Kubota HST Leak at Split Pin Drain/ Clutch Housing

[evanjohnson]

I have a Kubota L4610HST with approx. 350 hours.
It worked fine the last time I used it but when I went into the garage it looked like it peed hydraulic fluid.
It looks like it's coming from the split drain plug on the clutch housing.
Anyone have any ideas?
Thanks,
Evan

If it is hydraulic oil for sure it means the input shaft seal to the tranny has woofed its cookies. This would require a split and new seal installed.

My L5030 weeps out this hole, only a drip every so often. I don't know if it is from the tranny or engine side though.
