Anyone else have trouble with mower height adjustment?

I just took the tiller off my BX. When I put it on, I lifted the belly mower and set the height knob to TOP. In the past, when I took off the tiller, I could turn the know back to 3. Now the knob is stuck tight in the TOP position. Any suggestions how to get it working again?

Never mind. I thought about it, cranked up the rpms, pulled on the lift lever and at the same time rotated the knob which moved freely.Just had to take the pressure off.
