A couple of things:
The snow caster is filled by the forward motion of the implement carrier.
Friction and heat are created by the conveying of the snow by the cross
auger and the impeller in the case of a two stage unit creating resistance.
These crazy three stage units are a waste of money and I defy anyone to
explain away why they are better, THEY ARE NOT because of the inherent
inefficiency of the open cross auger design with the worm gear design.
Snow builds up in front of two stage snow casters simply because of the open auger
design(this does not occur with single stage snow casters-its in and out. IT pushes the
snow out in front of it at all times rather than meter a certain amount to the center of
the snow caster which is MOVING FORWARD.
A single or two stage snow caster will create a pressure gradient whether
it is full or not as air is being forced out of the chute, into the spout
and then out.
A single stage snow caster is more efficient as it removes the snow
ahead of it with one motion with higher torque delivered to the high
speed cross auger that conveys the snow to the center paddle where
it is ejected out of the chute and spout.
The open cross auger designed units are easier to build and cost less to build.
I am still waiting to see a two stage snow caster with a solid cross auger
like the old single stage units on old the cub cadets/simplicity tractors-post 1969
or a well built single stage front or rear mount.
The good snow blowers are single stage units with either a high speed cross auger
with ripping teeth in the single stage cross auger or the cross auger used for the
two stage units with Yamaha and BCS providing the best design in the home owner
market.
This method requires much more horsepower and torque but
The single stage four "scoop" single stage units with an ice and snow cutting propeller mounted in a wing plow cutting the snow into its smallest fraction making it easier to cast away.
