I always wanted one, with the backhoe and front-loader attachment. I saw a video of one set up for snow removal. It had a 'snow-blower' that, threw the snow. The auger part was so powerful that it could suck up a puddle of water that was in front of it. To power the the snow-blower it had, I believe was a 12 liter, turbo-diesel engine in the back. It was used to clear the road that went up to Mt. Washington, NH.
Single stage. Wow. This thing is throwing rocks all over the place. At the end, you can actually see a stream of rocks in front of it. This is why dual stages are better for clearing streets. Rocks stay with the snow.
