For many users, buying a snow blower is a significant investment, and you will want to ensure that it will last as long as possible. For most snow blowers, you can expect an average lifespan of 5-7 years, but some can last much longer if of a more high-quality brand. Taking good care of your snow blower and storing it properly, out of the snow and damp, will help extend its lifespan. Often, battery-operated snow blowers may just need a new battery if it starts to wear down, rather than buying an entirely new snow blower.
