when you purchased it did you get a "Certificate of Origin"? This is the document that is presented for the first time a title is issued. I got one for my boat trailer, but CT doesn't issue titles for boat trailers, so I still have it. I asked about one when I purchased my Kubota, but the dealer said that they didn't issue them for tractors. I found this strange, because it is considered a "motor vehicle" when used on a public road and as such must have a registration plate issued and insurance. I know that in MA any vehicle that is used in a parking lot of a shopping center must be registered because they consider it "public". I learned that when I was doing some plowing in a shopping center parking lot and the other crew was piling snow with the loader. The loader didn't have registration plates and the driver was ticketed for operation of a motor vehicle without a registration. When he went to court, the judge said that was the law and it must be registered even though it was on private property because the public was free to use the property.... i.e. shopping.
