Most gas snowblowers feature either a single-stage or two-stage mechanism, depending on how the snowblower collects, processes, and expels snow. Most single-stage gas-powered snowblowers have intakes that range from 22 to 24 inches wide, while two-stage snowblowers can have intakes that are up to 32 inches wide. Single-stage gas snowblowers can launch snow up to 40 feet, while two-stage snowblowers have a snow-throwing range of 50 feet or more.
