My 3 point adjustment knob, located under the seat, will not turn any more. It seems to be stuck in one position. It will not turn either way. Any ides?

This is on an L2500

Spray it up with "PB-Blaster" that should break it loose. That stuff work really well.

The way that I have done it is to soak with PB Blaster where it goes into the housing. Let it soak for a couple of days. Then use a pair of vice grips very gently on the shaft.

OK I'll bite on that one. What is PB Blaster? Some sort of penetrating oil?

It is really good stuff, napa sells it. I used it to bust a 4'' gate valve loose, I was impressed with its performance.

Yes, it is. I haven't bought WD-40 for a few years, because PB Blaster is that much better.
