I agree, it looks like it would work well for snow. Expecially with the chain and the ability to "float" over some un-even ground.
But I wonder what it would do if the blade were spun around backwards and pushed into a pile of snow. On a truck mounted blade, the blade will ride up the snow bank. I wonder if this one is designed to do that or if it would bend something with that chain setup.
PS, How much does one of them cost??
