Ponds and heavy excavation, over 20 years exp. this isn't a small machine so not looking for small projects for 1 day or 2. its costs 7k every time this machine moves. its 90k pounds. it can move a serious volume of material and get a lot of work done.
forget jack hammering rock, these excavators will rip right thru most bed rock and rocky ground.

overall rates vary depending on scope and soil type. the more feel burned the more it costs.
i don't use bulldozers but my heavily modified skid steers, there good at cleaning up and odds and ends. rates vary
