From Agricultural Tractor to Nissan Sedan

[DrJB]

I came across this real implementation of a 'quad-track' on a passenger vehicle. The closest set Lego has released is the 42038 Arctic Truck.

Those track elements have been known in the agricultural industry for some time.

Then, I also stumbled upon a rather impressive 'Sherp' Russian-made vehicle. I must confess that, with the tall grass in the Sherp video, I initially thought those were toy-sized (small) vehicles.

So, which of those have you already built, or plan to replicate in Lego?

Well,recently got a 42037 so now have four big balloon tires.Will try my hand at Sherp although I only have m-motors

Then I found this. The perfect candidate for those new 'light green' panels

I put quad tracks on my 8110 Unimog 3 years ago.

The Sherp reminds me of a skid loader with oversized tires.

EDIT: found a pic of real Unimog with tracks.

I got selected for one of top 100 winners back in 2013 with my MOD of 9398, I actually got more votes than winning model, but I shouldnt have removed wheels

Not exactly a quad track, but it uses a similar concept for the rear axles.

Anybody can buy them for their vehicle - they're just CRAZY expensive. If you want highway capable, they're about $10,000 EACH.

Those tracks are best used on snow and possibly dirt. On highway, they wear rather quickly and the treads are very costly to replace. Plus, I'm not sure you're allowed to drive those tracks on highways ... as I'm not sure one can go fast enough. The main reason they're used on agricultural machines is to cause very little compaction of the dirt underneath. Otherwise, compacted dirt does not grow seeds very well.

I actually made a quad-trac (same as the pic) for TC9, however, I had problems with the pics and video, so I wasn't able to enter it. Will probably have it posted soon...

Remember this one. The Ken Block version.

Yeah but you got the votes because of the wheels... it makes it awesome

Very nice, and I like the color scheme too. Those tracks put a lot of friction (and parasitic load) on the drive-train. I wonder if those vehicles are standard or modified.

Here is the video of the Subaru of Ken Block.

He also converted a ford F150 with those tracks.
