I have zero knowledge of allis chalmers tractors other than d21's and 220fwa look really tough. That being said, I rented a farm this spring that an old farmers niece/nephew just inherited. I spotted an allis in the barn, but didn't want to push the boundaries. They made it very clear that nothing was for sale. Just today, I walked by the barn and the door was open. It's a 7060. A few minutes later I'm chatting with the nephew and it sounds like they might start to sell some equipment now. This interests me. Could use a 150hp tractor. Would mostly chisel plow and haul wagons. Are these good solid tractors? It hasn't moved in 5-6 years. What problems did they have if any? Not sure of hours yet. Should be up there in the next couple of days and will ask if I can look it over better. What kind of value do these have? Thanks
