An apparatus for controlling the relative positioning of two hingedly connected implement portions movable between deployed or working and folded or stowed positions relative to one another includes a strut like component connected between the two implement portions and in the form of an hydraulic damper or shock absorber which is extensible and retractable in damped fashion. When the connecting component is fully extended or retracted, it serves as a strut for transmitting forces from one implement portion to the other to effect movement of said implement portions to or from their working and stowed positions. At other times, when not in a fully extended or retracted position, the connecting component serves as a damper dampingly resisting relative movements between the two implement portions to yielding absorb impacts and other dynamic loads imposed on one or the other of the boom portions.
