At work we build a ton of boulder egresses on new construction with a PC30 Komatsu or more recently a Bobcat E35 both with thumbs. If you're talking legitimate 3ft rocks in all dimensions then you definitely need a bigger machine. If you're talking 3ft in the widest and only ones that'll be on the bottom row you may be OK with what you're looking at. It seems for most jobs that the size of the excavator isn't going to determine whether or not you can but just how long it'll take. You may need a 10 ton plus excavator to move a few rocks around, but what then? every other task couldve most likely been done with something smaller and 20 grand cheaper. What kind of walls are we talking relative to these?
