Gas powered, single stage, 21". Steele brand. New blower at least $300. Still looks shiny, but the plastic casing has some damage from snow impact. Used it for less than 10 h total. Starts easily. Engine is perfect condition.
It is a single stage blower. Does not do a good job (unlike a self-propelled dual-stage slow blower costing $700). It cannot cope with thick snow well. I want to get rid of it from my garage. Priced for quick and easy sale. The almost new engine alone is worth more than $50. You can test it before buying. Don't expect a wonder machine for $50. Be realistic. I want an easy sale for such a low price.
