I have driven the tractor and noticed a few more things. 1) the pto clutch had aftermarket disks in the clutch pack. When engaged, the piston bottomed out before applying sufficient pressure for the torque available. Either the pto brake or the clutch has a pressure of 145 psi (cold) to 125 psi. There are radical changes in pressure when shifting the rabbit turtle. No difference using the steering wheel. Does drop when using 3 point hitch to 80 psi and snaps back up.
We put the pressure gauge in the transmission lube circuit. There were times the pressure would drop to 0 and for longer than I thought reasonable. I also didn't see a pattern behind these pressure drops. Pressure range goes from 0 to 110 psi. My guess is an average of 50 psi.
We had the gauge in the pressure port from the transmission pump and as before, ranged from 125 to 145 psi. Yesterday there were a couple problems shifting into rabbit where I had to finesse the handle for it to engage properly. The 3 point hitch didn't pick up the plow a couple times. I had to stop and wait. Same thing with flipping the plow. Engine RPMs were 2400 or normal PTO speed. The remotes gave me more trouble than the 3 point hitch. Today I went to plow and (cold) I couldn't flip the plow. Then I tried to turn and the power steering was jerking as if the pump was starved. The reservoir should have been full running the engine at 1700 RPMs for over a minute. I parked the tractor.
Early history of this tractor. It was involved in an electrical fire. The wiring harness and dash and starter was replaced. I don't know of anything else. The damage was light but maybe some valve got compromised.

Today's Featured Article - A Lifetime of Farm Machinery - by Joe Michaels. I am a mechanical engineer by profession, specializing in powerplant work. I worked as a machinist and engine erector, with time spent overseas. I have always had a love for machinery, and an appreciation for farming and farm machinery.
