  2. That is cool! Too bad it didn't catch on. I see a great potential in that type of drive.

  4. He's holding a steering wheel but I wonder how that would actuate the actual controlls. I'm guessing it turns be speeding up one screw and slowing the other like a bulldozer does with its treads but bulldozers don't have steering wheels. The mechanism that would use a steering wheel to control proportional hydraulic valves would be an interesting one.

  5. I was trying to think how I could come up with something funny do describe this contraption, but I finally said "screw it" and gave up.

  6. That’s Henry himself. There was some use by the US postal service in the upper Midwest somewhere I believe.

  9. looks like the steering wheel is attached to something that swivels the bars the screws are attached to, hen he goes over the jump you see the bar shift position to change the screws from being equal to one being just ahead of the other

  10. I suspect the steering wheel is somehow attached to the individual brakes to accomplish steering.

  11. If the screws are hollow then it looks like enough buoyancy to qualify as an Amphib.

  12. If its a tractor base, then maybe it just uses the existing rear wheel brakes and differential to direct or withhold power to one screw or the other. Cool idea though.
