You can change front ends pretty easily on those, the factory front end had weak spots . if your going to put a loader on it, and don't mind it not being factory setup I would put a 4430 front end on it. If I remember right there's only about 4 bolts holding the front end plate, just unbolt those and unhook the steering lines. Also a rear end out of 6620/7720 combine should fit and you can make it front wheel assist. There's all kinds of info on the conversions on you tube.
