It's pressurized fluid from a plugged vent.

Transmission oil is 6" below the shifter boot. How does the oil get all the way up to the boot? Vent isn't plugged. Put air in the oil fill hole and it comes out the vent on top. Still get a little oil in the boot though.

Here is Hoye's diagram. You might be missing the o-ring that secures the bottom edge of the boot.

I would just add a ziptie like Gary suggested and forget it.

If someone were paying me to solve the problem then I would replace all the soft parts there - boot, ball, o-ring. Also the rollpin that secures the shift lever to the plastic ball. Total maybe $20 in parts.

On my Yanmar that 75 cent rollpin is the only part that broke since I bought the tractor in 2003.

I can see how the O-ring would act the same as a zip tie. Just needs a little pressure to keep the boot sealed in the groove. I've had mine apart and still can't see exactly how the oil gets up, past and through the ball but it does occasionally. Never very much but just enough to wet the top of the shifter housing. Maybe when everything is new it's tighter.

Well, the oil was slightly overfilled. And it only started coming out after a couple of hours of working the tractor. checked the vent, don't see any stoppage. Put a zip tie around, cleaned up, and will find out next week if this fixed it. Thanks everyone. And just discovered hoye parts, good find. Moved alot of dirt and rock with it, and am very happy w/ the little machine.
