Need advice. I am going to tackle adding another set of hydraulics to my M7040. I have found a new spool valve for 124.50. A hyd top link for 287.00. Female quick disconnects for 18.00 each. I have a friend in hyd hose business. What else do I need? Can I tee off existing hydraulics or where do I add more? I am determined to add this extra set of hydraulics so I can tilt bale spear for more efficient operation. Thanks in advance.
