I have been digging a pond for two years. We have been using my skidsteer, backhoe, and 12 yard dump truck. We were making progress but slowly. Today we brought him the big guns. A Deere 850k dozer, a Hitachi 300 excavator, two belly dumps plus my 12 yard dump truck. In about 3.5 hours we hauled off 45 loads of dirt. Amazing what big machinery can do. At this pace we might finish digging tomorrow.
