Abstract
A backhoe boom is pivotally connected to a swing frame for vertical movement relative thereto. A power extendable and retractable linkage is connected between the swing frame and the boom and includes a hydraulic actuator having one end pivotally connected to the boom and having its other end pivotally connected to respective first ends of a pair of links having respective second ends respectively pivotally connected to the boom and to the swing frame. The links make it possible for the actuator to position the boom in a raised transport position wherein a connection of an outer end of the boom with a dipperstick is located rearwardly of a transverse vertical plane extending through a connection of an inner end of the boom with the swing frame.
