Single Stage, Two Stage

Single stage A single stage has a collection auger and throws snow directly from the auger blade to a chute.  Single stages run at high rpm so the augers spin much faster than two stage augers.  They have to in order to get the speed of the snow up to go out of the chute.  

Single stages generally do not have wheel drive.  They are pulled along by their rubber augers.  That works well on smooth surfaces and they will pull themselves up mild smooth slops.  They can move over frozen ground and grass and it's a bit rough at times but still work fine.  For most storms cutting a path with a single stage would be much easier than with a much bigger two stage.  For most higher snows >5 inches a single stage will struggle and require a lot of pushing.    

Single stages have a 10 to 16 inch bucket intake housing so have trouble with drifts, EOD, or big snowfalls.  For the smaller snows they are fun to use and keep the hours of use off the bigger machine if you have two.  For walkways, decks, roofs and other specific jobs they are great.  Although small in size and horse power a good 3hp can throw 20 to 25 feet and in some cases clear faster than a two stage. 

For very wet snow like slush they do pretty good compared to a two stage which generally have lots of trouble with very wet snow.  The rpm rate of the two stage augers does not collect wet snow well.

Two stage A two stage has augers which push snow into an impeller which throws the snow out of the chute.  Most two stage snowblower augers turn at 120 rpm.  Their impellers turn at 1200 rpm.  Almost all two stages have driven wheels.
Two snowblowers Some people have two snowblowers.  A larger main snowblower and a lighter backup.  Some get a main two stage and a smaller single stage for backup, slush, and light snows.  
Two cycle Must mix gas and oil together.  No oil reservoir so no oil changes.  High revving, small, but powerful engine.  Simple construction.
Four cycle Has oil reservoir.  No mixing oil and gas, requires oil changes.  Quieter than a two stroke.
