WOW .. we don't have snow at all, all we have is desert, very high sand dunes. Imagine having that in the desert

Do you have to be in reverse to go forward?

Looks great in off the road level field conditions. But what about hilly terrain. It also appears it's not rated for highway use since only off the road was shown. How heavy are the track units and how practical is it to haul and set up in the field.

In other words: turn your vehicle in to a tank!

#2 No, look at the wheels at 0:30

I like how no one actually watched the video.

#2 you can clearly see the wheels going forward at 1:55 (and many other places)

and #3 1:55 they also show going up a hill, and at 2:29 they show it going (surprisingly fast) on a road.

The music says it all !

OK, now how do you get them off?

I know they are #5 & #6, it's quite obvious...I was just wondering how it works...must be some sort of cog system, like this:

I was wondering how efficient the system is at transferring power from the wheel to the tracks....neat system though !

#8....the reverse of getting them on I would think, unlatch and drive of !

#6 Unlike flatlanders, in western Pa we call that a bump, not a hill. I don't think driving on public highways with any device that limits your speed that slow is safe unless the roads are snow covered and everyone else is driving slow. What I didn't notice is the truck going at the top speed with the track on dry pavement and the driver jamming on the brakes.

Additionally, it appears they have attached the device to the trucks wheel lug nuts. What are the safety chains attached to the truck frame for?

Its a good idea for specific applications, but I could be wrong

#1 I can imagine it and the sand would destroy the mechanism. You could maybe have a few hours of fun before one of the tracks seized up. Better to use oversize balloon wheels like on a dune buggy in the desert. The value in having removable tracks is that you don't have snow year round so you can switch back to a regular truck. From watching the video I estimate mounting time for the tracks to be about 20 minutes. Decoupling could be done faster about 10 to 15.

#11 Why would you take the tracks on the highway for any more than a few slow miles if you can remove the tracks in about 10 minutes and put them in the bed of the truck? Of course it's a niche product for specific applications; it's called snow. If you have good plowed roads available to you then you don't need it.

And now make the same kind of "simple device to make it fly!

Very cool, but I'm guessing you probably burn through a ton of gas using these things. Nevertheless, still very cool idea.

Now that is one awesome invention for people up north. Only question is how much does it cost?

The only catch is the $20-25,000 price tag!
