I have tried every Hydraulic connection for the Backhoe to my tractor.. I have 4 hydraulic connections on the back of my tractor for the front loader. I disconnected the bucket two lines and installed the lines from the hoe didn't do a thing. I have tried all of the different ways to connect it. Please does anyone have an idea what I should do. I don't have the two remote Hydraulic lines that stand alone on most machines. Do I have to install a PTO pump ?? Thanks for any help !!!
