It is possible that two hoses could be hooked to those ports, and then to a cylinder to control it. Any part numbers on the valve?

Sorry, no part number. The small sign is gone.

There is a free parts book on the JD web site .
It does appear that the hydraulic system is being dead headed with this additional valve. As previously stated something wll eventually become over heated and ruined in the current configuration .
Usually Deere lists 240V block and transmission heaters .
Philips and Tembro list every size , shape, voltage and wattage of both oil and water heaters .

That is what i am afraid of, so i would like to remove it. But then i need the filter attachment i guess.

I try to find block heaters here with 240V, but the only one i find so far is Defa, but it doesnt have the possibility to "rotate it into place" (missed a word

). It is only made to replace a frost plug, and knock it into place with a hammer. I dont like that to much...

I believe the OEM block heaters are made by ZeroStart, not sure that will help you "over there"

Thanks

But have trouble finding the right one. Anyone know the size of the plug?

There are the letters: P (x2) and T(x2)
The line is connected between P and T (Two of them). A and B are plugged.

P=pressure, or IN from the pump
T=tank, or OUT to the sump

A and B are probably the work ports that would get hooked to a cylinder.

Thanks

I need a 6/2 valve to get an extra output for the back-blade. As i understand it, i need another valve then...

I ordered a hydraulic sylinder today, so with some welding i will be able to turn the back-blade in both directions.

Got a little further now. I finally decided to remove the valve, so i replaced it with a hose. Problem solved

I also mounted a block heater. A DEFA with 1". Thanks to this forum, i was able to find the right size. The lokal dealer only had the one for fros-plug, but now i have found the type with the right threads. It was quite hard to put it into place. the pipes had to be bent a little. But it was possible, and im very pleased with the solution.
