Do you really believe that the Ralph, the naked gardener actually meant that in all seriousness???? /forums/images/graemlins/confused.gif
On the serious side..... using a letter & number punch, mark the tractor in a place that only you know about with information that will have some meaning to only you. That way, if it is stolen, and the paper serial plate is pealed off, you can prove that it is your tractor if it is found. I don't believe that the tractor manufacturers mark the frames in any permanent way for identification. Do this on all of your equipment that uses removable serial plates. I know of a car that was stolen and the serial number plate was replaced with another. The owner was able to identify the car because of a "defect" when it was manufactured. It had different trim nameplates on each side. When he saw his car in a parking lot, he was able to prove it was his by this. Further investigation revealed the changed serial plate and he got his car back.
