I was hoping to put a cessna valve from a John Deere loader onto a ford 3000 tractor. the john deer valve is alot smaller than the one off the Ford. Smaller inlet and outlet and spools. im guessing that wouldnt work ? what I want to do is put on a valve that would have down pressure on the lift arms. the one that came on the loader did not. Have changed the lift arm rams need a different valve.
