Any suggestions on where to start troubleshooting my BX MMM 60". Dang thing is stuck in Pos 4 and I cannot turn the adjuster knob. Deck goes up and down o.k. just can't turn the knob. Thanks

How many hours on the mower? Could the adjustment knob be rusted. It is a pita to get to but sounds like the cam bolt is stuck.

About 150 hrs. I was in the process of adjusting it ,went to 4 and that's where she sits. Has been working good. Any idea where that cam bolt is.

It is the height adjustment knob. The bottom of the bolt is bolted to the frame. Do you have a parts manual for the tractor? It will show you how the height adjustment is set up.

I assume the deck is at it's highest point when you try to adjust the height?
