Did you see the scrapers that Farmers use on skid loaders, or any loader? They push and pull, they use tractor tires for the edges, way cool stuff. several co make them but I have the brochure in front of me from horstwelding.com. You can't tell me that the rubber free stall scraper with back drag is not cool. Plus when you back drag you can see what you are doing. Toys, toys, toys
By the way The whole reason I found these was for the same reason, 350 townhouse. Boy was I glad when I did NOT take it, the people were RUDE and well you know how the general public acts like, I dodged A Bullet on that one. I really felt sorry for the other poor guys who had to put up with Attitude problems of Snowed In townhouses!
