Dave, I've noticed that no one has given you an answer to your question, ARE THERE ANY REASONABLE TRACKING GPS DEVICES OUT THERE IN THE MARKET WHICH CAN BE EMBEDDED IN OUR TRACTORS OR EQUIPMENT??????
I don't know of any, but would like to know is there is a low cost GPS tracking system. I've seen on TV where a very expensive air compressor was stolen and it had GPS on it. Police was able to track it.
