Old pull type forage choppers and equipment for ametures on the cheap? in General Chat Posted November 18, 2021 I sold a 555 IH cutter on a consignment auction for $300. They were the last in the cut and throw line that included the 50, 55, and 550. As far as parts are concerned I don’t think anything is available any more. Knives and shear bars are high wear items and if it was never replaced, the spout and cutting chamber floor sheet can get pretty thin. One that has been outside will probably have rusted gathering chains and sprockets. if you could find one that was used little and stored inside, they are reliable and do a good job. Good luck.
