The pb runs to the wr long valve for grapple out the wr long valve to the backhoe then back to t when backhoe is hooked on when. When backhoe is unhooked jumper is in place the backhoe input is connected to a line back to p easy to say hard to explain
I may be your quick couplers if any would have trouble with Fel after brush mowing connections would get bumper but not enough to disconnect gust push of center you can switch hoses around see if the problem moves
I was going to take off the power that control grapple through a w r long switch. So it would go PB to w r long switch and take the P from switch back to backhoe PB input and then from backhoe P back to P input on tractor will I have any issues thanks
