I have a YM240D with Yanmar loader and Yanmar Backhoe. The back hoe is ran off PTO pump. The problem I have is the loader is way slower than I like. It runs off tap in block on tractor hydraulics. What i need to know is the tractor loader system an open or closed system? What i want to do is operate the loader with the PTO pump for higher flows. Thinking I could quick connect the lines in some how depending on what type of system. I would just do it with the PTO pump but I do sometimes take back hoe off. I would appreciate any thoughts.
