There are a couple of 50" rear mount snow blowers for sale locally. In low range, reverse is 2mph according to tractordata. Seems about right; it's nearly as fast as third. I think I'll be quite underpowered. If I was going front mount, I think I could go slow enough to make it work. I don't have live PTO either, so if I'm not thinking ahead, I'll be trying to lift the 3 point while the tractor is already bogging. If it was front mount, I could shift down low enough to make it work. I think I'll pass, but wondering if anyone has done anything similar and made it work. Making it work in my case also involves busting the berm left by the plow.
