Sprayed it yesterday with wd40 several times .
Was still stuck this morning.
Sprayed it with PB Rust Buster.
Taped it with a hammer a few times.
Clamped a small pair of vise grips on the shaft not the plastic knob.
Gave a fairly firm tug on the vice grips and it broke free.
Lubed it up good with white grease amd it turns free and easy now.
Think I will clean it and lube it at each engine oil change.

Glad to hear you got everything working the way its suppose to.

I do not have a BX, but I do have a B7610 with the same 3 pt lowering speed adjustment knob. I think your idea to check it and at least lube it a little on a regular basis is a good one.

*Thanks.
I'm going to do the same with the mower height setting knob too.
I've had them freeze up on me also.

So I was working on my BX2230 today trying to get to the hydraulic system fan, and unscrewed the 3 point lowering speed knob... fluid came out :( I quickly realized that was a mistake! I screwed it back in immediately but I am worried it is broken now. What can I do to fix it?

I suspect its fine. It sounds like you lost the retainer ring stop of some sort. On mine the valve goes only so far. Have you tested to see if if still lowers and control the speed of lowering the 3 pt arms ?

I'm a little late to this thread, but what the heck....
I new at all this stuff and digging for knowledge. THIS subject is actually something I can address with "expertise".

My new to me B20 came with a lowering adjuster that was non turning.
I tried my maximum manual twist, which though not as vicious as it used to be, is still pretty reasonable. No joy.

Knowing from reading the manual that it was supposed to turn, and the knob being metal, not plastic, I first put some penetrating oil on it. After a while I searched out my rounded jaw channel-locks grabbed the knob and .... nothing but scraped up knob and a bit of twisting of the rod. Scary stuff brute twisting a strange knob.

To help eliminate scarring up the knob some more, I tightened up the pliers
and took a stronger grip. I cranked in both directions, being mindful of not
making the shaft torque much. Ever so slowly I got it to tighten a smidge.
I then worked it back and forth, and little by little the shaft freed up!

The system now works as advertised.

The moral of the story seems to be that one should keep this thing lubed up and exercised on a regular basis, perhaps while doing the "10 hour" joint greasing routine.

And, perhaps this is a system that is underutilized because of misunderstanding or lack of knowledge as to it's benefits.

OK old hands, what's the poop on best practices with the 3-point lowering speed adjustments.

Regards,
Dennis

Once you`ve got it moving, smear some grease around the shaft where it goes into the casing. And stop washing the tractor, water gets around the shaft and rusts it solid.

My 2 cents

Or leave it sitting in the rain etc. One thing nice about the ROPS is that it makes a good tent support if you bungee a good sized tarp over your rust prone iron if leaving it out.
