I have a B21 commercial TL421 loader, BT751 backhoe. I want to add a FEL grapple with a valve control mounted on the ROPS cross bar. The FEL control valve looks to have a Power Beyond off the rear marked with green paint that goes to the backhoe. The pressure input and tank return to the FEL valve are steel. I think I can disconnect the PB from the FEL and attach to the single lever valve for the grapple and attach the PB back to the backhoe. The problem I see is that the return to tank from the FEL lever is steel. How does one install a T in a steel return line without removing it, cutting it, and having someone weld a new end on the steel line. The backhoe has a hose return, but its a ways back to it. Is that an option for the return. Or am I looking at this totally wrong. Thanks, Hydraulically lost.
