Agent Orange: Friendly fire that keeps on burning.
I have a factory installed one on my MT Cat. It is a case drain and there is an oil filter in the line before it dumps back into the system. Although it looks like a standard Pioneer Female coupler, it's a bit smaller -- takes a special end. If that's the case on your tractor, now's the time to hunt up the special end.
