Joe; We uesd Baker valves on both our 44b and GM back in another life time when they were used for farming. Its a great add on for an old JD with Power lift. The Baker Valve does not give you live power ( I had often wish that it did ). The PTO has to run to use the the hydraulics, and the PTO only runs when the clutch is engaged. The setup that we used had a Pioneer Coupeler on each of the two outlets. Our units were bought from TSC when they really were a tractor supply place. Your unit probably came form the same place as it also is equipped with Pioneer Coupelers. We always used two way cylenders. I think the way it works is when you move the valve foreward it routes pressure to the first outlet and returns in the seccond. When you move the valve in back it switches to route pressure out the seccond and returns on the first outlet. The rocker shaft for the cultivator lift is still controlled by the foot peddels. It't operation is not changed by adding the Baker Valve. I think the setup you describe with one hose can be converted to the two hose version. I think there is something that has to be done inside of the valve assemblly to switch to two way( like adding a plug or something ). I don't really know though as it's been well over 40 years ago that I installed those units. Have fun with the little B D.D.Post
