This thing looks like the bomb for plowing a mid size drive.

I can't figure out how the single track model steers.
Sure looks fun.

Looks like the kind of thing I'd expect to get invented in Northern Québec.

Tilting, pulling, pushing the handle to get different parts of the track digging differently

When does the gas powered version come out?

You mean diesel, right?

Sure, anything fossil fueled will do I was just kidding!

"What's your ride?"

"A giant chainsaw sled."

This is an old idea, traditionally combustion engine driven, that someone turned electric. Move along, nothing to see here. (have a look for Track-Packs and the Ruff (circa 1942). Russia had the Itlan and the Technomaster.)

Can you provide some URLs?
(Google is not great at looking for old stuff)

I always like seeing pics & diagrams of old-but-innovative tech.

Can I get an RC one so I can lay back in the sled and drink hot cocoa?

Sure. There are some in here:

We had similar units in Canada in the 60's (with , not quite as speedy as the electric jobby shown here) with I believe (not 100%) some of the early Kohler or perhaps OMC single cylinder gas engines. One could stand on a small foot board that was skidded along behind, steering with two large handles (like a roto tiller), and then behind that there was a sled with high enough walls that you could haul firewood, straw bales, sacks of whatever without them spilling out. They were geared rather high, so not a lot of speed but that's what was required to keep the torque up on these 2 strokes.

Hope this helps a bit.
