Hi. I have a Kubota kx91-3. I added a thumb to it. It is plumbed up to the thumb area and has a pedal for it. My problem is that the thumb will only move in one direction. I found that the valve will only pull and will not push to reverse the flow of hydraulics. Any ideas on how I would go about making it work both ways? Thanks
If your Kx is like some of the ones I've seen the linkage is mechanical , pull floor and check linkage movement. Follow hoses/linkage to control valves.
Did you install plumbing yourself or did you tell who you had do it that it was for a thumb. If they are anything like excavators it could have one way hydraulics for a breaker Sent from my SAMSUNG-SGH-I317 using Tapatalk
You probably have a single acting valve section
