When to service the snow blower
Service or buy a snow blower in September, before the October rush and the first storm. The right week depends on when snow season tends to arrive at your place.
Yearly reminder, four weeks before snow season.
Why service early
Snow blowers fail most often on the first storm of the year, when old fuel has gummed the carburetor and repair shops are booked solid. Servicing four weeks before snow season gives time for parts, for the work, and for a test run.
The date above is computed from the 30-year mean monthly temperature at your nearest station: snow season is defined as the first month from September onward with a mean temperature at or below 2 C.

Questions, answered plainly
When should I service my snow blower?
Service or buy a snow blower about four weeks before snow season tends to arrive at your place. That is usually September in the north and September to early October in southern Canada. The first storm always creates a shop rush; the goal is to be ready before it.
What happens if I wait until the first snowfall?
Repair shops and parts shelves get busy, and a machine that sat with old fuel may not start when you need it. Stale fuel and a seized carburetor are the most common reasons a snow blower fails on the first snowy morning.
Do I need to service a new snow blower every year?
Yes. At minimum, change the oil, inspect the drive belt and auger shear pins, and run fresh fuel treated with stabilizer. Even a new machine needs the same checks if it sat unused for months.
