Hello, I hqave a MF231. I recently purchased MF 232 loader and am trying to tap into the internal hydraulics to power the loader. I purchased a hydraulic selector valve but it doesn't have a return port back to the selector valve form the loader control valve. The 3 ports shown only supply 3 options for pressure as far as i can tell. Can anyone help me with a place on the tractor hydraulics case or transmission that i can hook my loader control valve for the hydraulic return? Or is ther a better diverter valve i should be using? This vale replaces 180908M1 INTERFACE COVER PLATE WHICH IS LOCATED ON THE HYDRAULIC LIFT COVER. Thank you for any help!
