Snow Blower Prep: Local Deadlines by City
Service your snow blower about three weeks before the first plowable snow — a date that varies by city in the table below. Fresh, stabilized fuel, clean oil, a good spark plug, and spare shear pins keep the machine running and keep you out of the repair-shop line after the first storm. Our snow dates come from NOAA normals; the prep steps paraphrase consumer testers and makers like Toro and Ariens.

Fuel is the number-one no-start cause
Untreated gasoline can start to break down in about 30 days, gumming the carburetor over the off-season. Drain summer-old fuel, refill with fresh gas, and add stabilizer, or run the tank dry at season's end. Ethanol-blend fuel is especially hard on small engines.
A fouled spark plug and old, cold-thickened oil are the next two suspects. A fresh plug and an oil change are cheap insurance against a machine that will not start when you need it most.
Shear pins, tires, and a test start
Shear pins break on purpose to protect the auger gearbox when you hit buried ice or a newspaper. Keep two to four correct spares. Set tire pressure to the printed spec so the machine tracks straight, and do a full test start well before the first storm so any repair happens on your schedule, not the storm's.
How we set the prep deadline
We estimate the first plowable snow from monthly snowfall normals and set the prep deadline three weeks earlier, so the machine is ready before the first storm and before shop backlogs build. Because first-snow timing is an estimate, we label it as such on every page.
