Abstract
A forwardly-folding, tractor-drawn agricultural implement featuring a rear center frame and a pair of wing sections that may selectively occupy operating positions in which they are horizontally and transversely alined with each other but alined in that manner forwardly of the center, rear section. This rear section carries no agricultural tools and serves basically as a rear rolling support for the implement in both its operating position and in a transport position in which the wing sections are folded forwardly along opposite sides of a central telescopic tongue or hitch by means of which the rear section is connected to and supported on a tractor. When the implement is in its transport or folded position, the overall length of the machine may be shortened to bring the rear support wheels closer to the tractor.
