Hi. I just bought a little kubota L2600f tractor with 300 hrs on it. Not sure what fluids have been changed in it so I decided just to change everything front to back. I do not have a manual. I'm wondering if someone could tell me what type of transmission/hydralic fluid should go in it. I did some reading and some said gear oil and others said hydralic fluid. And also it has a fill hole in back and fill hole in middle by gear shift with a sight glass window on side. Does both holes fill same thing or is each for different reservoir? All recommendations and input on this tractor much appreciated.
