This is a 2 part question...Weather below freezing yesterday morning, Started the 190 up from sitting all winter, had no hydraulic pressure anywhere, ie: steering, clutch, loader and PTO. Checked the dipstick and found emulsified oil on stick. Later in the day after temps warmed up, went back out and tried again. This time everything worked as it should except the PTO. My question is, how do I get rid of all the emulsified oil without excessive cost of oil by repeated flushing of the system? Also I was informed the PTO has not worked in about 5 years. How do I troubleshoot this PTO system? I know that the hydraulic pump is 2 port, does the pto have a dedicated port? I have read that the pump housings wears out and system pressure drops with the wear. What kind of pressure should I see on the hydraulic system and where is the best place on the tractor to get these readings?

After sitting all winter, it's quite possible for the pump to lose prime on a unit that old. The pump is above oil level,in fact, the highest point in the system I believe. Body seals get old and shrink in cold temps anyway. Earlier models had a strainer in the suction line with connections and clamps(more places for air leaks)as well as the rubber inlet hose at the pump. The hydraulic system is not all that large, as it's only the front torque tube housing. The trans is a separate compartment and the fluid are not supposed to mix. In the future after replacing with clean fluid and checking hose connections, you still have trouble with priming,you might consider pump seals. Also might try loosening the pump output lines a turn or two on your first spring startup, run the tractor a few seconds to bleed out then tighten the lines. As for the PTO, if it has a clutch pack, it's in a sump box under the belly. The PTO valve like the power director valve has 1/8" pipe plugs in the test ports for checking the clutch pack pressures. The high, low, and PTO clutches should read about the same if all is well, as the supply is the same for all. Not sure on the spec, but I'd expect around 180 to 210 PSI. You can also remove the pressure supply line from valve to PTO and air check the clutch pack. If the clutch is OK, you will hear a thud when air is applied and the system should be fairly air tight. If you hear a lot of air bleeding off and noise out the dipstick port, the seals are probably bad.

Today's Featured Article - On the Road with Dave Gohl: Deere Departed Friend - by Dave Gohl. Have you ever had to part with a dear friend? It's not easy. If it's due to death, your feelings could be in disarray for days, months or even years. Even now after almost 4 years, I still miss my dad. I remember when I was a kid my dad sometimes would tuck my brother and I in at night and we would ask him questions about his childhood on the farm. To this day, it's some of the best stories I've ever heard. And now, I'm so glad that I asked those questions, and if I were a little smarter i ... [Read Article]
