The one we used the ice came in 4ft square tote and was dumped into a hopper on the machine. I see this small one will use blocks and it even shaves the ice for use. It did a great job of cleaning up the old car body and leaves no rust behind. Two years ago we used a truck mounted one to take the painted runway numbers up at the airbase here. we had a limited time to do it and it worked well. No damage to the concrete.
