Boss Snow Plow with 09 Ranger 500 H.O.

[Arrowthrower]

I have a Ranger 500 H.O. with a Boss Snow plow system. I have experienced nothing but trouble with this system. We got 2 inch's of snow the first time and it worked perfect. After that 5" and it would die and not start for 5-10 minutes. It also lost a huge amount of power. I took it to the dealer(still under warranty) and they replaced the belt and said the engine is going bad. I got it back with another 4" of snow and same thing, and this time the 4wd starts to act up. So i take the Ranger back today and the dealer discovers that front axle is broken and he is definitely going to replace the engine. He sold me on upgrading to a H.D. 800. I haven't written the check yet, i wanted to see if anyone else has had the same problem and what recommendation are. I remove snow commercially and was hoping the Rangers would be a good fit. Maybe not!!
