Guy that had it before me told me that he used it in 4WD fairly often, to keep things working. Sort of like using your parking brake, so it won't seize up, and fail you on an inspection...
I kicked it into 4WD, and drove it up a fairly steep hill in my yard. Got all 4 tires to spin, so I know it works!
Now I gotta go patch the lawn...
