I apologize for asking another MMM question but the owner's manual didn't cover this; can the MMM adjuster knob be turned both directions? It seems as though my adjuster knob can be turned either way until I reach the 00 mark then it wants to only go one direction, I can continued to turn through it but if I try to go back the way I came it won't let me and I don't want to force too hard for fear of damaging it. I still cannot understand how the tractor was shipped to me with the adjuster set on 2.0 if the MMM was raised as high as it could go, and I believe it was. I suppose it is possible that someone at the shipping company was monkeying around and turned the knob. Oh well. Thanks for any help or input!!
