Bicycle wheel axles are /not/ indestructible.
But anyway, the Mountain Tamer[tm] Quad
or Triple might be right up your alley.

Just for laffs I Googled on: pedal-powered machinery

Here's the first hit I got:
http://www.velomobiling.com/BicycleMachines

Scroll down to see a pic of something like what you're
interested in.

For plowing snow, I wonder if something designed like
a grader, with a highly articulable blade (rotation and
elevation) positioned mid-vehicle would be more viable?
Such a config would allow you to ballast the front end,
if need be.

The above site also has a link to some sort of
pedal-powered washing machine; I think I'll follow
up on that one.

I haven't looked at any of the other hits yet.

cheers,
Tom
