How Long Do Snow Blowers Last?
In This Guide
Buyers often ask how long do snow blowers last, and the good news is that these are simple, durable machines. A quality snow blower that gets basic care commonly lasts 15 to 25 years, far longer than most people expect, because the engine is lightly loaded and only runs a few weeks a year. What actually ends most snow blowers is not the engine at all, it is neglect between seasons. Here is what determines the lifespan and how to stretch it.
Typical Lifespan by Care Level
| Care level | Expected life |
|---|---|
| Neglected, fuel left in over summer | About 10 years |
| Average, occasional service | 12 to 18 years |
| Well maintained, fuel managed | 15 to 25 years |
Because a snow blower only runs a handful of weeks each winter, engine hours accumulate slowly, so the machine usually outlives the owner's patience with an old design rather than failing outright.
What Actually Kills a Snow Blower
The number one killer is stale fuel. Gas left in the tank over summer turns to varnish and gums the carburetor, and repeated over years it corrodes the fuel system. The second is wet storage, which rusts the auger housing and hardware.
Mechanical wear does happen, augers, bearings, belts, and the friction disc on the drive, but these are all replaceable parts, not the end of the machine.
Simple Steps That Double the Life
At the end of winter, either drain the fuel or add stabilizer and run it through.
Change the oil once a season, before you store it.
Store it dry, off a damp floor if you can.
Replace shear pins, belts, and the spark plug as they wear, not after they fail.
Grease the auger and check the gearbox oil per the manual.
When an Old Machine Is Worth Keeping
If the engine starts and runs and the auger housing is solid, an old snow blower is almost always worth repairing over replacing. Carburetors, belts, and shear pins are cheap, and a 15 year old machine with a clean bill of health can easily do another decade.
When to Let It Go
Replace when the frame or auger housing is cracked or badly rusted, the engine has lost compression and will not hold a tune, or the gearbox is worn out. At that point the repair cost approaches a new machine and buying makes sense.
A seized engine from running low on oil is often terminal on an inexpensive machine, since a replacement engine can cost as much as a used blower.
