since grip is the main problem here, not power, laying a brick *onto* the machines could provide much better outcomes. I suspect the tracks would be affected more than the tyres, since they distribute their weight over a much larger surface area, decreasing grip per area

and limited slip differentials.

For the tank treds I think that if you put the black 2x1 connectors pieces on the treds, It might have increased the grip because the connectors would have been digging into the carpet instead of the technic bars just slipping (Kind of like a cars tires on ice, the tires starts to lose grip and well slip) theoretically the connectors would prevent that problem, as if you were to put chain over the tires on the car I used as a example. If you put the connectors on to the technic bars and then supported those bars on the side that would most likely need to be supported it would improve the tanks grip as it already has the torque to pull more of those bricks. Just an idea that had probably been in some others people's minds that I thought I wanted to share because I felt like typing out a problem that could be fixed, even though you've probably already thought of the idea I wrote about.

Seeing those doubled-up tires makes me want to go drive a farm tractor.

I didn't realize how more wheels = more traction. I thought the traction would just be more distributed, not amplified. I guess the added weight of the wheels and support is what adds more traction. If the same weight was added without the additional wheels, my guess is that it would have the same traction.

Tractors and other farm machines do this I always thought it was to distribute the weight over a larger area so if you hit a slick spot it doesn't start slipping and sink you to the diffs. There's also the option for instead of two standard tire and rim to have a single fat tire. Some silage trucks run fat tires instead of duals, call them "floatation tires".

I like the content and you spent lots of time putting this together. That is much appreciated., Your frictional coefficients between the tire contact and track contact are not equivalent. Also, the tire vehicle creates a moment of traction that is not spread equally across, especially, the rear axle. The outside tires create a V structure which creates a non-linear friction curve for the tires closer to the apex of such V, which is modified by the hitch attachment point. Try an experiment where you move the hitch point under the axle to the center, or just forward, of the rear axle. Make sure the non-static linkage (tow rope) has a trunnion or vector block under the rear axle.

The corrugations on that tote lid are setting up more drag for the tires and tracks to overcome. Maybe try a test with the weights on a smooth-bottomed drag sled?

With a little weight on the front of the 4x4 it would have done much better. Especially once you added the 1st and 2nd set of extra tires the front tires were not doing much due to weight transfer. If you had sat 1 brick on the front I think it would have pulled quite a bit more or twisted an axle trying.

Whenever the car/tank is pulling over the bricks to the cone and takes around 7-10 seconds Pls do like 2x or 1.5x and if u wish to , rather then machine sounds , add light music Just vehicle sound when crucial moment like axle break and stuff If u add these (totally up to u) the viewing experience would be lifted too much 😳😅😈🤞🏻🤣🔥

You solved my question about FS22. It turns out that the dual tires are more powerful than the tracks.

It isn’t the addition of tires and tracks that is making them pull more, it is the addition of weight. The term is ballast, and simply means to weight the unit to put the power to the ground. Look up ballasting agricultural tractors for more information. Simply put you need to have the proper total unit weight and front to back weight ratio for the most efficient power transfer, which was off for the tires unit as you could actually see it shift in the last couple pulls. You did not power out in this video, you always spun out, so keep adding weight to the machines to find the max pull. You also should have the weights the same for both machines to accurately compare the systems directly. But in a nutshell you are showing with blocks, what we do in the Agriculture world!
