ABSTRACT:
An agricultural implement includes a main frame and tool-carrying outer sections foldable between transversely extending operational and fore-and-aft extending transport positions. The folding mechanism transversely separates the inner ends of the outer sections as it simultaneously rotates the sections rearwardly into transport position. Tools supported on adjacent ends of the sections are thus separated to eliminate interference therebetween during transport.
