3pt problems on a M-4700?

[tnpete]

I have a Kubota M-4700, And if I lift the 3pt all the way up. It feeds back into the loader hoses. AS in you can see the hoses swelling up from the pressure. The loader is plumbed using the power beyond on the tractor. I bought the tractor and loader new. And it just started it this year.
If I only lift what ever is on the 3pt arms until the loader hoses start swelling. and then bump the lever down just a bit. IT kicks the pump out and all is well. Anyone have any ideals?
Fluids and both filters were changed out so its not that.

The 3-point hitch lever travel needs to be re-adjusted so the flow shuts off in the top position. One easy fix is to put a stop on the touch lever slot to limit how far up it goes. The stop will be almost at the top of travel but not quite. You'll still have full hitch arm upward travel. There is a way to adjust the lever linkage but I don't have the details for the M4700 - maybe someone else will chime in. But the up-stop method for the lever is quick and effective.

Thanks that is what I have been doing. I have the stop set. and when it touches it. I just bump it back down a hair. and all it well. But would like to get it adjusted where that is not an issue. As I have others running it at times. And they do not watch what there doing.
Hope someone can help out on the adjustment. If not I will have to load it up and haul it an hour to the dealer. Then $100 to do something that will more then likely take them 10 minutes.

Pete, I had a look at a M4700 parts book - the 3-point hitch control valve and feedback linkage setup is different depending on your serial number. I would recommend spending the bucks on a Kubota M4700 Work Shop Manual for your specific rig. Might pay for itself in avoided hauls to the dealer.

Thanks a lot I guess I need to find a place to order the shop manual. And get it fixed.
Where is the best place to order one?
