ABSTRACT:
A folding implement frame includes a central tongue frame and a pair of elongated boom frames mounted to the tongue frame for movement about first pivot axes. The boom frames are movable about the first pivot axes between towing positions extending behind the tongue frame in a narrow roadway travel configurations, and outward operative positions extending substantially laterally of the tongue frame. Rigid boom pull bars have outward ends pivotably mounted to the boom frames on second pivots and inward ends mounted to strut linkages. The strut linkages are mounted to the tongue frame for pivotal motion thereon about third pivot axes, and to the boom pull bars for pivotal motion thereon. The strut linkages also include provisions for enabling adjustment of the length of the strut linkage to enable pivotal motion of the boom pull bars and boom frames between the operative and towing positions. The strut linkages remain connected to the boom pull bars and tongue frame during such motion. Selectively operated castor wheel assemblies and operating controls are provided to enable selective motion of the boom frames to and from the towing and operative positions without requiring manual manipulation thereof.
