Z-Mich, For the price diff of $100 go for the 84". Your 50HP will easily handle it. I run an 84" Lorenz double auger on my 36HP tractor. I bought it used off CL late last winter but got to use it on our last big storm. It worked very well. I'm in the snow belt just S.E. of Lake Ontario and have the blower on back and PA plow on the front for our winters.
