I'm looking for parts for my 646 case/Ingersoll garden tractor, looking for everything and anything related to 600 series, will look at ALL rusted out or not! Let me know if you have anything, snowplow or blower? I have a running 1977-446 case that I would trade towards 600 series tractor project also I have a Rototiller for possible (trades Only)? This is my retirement project. thanks
