I did my 50 hour service recently and used just about all 10 gallons of travelers that I bought. Recently I noticed that I don’t see any fluid in the sight glass even though it was over the red dot at the time of service. The other day I got a stiff pedal issue, both F and R, that was remedied by letting the tractor rest a while. I also noticed that the dust around my PTO looks wet, like a possible leak. I have no drips, no leaks, no obvious loss of fluid. If I park it rear downward on a hill I can see fluid. This morning I started the tractor on level ground with the bucket and the 3 pt all the way down and engaged the pto, tractor standing still, no fluid in the indicator. Thoughts? Fill it up with the bucket and 3pt extended, clean the pto area and monitor the sight glass to see if I have a leak?
