I didn't put the pin in my ROPS when pulling my tractor into the garage and they grazed the top connector of my Third Selective Control Valve (SCV). This caused the hydraulic line to become disconnected and I cannot seem to re-connect. I've tried releasing pressure in the lines according to the operator's manual but it doesn't seem to work. How do I re-connect this line?\
