Choosing a Snow Blower - Two Stage Vs. Single
Snow Blower Weight and Storage:
Because two stage snow blowers typically have a bigger motor, more parts, and wider clearance, they are mostly heavier than single stage snow throwers. In lighter snowfall areas this makes them much easier to maneuver and use. With a smaller clearance and fewer parts, single stage snow blowers typically require much less room to store.
Clearance Width:
While single stage snow blowers typically have a clearance width of 21 inches or less, two stage snow throwers regularly come in 24, 30, or even 45 inches for prosumer models. A larger width cuts the chore time down considerably in large removal areas. As shown in this graph from Lowes.com areas with snow accumulation of 12 inches at a time and 40 feet should consider a 24 inch clearance while those who have a total of 60 feet or more of accumulation should probably consider a 28" clearing width two stage. In areas with heavy snowfall in excess of 16", you may want to consider a snow thrower with a 30 inch clearance.
What type and how much snow fall do you receive?
I've seen a lot of reviews that make the amount of snowfall you receive pretty cut and dry as far as what you should purchase. While it is true that in general, areas with lighter snow fall of 2-6 inches should probably go with a single stage thrower, you should also take into consideration what type of snow you get. Wetter snow and slush, for example, is easier to discharge through a two stage thrower.
Also, if you're the type of person that goes out of town and lets snow accumulate, then even if you don't get more than 6 inches at a time it may still be wise to consider a two stage model.
What size is your driveway and what type of terrain are you pushing through?
Another reason to consider a two stage snow blower would be if you have a large driveway where additional width would be necessary. While the general consensus is 40 feet long you may also want to consider the size of a third car pad or other cement areas you need to cover like walkways.
One of the reasons I personally got a two stage is because we live in a corner lot that has a walkway on the front and sides. The wider clearance allows me to make 2 passes instead of 3 and because my two stage has self-propelled wheels it's much easier when I have to go uphill.
Also consider the type of driveway you have. Two stage snow blowers are typically better for gravel driveways because they don't typically have to touch as near to the ground.
