Even on your other circuit you are running a orbit motor? Running a auger? So pump is running a fair amount of time and not only a few seconds. Most likely the previous owner never knew there was a problem if he never ran orbit motors. This problem with a T tractor is that the hydraulic pump is inside the rear end case. Not on the outside like a wheel tractor. So the valve as the previous poster explained that cured his problem is not easy to get at. We took both of the pumps we had problems with to a hydrostatic repair shop. Our pumps has internal leakage and scoring on the metal to metal sealing parts. They remachined if that is what you might call it those parts and put in a seal kit. Cost about $800 at that time.
