So clearly, the "therory of open mode vs. locked mode" is bull$hit. When all those chunks were "flowing" around in that carrier it was "open mode". Once they wadded up into a knot that was "locked mode". It's amazing we made it home on the rear end and didn't have to go FWD! We even yarded that last log the rest of the way out on that heavy-duty $hit.
Chevy runs deep, WAY deep!
