Zamboni

A Zamboni is a truck-like vehicle or smaller device used to clean and smooth the surface of an ice rink. The first ice resurfacer was developed by Frank Zamboni in 1949 in the city of Paramount, California. A large, very sharp blade, similar to those used in industrial paper cutters, shaves the surface off the ice, and an auger in front of the blade sweeps the accumulating shavings to the center of the conditioner. Many ice resurfacers are fitted with a board brush, The brush sweeps into the conditioner the bits of loose ice that accumulate along the kick plates below the dasher boards of the rink.
