What is the difference between a single stage and two stage engine in a snow blower or lawn mower?

Answer 1

There is a big difference in a single stage and two stage snow blower. A single stage blower uses a single impeller to do both auging the snow and discharging the snow out the shoot. Major disadvantage in heavier snow belt areas or if the snow is wet a single stage does not perform as well as a 2 stage which uses a larger motor generally a 4 stroke over a 2 stroke (gas and oil mix ) uses two augers one to pull in the snow and another to discharge the snow out the shoot . Major advantage in wet or heavy snow conditions also 2 stage blowers are normally self propelled. As for a lawn mower there is really no two stage type you can get one that bags side discharges or mulches as a single unit as for a type of two stage mower these are generally on tractors with a power flow assist for bagging generally on decks of 52" or more. As far as size and price go a two stage blower is usually larger and takes up more storage space and a single stage is mor compact less storage area required. Price depends on size and thrills you want. If you look at numbers on a two stage the first indicates the motor size the second is the auger width (824) 8hp 24" auger this is the same for a single stage. Hope your ? was answered.

Answer 3

In a snow blower that is a single stage the auger is doing both tasks of bringing in the snow and blowing it out the chute. A two stage has a separate impeller that blows the snow out of the chute.

For a lawnmower, I believe a two stage variety has an impeller to move the grass and clippings to the capture bag instead of relying just on the force of the mower blade.

A two stage snow blower has large gathering tines in front (the first stage) and a smaller, faster exhaust tine inside (second stage) to throw the snow out the chute. A single stage is just a toy if you ever have more than 2" of wet snow.

Answer 5

I think the question you are truly asking is what is the difference between a 2-cycle engine (found in most single stage snow blowers, and chainsaws), and a 4 cycle engine (found in most two stage snow blowers, and lawnmowers).

A 2 cycle engines spark plug fires every time the piston goes up. They produce high RPMs, and require oil mixed with gas, as they do not have a separate oil reservoir for lubricating the engine. They tend to be used in applications where high speed and lightweight are required.

A 4 cycle engine is what you find in your car. The spark plug fires every other time the piston comes up. They produce more power, and are heavier. The gas and the oil are separate and do not mix. These tend to be used where power is required and the engine size is not a big issue.

I hope this answers your question.

I own a 2 stage snow blower w/12 hp motor, and it does everthing I could ever want. Get 1 with a handle crank for throwing direction!! I had 2 with auto control urn up in 3 years, no more of that!! Dress warm&good luck

Answer 7

a single stage snow blower has one ogger that moves the snow up a 2 stage has one to lift snow off drive and one to give it a boost to throw it much farther if you are doing more than a sidewalk or single drive or heavy snow you will want a 2 stage
