Craftsman 24” two stage 4-cycle 5.5 horsepower Tecumseh engine. Its push-button electric start helps to eliminate pull-starting a cold engine along with the need to mix oil and gas. Its self-propelled drive features 5 forward and a 2 reverse speeds which is designed to provide control and versatility in winter conditions. It had services last season with new oil changed new spark plug and new belt. We bought new snowblower and did not use it this season. Started right up today.
