MT4201, How to add rear hydraulics ?

[DENALIAKITAS]

I am looking at a box blade that has hydraulic actuated rippers but my tractor doesnt have any rear hydraulics. Is it possible to add them and if so how? Thanks

It is possible. Cut pressure line & install control valve in series with 3 point. Front half of line to IN on valve. OUT to back half of line.
