I've got an l3800 with a BH77 backhoe attachment. I was doing some work for a guy and using it pretty hard and blew a hose. My hose guy was closed, so I just quit for the day. He called and told me that he had gotten a hose made and installed it for me. I dont know if there was some trash in the line when he installed it, I broke something in a vale or what, but now the backhoe doesnt want to draw itself back to me. All the other functions seem to work fine. I can pull it a couple times and it will work, but it acts really weak. What could it be?
