brush cutter

[dnube]

Probably a question that's been asked a million times, but I'm new to the forum so here goes. I recently bought a low flow PTO converted to hydraulic brush cutter. It has a case drain...which my skid steer doesn't have a connection for, but doesn't have a pressure relief h connector. I'm looking to add the pressure connector, but am confused on what I need and do I need to add a case drain return to my skid?
