A seven footer on that tractor "may"be a bit too much.Depends how
much you get at a time.I had a six ft.on a L3130 sub-frame mounted
and that was all it wanted in deep snow.I had R1's rear loaded.
Converting a front plow is by far the cheapest route. And if you already have front hydraulics and a ssaa....you don't have much work to do to adapt one.
