The Stahl Liebherr (lower left), I was using it a month ago & the lower boom broke in half. The Stahl Cat (right), the 1st ever hoe I had is eleven yrs old, the pump/valves & undercarriage continue to work work properly, but everything else is pretty well shot! I haven't use it in ... a yr or more? I've gotten my money's worth out of those two and now I'm working on wearing out these other three in the coming yrs.
