I would also highly recommend an excavator. You can basically just drive around to and pop out stumps as you go. Positioning the BH for each stump by comparision will probably be too time consuming. Attached is a pic of the machine I recently rented (JD 160, 35,000 lb) for a week to pull stumps on a little over 1.5 acres. It took 4 good days with myself and another guy operating the machine to get them all out and buried. Get one with a thumb if possible. The place I rented from did not have any large machines with thumbs. This made picking up and transporting the stumps to my pile more difficult, but if you have a helper that can use your tractor to move the stumps that might save you some time. But something that might hamper tractor use is that the root ball even on pretty small stumps makes them very awkward to handle (may have to chain into loader bucket). Also they can be very HEAVY! /forums/images/graemlins/ooo.gif Another thing that may be helpful is to go around and use some fluorecent marking paint on any stumps that are cut close to ground that might otherwise be hard to see. This was my first time using a full sized excavator and it was an absolute blast to run /forums/images/graemlins/smile.gif I was sad to see it go back to the rental yard.
