A 3 position can lock the wheels so that they drag, let them freewheel, and have normal 4wd. Some older digs were 2 position that did not have freewheel and were used primarily for tighter turning. Freewheel is good for some climbing when the axle is trying to drive under an obstacle, and for running down steep slopes.
