Cost of ownership on a snowblower? My last one was a cheap $500 MTD, and lasted 17 years. Total repairs? 1 cable, and one belt, less than $25. $525/17 is $31 a year. I need to clear my driveway 3 to 5 times a week on average. The snowplows around here would charge $35 for my 150' driveway each time, and I'd still need to clear my sidewalks and porch myself. It's less than $1 doing it yourself, that includes gas and "cost of ownership". Takes about 20 minutes.
My current snowblower was $700, but being an Ariens with a Subaru engine, I'm expecting a longer life than the old one. My neighbors Ariens is from 1971, and shows no signs of stopping yet.
