Have 1 way hydraulics on stick---what can be done to put a hydraulic thumb on this machine. Thanks.
Guess no John Deere mechanics around thanks anyway.
Good day Follow the line back to the valve chest if you have the opposing line plugged it is not difficult. If you are unsure post a pict. with the valve illustrated. Kind regards Uffex
I've not done one on a 690 so would have to look at a book to see how much different it is than the standard Deere/Hitachi. With one way hyd. on the stick basically all you can use is the tubing. Depending on how it's plumbed, you need each line coming from the aux. section of the control valve. Then you need a DO3 solenoid valve, A&B ports open to tank. This runs your pilot system on the control valve. You also need port reliefs and will need a two way joystick handle.
