I was clipping pasture with my 2940 the other day. I had the 3 point raised and when I was done and idled the tractor down the hydraulic pressure light came on and the hydraulics were slow and cattery. When I looked in the hydraulic filler with the 3 point raised I saw oil spraying it looks like it's coming from the 3 point cylinder. It stops spraying when I move the lever down an inch or two and sprays when the lever is all the way back. After the tractor cools down all hydraulic function is normal. I have noticed a few times when starting it cold the PTO is running with the lever in the off position, when moving the lever to engage the PTO and back to off the PTO stops turning. What kind of a project is it to replace the piston seals on that cylinder? I assume it wouldn't be too bad once the seat and rock shaft cover is removed.
