Screw-Powered ATV

Screw-Powered ATV

Russian all terrain vehicle using screws instead of tracks to cross tough terrain.  I don't think I have seen this before.  Pretty cool.

Weren't a lot of tractors like that back in the day?  Don't fall off.  Don't put your hand in there.

Our farming fore fathers were made of stouter stuff. Well, the ones that survived anyway.
If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or your arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that you were our countrymen.

Colin Furze built his own.

I may have seen a more annoying video some where in the distant past but, if so, I don't remember when or where. Between his talking like a 45 RPM record played at 78 RPM, his constant screaming, and the intrusive background music -- I barely made it beyond the halfway mark before I had to shut it off. It's a really nice bit of garage engineering, but his presentation just ruins it.

The Soviets had one also.

The M29 Weasel prototype was a Fordson Snow Devil, it eventually had treads.

FTFY.  His presentation seems to be pretty effective over all.

And WLJ:  Wouldn't the same thing happen with regular tracks?

And Hawmoon:  Agreed. I've noticed in watching some of our gunship attack videos there's a tendency to use heavy rhythmic contemporary loud music, too.  Gits yer dander up, I guess.

At least with reg tracks there's the hope you'll land on the tracks and can then roll off and failing rolling off I suppose, not knowing tractors better, that with your foot off the petal the tracks will quickly stop hopefully before dumping you in front of the track.
With screws, I guess it may depend on which side you fall off to, the screw is going to immediately start chewing you up like a meat grinder with you caught between the screw and the body of the tractor.

I've never been on a tractor with a gas pedal. I set the throttle lever to the rpm I need and it stays there until I change it.
Sometimes we carry more weight then we owe.

Like I said I don't know tractors all that well. Why that and not a petal? Maybe hard to maintain the petal in the same position and thus a constant speed while going over bumps and such?

Why not a kill switch wristband, or switch in the seat or some other method of shutting down the screws unless you're in the seat?

I did ask about a dead man's switch in my first post but in 1920s would something like that be considered?

You need certain rpm's to run some equipment. For pto speed.

And it would get kinda busy with a clutch and three brake pedals at my feet already.

Okay, now I'm curious about the three brake pedals.
I'm thinking main tractor brake, equipment brake maybe, and ?

One brake pedal works on both tires the other two are called steering brakes. If the front wheels are off the ground you hit the brake on the side you want to turn.

Interesting, I didn't know that. Sort of like brake steering on a tank as I understand it but I never drove a tank either

How are they arranged?
Is it
Both, L, R

L then clutch on one side both then R on the other.

All the tractors I've been on (not all that many, really) had two brake pedals on the right side; you could mash them individually or together.  The clutch is on the left side. Some had a link to tie the 2 brakes together to make one big pedal, then unlink it if you need to brake-steel to get out of a ditch or something.  I've never really steered with the brakes but have used them to get unstuck when just one wheel is spinning in the mud.

Also most tractors have a governor that is actually running the throttle.  You set the lever to the desired RPM, and the governor adjusts to varying engine loads to hold that RPM (For PTO stuff mostly.  Hydraulics especially).  That setup isn't super conducive to pedal control when you want consistent output speed.
