Looking at a Farmall that is for sale ,it looks like a 100 has the 11 bar grill and same style front rims as 100, but does not have hydralics or any name plates the serial tag is sprayed over so I would have to scrape it to read. It does look alot like an A but some how appears to be just a tad smaller in size and less beefier than a A :? So with out scraping the tag is thaere a way to ID this tractor?
