Very cool and the thing is they are single stage augers!
It's not so much the type (single or two stage) it's the auger size and speed (larger diameter = greater tip speed for a given RPM), how much power is behind it, and how well the design is implemented.
This is what I replaced my 10 HP 28" track drive two stage with:
(sorry for the bad pic, it's dark in the back corner of the garage)
Hydraulic drive & lift, 21 HP, 900 RPM, 48" auger -- makes snow go away fast. Case/Ingersoll has been making this basically unchanged since the late 60's or early 70's. Mine is a 1983 and you can buy practically the same one new today.
