Yes, I agree, the scratches should not be there, even on a tractor.
Document everything (lots of detailed pictures) and tell them beforehand that you want it back in same condition.
And I understand your frustration with having a major repair on a pretty much new machine. Not sure about the legal situation in your location, but as far as I know in Germany for example you would be entitled to a new tractor or your money back or a repair, at your discretion. You do not have to put up with a major repair on a like new vehicle.
