I have a 48 foot shipping container sitting on 6X6 beams. It weights 12,000 pounds. My biggest tractor is a 350 IH with two sets of wheel weights and loaded tires, but the AT is out. Will my tractor pull this? I want to move it 100 feet straight move forward across sod. The container has openings at each bottom corner to hook to nice and low and I would be sliding it on the beams as I went, not the ground. The container also has two rails under it which it is sitting on and what it would be sliding on. All of this brings up weight class question to me. When you say your in a weight class of 10,000 pounds is that the tractors weight? if that is the tractors weight how much can you pull? A 10,000 pound tractor pulls 10,000 pounds? Is their a ratio?
