I am thinking about building a 4x4 140 with my grandpa. I have two extra 140 h3's sitting around and we are thinking it will make a cool toy. has anyone ever done this with 140's, what does the average articulated 4x4 garden tractor end up costing approximatley, is this pheasible or am i nuts to attempt this? We are also trying to decide which way to put them together, like others have done with 300 series machines or international 2+2 style.(The IH 2+2 ia a farm tractor). we both have mechanical/ welding/ fabricating experiance.
