    I have a scag sthm-18KH, it's the 3-wheel riding scag mower. The problem is that it is leaking fluid from one of the axles on the hydrostatic transmission. It has an eaton 850 hydrostatic trans. I took the transmission out, cleaned it up, and even replaced the bearing seal where the leak is. I didn't see any evidence of damage in the bearing or case around the bearing. I have it all back together now and it's still leaking!

    What should I do next?

    I was fortunate enough to find someone on the web selling the seals (from New Zeland), but other parts might not be so easy to find. I've seen other older SCAG mowers on auction sites that had the same leak so I have to believe it's a common problem. Just not sure what the fix is!
