A 755 wasn't really designed for plowing. He would do well to pull a single 12" or 14" with it. I would recommend he consult a John Deere dealer for advice. There are three things that come to mind: (1) hydrostatics take a beating when you use it for ground-engaging activities such as plowing, (2) lack of adjustable wheel tread may be a problem for furrowing; meaning your wheels won't ride in the last furrow as they should, and (3) low ground clearance may cause you to get hung up. I may just be overcautious, because I have broken equipment using it for other than it was intended. However, were it mine, I wouldn't plow with it. Hope this helps.
