Help needed on RD7 value

[thebilly]

My friends recently showed up with an RD7. It was sitting in a pasture for who knows how long. Anyway, the drug it some and got it started and it crawled up on the trailer. I understand it is in pretty good working order all things considered. The goal is to sell it but have no idea as to it's value. Can
anyone give us an idea or who to contact. I know this is really vague but we
just don't know where to go. Info on these old dozers is kinda hard to find for a novice. Thank you...Billy

:Welcome1: Glad to have you here. I know we have a couple of Caterpillar guys around, and they will probably pop in soon with an answer. Just wanted to welcome you to the forum.

sorry didn't see this earlier any attachments on the cat? do you know if its 9G or 5E series? i've got a 9G i paid scrap price for had to pull it out of the bush and winch it on. don't see to many on sales anywhere. just to give you an idea of value mine has cargo winch on rear both engines turn over i haven't run it yet. i was offered $3500 for it from a iron jockey so he likely new of a buyer at a healthy profit to him.
