O.K, I have turned up an old 2-14 Case eagle claw hitch plow. The eagle hitch part is easily gotten around with newer CAT 1 pins installed for an updated hitch system. It was originally pulled by an early '50's SC Case tractor with the equivalent same amount of H.P as my 790.
A 2-14 plow behind a 790.... I got my thoughts on pulling such a plow with a 27 H.P 790, would like to know yours
