Bill T., sometimes when I get *just a little snow* I'll just use the snowthrower as a blade and when I get to the end of my driveway I turn on the snowthrower and throw the accumulated snow. I'm curious, you stated: "Since the thrower already has the lift and spring-trip mechanisms...." what snowthrower do you have that has a "spring-trip" mechanism???
I know that the BB36, CW36 and CC36/CC42 snowthrowers have springs on the front but I do believe that they are a type of lift assist.....
