BX2200 MMM Height

[carlcroom]

My MMM seems to be slipping down. The adjustment screws on the rear mower links are in the topmost position and yet I have to mower height knob at the 4 inch position to mow. Any lower and I'm mowing dirt. I used to mow at 3 or 3ｽ.
What am I missing? Is there some other adjustment or stop that might have changed?
Thanks

My adjustment knob got stripped and I had to put a new one on it. Can you adjust it so your deck stays in the transport position? If you can, you will then just have to count clicks until you can get a new knob.

I later had to replace the whole adjustment mechanism when the retaining nut on the bottom of the cam came off and I lost the rod and cam.
