You kind of got the short end of the stick, but at the same time in reading between the lines it sounds like your tractor was a bit rough. I have no idea what you have for a machine, but not every old tractor is worth keeping. Its hard because like you once I had to trade in my old 1958 Ford 900 Wide Front End Diesel Powered tractor. Only 1500 were made, but it was in rough shape and I needed the money to make the down payment on a new one. Yes it was my Grandfather's tractor and it had many miles and many fond memories, but sometimes things just aren't worth keeping.
Also keep in mind that in rural areas, lawsuits sometimes cost far more than they are worth. I am not talking money here either.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
