Anyone have experience with your instrument panel glass turning a cloudy white color on top half and some of it looks like a dripping shapes after running at PTO RPMs for quite a while--for example brush hogging a field.

I have a JD 2740

Condensation inside the instrument. See it all the time. It usually clears up after it warms up.

I have a 2520, and I get some condensation during cool down after about an hour of mowing. It clears up fairly quick. Obviously, some moisture is getting in there, but I cant figure out how. It's not ideal, but I'm not too worried about it.

My JD 4300 does that when I have been bush hogging for several hours. It really doesn't look like condensation and it is usually hot dry days when I am out mowing. The first time it happened, it looked like the plastic had gotten too hot and was permanently damaged so I was surprised when it was cleared up the next day. It doesn't cause any real problem and it does always clear up.

I don't know about the 2x20s or the 2x40s, but the JD4x00s have a glass instrument
cover that is varnished on the inside. The varnish can go bad, as well as the rubber
gasket. On my last 4300, I took the cluster apart and used a razorblade scraper to
remove the varnish. Now, it looks like new.

A good rubber gasket should keep the humidity out.

My 4200 had the same problem.I took the cluster apart,removed the lens,cleaned it and the gasket with rubbing alcohol and reinstalled.no more problems

My 4300 has the same issue. Glass will cloud up and then clear as it cools. Never have taken the cluster apart, figuring I'd probably screw something up...

Also had the same problem on a 2000 yr JD4700. The dealer was "helpful" and more than happy to sell me a replacement instrument module that "would eliminate the problem". And of course the new one clouded up just like the original. So, like everyone else, I just grinned and beared it, like most loyal JD'ers.

Try cleaning the inside lens surface with Rain-X anti-fog or Kleer VU. As mentioned above, it's condensation and the anti-fog should solve your problem.
