I recently bought a JD110 backhoe and I disconnected the backhoe to try out the 3 point hitch. I can't seem to get it to work. I changed the hydrualic fluid today, 2 hydraulic oil filters and the screen filter under the bottom of the machine. I don't have a operator's manual and I'm wondering if I'm missing a step somewhere to make it work. I just pulled up the lift lever that in my mind, would operate the 3 point hitch up an down, but I get nothing. I read somewhere on a post that there is an electrical plug that maybe unplugged or corroded from non-use. Does anyone have a solution?
