I only use this tractor on the disc mower and the baler, so I am out of luck on that.  What was your idea on how I am getting hyd. oil in the diff/trans?  How do I diagnose it?  Also, how do I adjust the pto so it will come to a complete stop when I shut it off?  It still turns slowly even with the lever all the way back.  If I shut the engine off and start it right back up it is then off, but it usually turns a half a turn or so when the engine starts then you here a click or a pop and it stops.  Do you adjust that on that valve on the back cover that the lever operates?  Or am I dealing with something else?  Sorry for so many questions.
