    How do you find the LW-8? I have a LW-7 and while it is serviceable the control valves are very jerky, especially the swing. This BH is several years old and things may have improved some. Also I modified mine to run off the tractor hydraulics.

    When ordering a new narrow bucket for mine I found out that the LW series Backhoes are made by several factories in China and not all are the same. I ordered a bucket from Circle G and it did not fit and had to go back through Chip to have him order one from the original maker.

    The LW-8 works good ... lots of power and more reach than the smaller Nardi backhoe.
    Although it lacks the refinements and rigidity of the Italian backhoe, it digs great. This one was purchased in 2007 by my friend Scott when he and I got together and bought his tractor and Loretta's tractor, plus a whole container full of implements for each of us. He sold his tractor and I ended up buying this backhoe from him along with a bunch of implements. So it is probably older or as old as your LW-7 maybe?

    If you click on that link in my very first post in this thread, you can read more about the LW-8 and the Diamond shaped sub-frame I made for it to fit the 554 Kama.

    The hydraulics can be tamed just by adding restrictors in the circuit you want to control with no sacrifice to power.
