But look at how many blocks of wood are on the ground at the same time dissipating the weight of all that iron over a much larger area than the very small footprint of tires which would make ruts and sink into the disturbed soil.
Think about seeing very large very heavy bulldozers on construction sites pushing dirt, sand, gravel, etc. around being propelled by tracked driving mechanisms.
P. S. I’m guessing used in flooded rice fields.
There resemble a sheep foot roller due to the gaps between the blocks, take notice of the second machine, there is no allowance for the wood blocks.
