I own a Ford 1920 four wheel drive and recently bought a !620 tractor with no motor for the loader to put on my 1920. The guy I bought it from claimed it was a 1920 and I figured I would keep it for parts, but when I got out there it was a 1620. I was able to get it for a very reasonable price and the loader worked out great, but now I end up with a four wheel drive hydrostat 1620 in seemingly great condition that I would love to find a motor for. The tractor also has a 72" belly mower on it and a cab. Does anyone know where I can find an engine? If not, what should I price it for and where should I advertise it? Might sell mower separate? What is it worth? Thanks for any info!
