This experiment was performed with the similar methods reported in the paper No. 3 and 4.
In this test, the wheel had one lug that was put on with 4 different angle was used, and it was advanced by the pulling force and the torque force, Then, one test of them was the unpowered rolling, and the other was the powered advance.
Then the deformations of the soil by each wheel were photographed. From that results, it was found that the moving of the soil, the appearances of the sliding shear planes and the directions of the principal stress were not effected by the angle of lug, but they were varied by the locuses of thier lug planes in the soil.
