Yup, we've got 4 of 'em in our City organization. We use them with a snowblower mounted for clearing snow off of bridge sidewalks, around buildings and walking paths...just about anywhere it's too tight to get a pick-up with a plow into. Each one also has a salt spreader mounted on the back end. We also use them for pushing leaves in the gutters in the fall. They have very large U shaped "blades" mounted, and they push a whole block in one sweep to an intersection where a endloader picks them up and dumps into a dumptruck.
They're really handy pieces of equipment, but I'd think they're a little pricey for the average tractor owner type.
