Go to the registry and ask them what type of license plates your tractor might qualify for. A strange thing happened when I was living in MA. The police stopped a fellow that was plowing a shopping center parking lot and gave him a ticket for not having license plates on the machine. He told the judge that he was on private property and he believed that he didn't need them. The machine was trailered to the site and taken away the same way. The judge informed him that even though it was private property, that since the public was invited into the parking lot to go to the stores, that the same laws applied as if it were a public road. Guilty, and pay the fine. Based on what that judge said, I have come to the conclusion that all private land is public land, unless it is posted with no trespassing signs, and the police can enter upon it without a search warrant. I might be wrong, but this is my own assessment of how it works.

Folks think I am making this stuff up or that I have gone paranoid. Folks also thought I was crazy when I wrote that I needed a CDL medical exam certificate and something called a "hoister's license" to legally use my Mahindra tractor on my own property. Entire process took me more than 3 months, $125.00 in various fees, passing a written exam and waiting for the wheels of government to turn before I had the license in hand and could legally drive my own tractor on my own property.
