AC 720 equipped with loader and backhoe. The boom cylinder on the backhoe moves but under protest. It has some strange fittings going on. I thought it would be one line for extend and another for retract but this is strange and I wonder if something is going on here. I don't know what any of this stuff is. This is the only cylinder on the machine equipped like this.  Anyone got an idea?

Looks like some type of diverter block. I have no info on those back hoes. Finding a manual on it would really help. Since no one has chimed in give Brenda at SLI a call. She may be able to help you.
