Excavator Will Outdig a BH by far.
But do you have the work for it?
I have an excavator, purchased late in the game hogging our farm out of a chunk of NH rocky ridge. Still it paid for itself. Used it a lot.
However, Costly upkeep. Real expensive to repair.
Now that the farm is established, I should sell it, but I want decent money for it.
Even though it is worth it, buying it is risky, so people offer low.
Problem is anyone who buys used takes a big chance.
I take a big chance keeping it, as if it breaks, it's worthless.
Still very handy to have, but I put just 100 hrs on it in the last 3 years, vs 500 hrs/yr previous to that.
You have to figure cost to rent vs buy.
I would not recomend 3PT BH
