790 compact tractor 1,600 hrs vibration

It might be my imagination but the engine seems to vibrate harder at idle than it used to. I've owned this since new in 1999. The engine starts quickly and easily, seems to have full power and no sign of a miss or weak cylinder - it just has a stronger vibration than what I think it used to have. Above 1,000 RPM it smooths out.

Thanks, I use Stanadyne Performance Formula in my diesel engines and have for years. The fuel for this 790 comes from the same off road fuel tank that I run a Kubota ZD326 from and that idles smoother than the 790.
