ABSTRACT:
Two tool-carrying beams extending laterally in opposite directions from the tongue of the frame may be swung fore-and-aft between lateral working positions and folded back transport positions. A collapsible link between the tongue and each beam, respectively, may be held partially collapsed against the tongue to maintain its beam in the operating position, or the link may be released for partial extension to permit the beam to swing back into its transport position. Although the innermost tools of the two beams are disposed in close proximity of one another when the beams are in their widespread working positions, the vertical pivots for the beams are so disposed that the beams can swing through arcs exceeding ninety degrees without causing said innermost tools to strike one another.
