I have a 95 MF 231 with the 232 front end loader and I am needing to replace the 2 hydraulic couplers. Do I need a single or double acting coupler?  Not really sure about the difference. Can anyone provide the amazon or tractor supply link?  Not sure which one get (assuming both are the same). I am trying to order before returning to the farm where the tractor is. Thank you!!
