I have a BX25D with a BT601 backhoe. I was digging up some stumps today and it was hard going. I'm digging around the stump as much as possible and a couple of times got the sawzall out to cut a few roots. My question is, how far can you push the hydraulics before you damage something. More than once I found a root that was not going to break. I would hook the root and tug a little. The front end would lift up a bit or the leveling legs would slide. It was obvious that the backhoe was not going to win so I backed off and kept nibbling away around it. Question is, how far is too far? Not sure how much I can push the hydraulics, and I really don't want to damage anything.
