Hyd oil going into the tranny and after about three hours use, it is low enough that the hdy/PS quits. Drained the tranny down, refilled the Hdy and same thing again. At least we know why the PS didn't work upon arrival. Is the seal between the two the only access between compartments? If so, the seal must really be bad or gone to transfer that fast? Thanks....Dale

Dale - highly likely it's the seals/sealing ring on the transmission input shaft right behind the power director. There is also a set of double seals on the PTO shaft from the torque tube to the transmission housing but not likely that is the problem. I haven't seen anyone explain it thoroughly but my guess is the oil pressure used to engage the hydraulic power directors causes the quick movement of oil so fast once the seals/sealing ring breaks down.

Our 200 had the same problem but it would quit working after about 15 minutes. There is a seal that lets the oil drain from the front to the rear. It has to be split to fix it. We kept a small transfer pump in the tractor when itd quit wed pump it back and run it til it quit again. We did get it fixed correctly tho and it works great now. Ive heard it is a common problem with the 190xts 200s and 7000s. Grandpas 7000 did the same thing.
