to be honest it was a deep ditch and trying to steer and climb I was afriad Id smoke birfields or worse. so winched away.
I 3-way lock it before I get into really bad mud and then I keep up my RPMs. If my rig slows down, I turn the wheel back and forth. It usually keeps me from needing my winch. With that said, there are times when the mud is so soft and deep that you immediately sink to the axles. In those instances, you aren't going anywhere without your winch.
