Thank you to everyone for their thoughtful replies. I've come to the
conclusion that, as much fun as it might be to acquire an adult-sized
pedal car, its just not ideal for the job.

Mostly, pedal cars seem to be a bit wider than i'm wanting; i'm trying
to stay at about an 18" wide track. Mostly, i want to stay gage
compatible with the currently extant plowing tech in service. As i
wrote originally: a pedal powered bulldozer (but not necessarily
tracked!)

This leads me into waters i fear to navigate: building something my
self. Atomic Zombie freakbike stuff. Welding! terrors!

I'm envisioning some sort of horror created from several gas-pipe
Huffys. I want at to have at least 2 drive wheels, maybe 3 or 4. I'm
thinking 20" tires or smaller. I would probably significantly ballast
the contraption, likely with snow, improve drive wheel traction. In
general, i'm not fond of a single front wheel solution. I would prefer
a two-wheel front end which will give a better mount for the plow.

I'd be interested in any pointers anyone might have to a torque
_increasing_ derailleur lashup. I'm intending to build something that
will have significantly more torque multiplication than your average
MTB granny gear. If i understand the concept correctly, i'm thinking
of being able to shift down to on the order of 4 gear inches or so.

Such a thing seems pretty simple on paper, but ... i don't know
anything, really.

The Huffy vivisecton i can manage w/o too much trouble, but I'd be very
grateful if anyone has pointers on the high-torque derailleur stuff.
