B7100 lift arm issue

   / B7100 lift arm issue #11  
I don't know about the B series, but my L series and my little Yanmar have a rubber hose that connects the suction line to the line coming from the pump. It is common for these to develop leaks and the 3 point will not stay up. I'm not sure if your are referring to the implement dropping or the 3 point lever dropping, but if it's the implement, and the B has a hose like I'm referring to, I would check that first.

Good luck and let us know what you find.
