410 FEL Lift approx. 850#? This stone was definitely more than 850#. I could not lift it but, with approx. 2200# of roll back force at the tip of the FEL, I could chain it to the FEL hooks, drag it from below the house (sorry, too much to work with to be taking pic.'s) and then start figuring on how I'd get it up this little steep hill. The wheels started burying in the soft ramp. So, I sat and thunk a while.
