Ditch Witch Model 140 Backhoe

[Master Chief]

I have read that several people have converted a ditch Witch 140 backhoe as an attachmnet for a Skdsteer or as a 3 point hitch. My question is with regards to the hydraulics. My backhoe attachmnet has three hydraulic lines, two the left side (if you would be sitting on the attachment working the controls) and one line on the right side. I believe two lines are return and one is suplly. But I am trying to figure out which is which. Thanks for any help. Master Chief

Can you post some pictures of the hyd valve and where the 3 lines go into the valve.
