I ran across this last night at Mario’s. The lovely lady acting as hostess told me that it is called a wovel, wheelbarrow shovel. She said that it was invented by a young man who worked at Mario’s several years ago and he holds the patent on it. He has upgraded the device to have three wheels, she told me.
I wish I knew enough about mechanical advantage to calculate how much this device would ease the burden of snow removal. The handle can be adjusted to several different positions, as seen in this photo:
It would appear that this would be an ideal device for older folks to move snow with less effort. The wovel site has a lot of details and photos.
