I'm in the middle of spring plowing and have developed an issue with the 3pt lift on the tractor. After about 30 minutes of plowing, the lift gets slower and slower to raise out of the ground. After about 45 minutes I need to stop at the end of each pass and wait 15 seconds for it to lift. If I lower the engine rpms to an idle, it won't raise at all.
The fluid level is good and it is clear not milky. At this point its warm, but not hot and does have some bubbles in it. Flipping the lever between position and depth control had no affect. Adjusting the flow control knob also had no affect. It has no trouble holding the plow up when it gets raised.
About 400 hours ago I rebuilt the hydraulic pump and lift cover. I also changed the filters, fluid, and pressure relief valve. Since that time I have seen this problem occasionally if I max out the hydraulics, but it has never had trouble lifting the plow before.
Other than replacing the pressure relief valve again, I'm kinda short on ideas. Does anyone have any suggestions?
Thanks for looking.
