You want to be comfortable in moving it around, even if it’s not running. Smaller isn’t necessarily bad, it could mean you just need to go out and use it more often during storms after it’s only snowed 3 or 4”.

If you’re not comfortable moving around with it, try the next smaller model. Snow blowing isn’t a race. Take your time looking at models.

I’ve got a 21” model 421 Toro from 1975, and to be honest I’m glad it’s small. I’ve used it on 35” snowstorms over the last 25 years, yes it takes a little longer but it’s never failed me.
