A family friend passed a few years ago and his widow is slowly starting to sell some of his stuff. This is how I was lucky enough to get my 30 diesel. She knows I'm a tractor nut. When I bought the 30, I casually asked about the 570 diesel. She said she wasn't ready to sell that yet. Fast forward 2 years, now she wants to sell it to me but we don't know what a fair value is. It looks very nice. New tires all the way around, new paint and decals. Very sharp tractor. The issue is there are some mechanical issues. I'm quite sure the injection pump needs gone through. It's leaked all the fuel from the tank into the oil. The other major issue is she said the last time her husband drove it, it lost all oil pressure. Said he shut it down as soon as he noticed and it hasn't ran since (about 4-5 years). She thought he said it needed an oil pump but nobody knows for sure. I really want this thing but don't want to over pay, but don't want to insult her either. She hasn't come up with a price either. It is a wide front without 3pt, but like I said very nice looking. Where would I start value wise?
