Basically, if I hook the tractor to a wire rope and pull, what kind of force will I exert on the wire rope? I realize there are alot of assumptions to make, but I was really wondering if anyone had a rule of thumb for a traction coefficient for this size of tractor on soil. Say if the 3/8" wire rope had an expected strength of 12,000lb, and the tractor is say 8,000lb; it would take a "traction" coefficient of 1.5 before the wire rope would break (for now, let"s ignore momentum and jerking on the wire rope). I don"t think the mechanical power of the tractor itself is at issue here - it will spin out before powering out. I just want to know what force might be exerted on the wire rope. If it"s more than 12,000lb, then I just need to be prepared to duck.
