If I ever got my hands on a versitile Bi-directional tractor The very firts thing i wanted to build for it would be a grader. In my mind it looks realy easy. I would take the whole front half off an old road grader, right back to the cab. I would weld this too a frame that would attach to the 3pth on the cab end of the bi-directional tractor. See where im going with this???? on the grader, I would hook up the front wheels to hyrdrolics to steer them, in away i would have crab streering. The rest of the blade would be run off the tractor as well, I would control lift, angle, pitch and sideshift from the tractor cab. The newer 9030 Ford bi-direct tractors seem to have a lot of hydrlic capabilities, but don't realy know, " i don't have one yet" :-( But the theory will work for your freind too. Why get an other grader when all the grader he needs he's got. HE can do the same thing. Cut the grader in half, and attach the front half to a frame to some how bolt or pin up to the front of his Ih tractor. double steering might be a little tough to figuer out, but if the tractor steering was roped in a straight position and steered the combo from the grader front by the tractors spool valve it would work. Your only backing up and driving foward in just about straight lines. realy the only thing your freind might need is a pto pump, tank, hoses and valves to power all those hydrolics on the grader, if the tractor at best had for spools you might beable to runn the whole show from the tractor. Am i making sense, I think it would be much easier to grade facing forward rather than trying to build a windrow while looking over your shoulder. ask me if any thing seems confusing, hey the idea's great in theory!!!
