Yes, that guy is using his self propelled snow blower and standing on a snow sled to move him around. You're not supposed to do that but there are people around here who do that and more.What's that contraption? Is that the snow blower you mentioned before?
I have a self propelled snow blower like the one below. And this is the proper way to use a snow blower. I also have a smaller non self propelled one for less snow.
I only break out the big one when the snow is really heavy and/or deep. My small one gets used for light fluffy snow. Many times with a light snowfall I just use a shovel. It's really good exercise.
