How The Zamboni Works

SHAVING
A blade (A) scrapes the surface of the ice.

RENEWING
Clean hot water is spread on the ice by a towel (G) behind the conditioner.

COLLECTING
After a horizontal screw (B) gathers the shavings, a vertical screw (C) propels them into a snow tank (D).

WASHING
Water is fed from a wash-water tank (E) to a squeegeelike "conditioner" (F), which smooths the ice. Dirty water is vacuumed, filtered and returned to the tank.
