I have received a JD model 670 4x4 compact tractor from my relative's estate but don't have any idea what it might be worth or what year it is. It only has 632 hrs and is very clean, has the big turf tires and runs great (don't believe it spent any time out of cover). I know the model number M00670A104116. Is there anyway to determine it's year and value? I don't really need it and want to sell it but not give it away. I am located in central VA.
