An ice resurfacing machine for small and medium-size indoor and outdoor ice skating rinks comprises a light towing vehicle, a resurfacing attachment, and a lifting and leveling assembly connecting them. To eliminate ruts in the ice, the machine removes only a thin layer of ice by scraping, fills the ruts with “snow” created by the scraping, skating, and precipitation, and adds water to fill the rut. The cold from the base ice and/or the atmosphere freezes the water and thus eliminates the rut. The machine may also be used to remove heavy snow or reduce the thickness of the ice.
