I know because I have read a thousand responses I just can not get it in my mind.. I have a Case JX55 (yes the dealer is out of business). The joy stick is Cofle can not find enough information on it. The hydraulic connection is - Husco -H03A9798 - 86984716 - 9210B11c - International. Two lines from the joy stick. Red button on inside hand knob( I do not know what it does the loader works without pushing it in. Below the knob on a round directional plate is a small red and green button. I know I will need quick connect but will I need to replumb - add another joy stick, s selector valve kit or Hydraulic valve.

Thanks

There has got to be a Case or New Holland dealer that reads this forum that knows this set-up.

Thanks
