Hello, new to the forum, looks very interesting. I have a 1990 Bobcat 440, complete restoration done, but I have a question about adding an auxillary hydraulic set up. I want to add a spool valve in the cab to run a wood spliter or a thumb to a grapple. Can I add a T to the main line coming off the pump and a return line T'd into the main return? Just wondering if anyone has done this? thanks
