I have an original JD Model N, 1960's vintage I presume, still has the original wood and tires and you haven't seen tire cracks like this sucker has but still hold air on a bi-annual basis without having to add air. PTO runs the slinger and a lever controls the ground driven floor scraper that determines the flow rate when dispensing. I think I paid about $700 for it and only needed a piece of ladder chain (TSC supplied) and straightening out of a rt angle steel scraper bar to put it back in working order. Might have a look for something of the sort.
