JD 2240 3 PT control?

[ben hoops]

Did anyone ever figure this out. My 2240 started doing the same thing. Start the engine 3 pt goes up, shut engine off 3 pt goes down, takes forever to lower any attachment I put on.
Thanks
Ben

Yup, control right in front of the seat is the Rate of Decent valve...if you want to call it that. To the right of the seat is the draft control, and this should be in the top hole...all the way up do defeat the draft control. Far right control is the up/down for the 3pt. I had to go all the way thru my 3pt at about 5000 hours replacing valves/seats/and springs. Not a big job.... Mine was doing the automatic up/down pulsing thing. But I bet you are in for a run to the JD dealer for some little expensive parts...... Everything is in the top casting that the seat bolts to. If your bottom 3pt seals are leaking where the shaft for your two 3pt drag arms go into the main casting....this is a great time to deal with them, too. Since you will be dumping all the fluids. Me, I forgot...and mine still leaks some....... Good luck, ,Jerry...

Sorry for not updating this thread. I ended up doing a rebuild on the 3PT. Here's the thread on it. http://www.tractorbynet.com/forums/hydraulics/174760-jd-2240-rebuilding-my-3-a.html The gist of what I was experiancing was that my lift valve was leaking and putting pressure to the cyclinder.

The rebuild was pretty straight forward and simple. IIRC, the parts weren't that expensive either. Under $200 I think.

Keep us posted on what you find and how you address it. You're welcome to use this thread for it if you wish.... or post us a link to follow.:thumbsup:

Thanks! I will be back at our TN location Monday. Will take a look at the adjustments, hope thats all it is. This is my Fathers old tractor and has not one marking. He has lost the manual and very likely messed with the controls. Unlike our tractors in Florida and our Case in TN this unit does not have the little turtles and rabbits on it :confused2:
We will post our results.
Thanks again

Nice write up/pictures on the repair Cyril... I am impressed. You have been pretty busy since you got that tractor a few years ago. Time for another..????

Thanks for the compliment. As for another tractor, I've still got lots I can play with on this one.

We adjusted the ROD and moved the drift to top notch and everything works perfect. BIG THANKS!
