On what kind of surface would a square wheel function the same as a round wheel?

Having just read the 10-tree orchard comments, wherein "nobody said" the rows had to be parallel, i will note that for this problem nobody said that the wheels had to actually roll. A complete lack of function satisfies the stated requirements. So the solution (or A solution) is, a surface deep in mud to a depth of N, where N is at least, oh, 1.5 times the radius of the wheel.
