what is the advantage or disadvantage of a 2 stroke engine vs a 4 stroke engine as it applies to snow blowers,

Answer 1

I don't know of any snowblowers with two stroke engines. The advantages of a two stroke would be less weight and no oil changes. The advantages of a four stroke engine would be more reliability, more weight. With a snowblower, more weight means better traction. Other advantages are quieter operation, more fuel efficiency, and power over a larger RPM range. I wouldn't even look at a two stroke snowblower.

Answer 2

I, too, have not seen a snowblower with a 2 stroke engine. Power would be one big concern. I don't think 2 strokes come in higher horsepower. I would not buy one that was less than 5 HP.

Answer 3

Most 2 strokes have the rubber paddle type auger and are usually not self propelled.They are great if you don't have a large driveway and the snow is not too wet/heavy.
4 stroke engines are found on most self-propelled blowers and generally are more heavy duty units.
