Have a pair of stalk stompers that originally came from Shoup manufacturing. Will work on JD corn head, or should also work on a row crop head. Bought them last year, but before putting them on, found a set of duals for the combine, so no longer need them. They are brand new still in the box. Paid over $230 each, so this is basically half price for the pair. Could probably make them work in other applications as well.
