Did you take the wheel off ? I had a flat on a mower and when I pulled the wheel off I did not see the key for the axal and wheel fall out as it was on the bottom of the shaft. This let the axal rotate inside the wheel and I could not move. There may be a disconnect for the wheels like my John deere has.
