Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

A person could also put on a simulation video.  Of how to damage a gear box and how to put excessive load on all of the blower components.  By by using to fast a forward speed for the
snow conditions.  Or by plunging into an EOD pile that has chunks of frozen snow and ice.
The impeller kit does one thing.  It improves the efficiency of the impeller.  It creates a smaller gap between the blades and the housing.  So that more of the snow that is in front of the blade is
expelled out the chute on the blades first pass by the chute opening.  Can that put more load on the engine and belt than the way it came from the factory, yes.  But would that load be any greater than than trying to blow 12" of wet snow in third gear instead of 2nd or first gear?  No I don't believe it would.  I guess my point is that with or without an impeller kit a person can damage blower components by using it incorrectly.  And you see people, or hear people doing it all the time.  As I said there is a small learning curve when using a blower with a kit installed.
A person can easily shorten the life of blower components by using it incorrectly. 

The gear box issue.
Putting an excessive load on the impeller has no effect on the gear box.
The impeller and gear box spin off the same shaft.  So when the impeller slows down due to a load so does the gear box.  You can't blow a gear box because of a heavy load on the impeller.
I would go so far as to say that if you have the correct OEM shear pins installed and the augers are free on the shaft.  You can't blow a gear box period.  All the gear box does is spin the augers
which moves the snow horizontally.  That is not a tough task for a screw auger.  What happens to often is that people get the idea that a snowblower is half snow plow and half snowblower.
Anytime you feed the blower housing more snow than is has the capacity to process.  Your putting an excessive load on it.  Just listen to the engine. 
Blowing deep wet snow is like cutting long wet grass.
