Abstract
A forwardly-foldable agricultural implement includes a center frame supported by wheels and extending generally transverse to the direction of travel, and a pair of wing sections. Each wing section has an intermediate portion pivotally connected to the center frame by a foldable frame and being supported by a wheel. The foldable frame includes a pair of elongated wing support members having one end connected to the center frame and another end connected to the respective wing section. The foldable frame also includes a pair of hitch arms with one end connected to a two-direction pivot knuckle on a three-point tractor hitch and another end pivotally connected to the respective wing section and its wing support member. This structure provides a method of changing a foldable implement between a wide, field operating configuration and a narrower, road transport configuration without the necessity of a telescopic tongue member.
