"Anyone can drive it, but can you make ice?"

-- Jack Kirrane, Zamboni Driver and 1960 Captain of the US Olympic gold medal hockey team

Resurfacing the ice consists of a few basic steps: the machine scrapes the ice with a sharp blade, creates new ice with 192 gallons of ice making water, fills in ruts with 72 gallons of recycled wash water, and smoothes the surface with a towel. Operation of the resurfacer is complicated because many external factors affect the condition of the ice.
The Zamboni driver is constantly concerned with where he is on the rink, adjusting the flow of water and the height of the blade. Humidity, drafts, and body heat all affect the ice. In an outdoor rink, the ice is at the mercy of the elements.
It is also crucial to maintain and create an even level of ice, ideally 3/4"-1 1/2" high. Resurfacing prevents chipping and other "bad" ice that makes the hockey puck bounce and ice skaters unhappy.
