On the way to my property I ran across these for sale.
The JD M was supposedly used not to long ago. But, needed a new battery. I took a few pictures of it if someone is interested. I thought the price was high. 4K. But, I'm not too knowledgeable on dozers let alone antique ones. He also had a Case "Terratrac". He and his friend were rebuilding it. But, his friend died and he just wants to sell it. Don't know what state or disarray it's in. I only got pictures of the Hydraulic winch and blade. The rest, he said was at his house in the shop. If interested send a message.
These are located in East Texas.
