what did you end up buying? I have heavy gumbo and had a jd 960 annd it would not go thru evan heavy stalks evan after the winter breakdown. i bought last fall a dmi tigermate 2 , an older blue one. there seem to be a lot of them in my area and work well. the jd 980 are good ones also but hard to find a used one. the 980 still had the jund bushings on the top of the shank though. well see this spring, i do not work standing stalks but everyone says you can with the 980 and the tigermate 2. the newer deeres are prob better yet but very pricey. good luck i evan had trouble going thru bean stubble in the spring with the 960.
