arrangement restricts movement of the base while allowing roll and pitch movements of the cab structure with the links arranged such that steering and ground speed are substantially unaffected when the cab moves on the suspension.
