Just thought I would add. 3 weeks ago, I purchased the BG-08 grubber. We bought property and were starting to clear out around a pond. Lots of 1-4" locust, birch, and pines mixed in with a ton of clumped brush of some kind. Wasn't sure I wanted to spend the $50, but gave it a try. After 30 minutes of me running the grubber and my wife on the tractor, we could see the pond finally. After about an hour, I couldn't believe the pile of ripped out trees we had. We started getting into the clumping brush and while it was working, the grubber had to be put on individual shoots, or I gad to dig down a bit to try to get onto the root. I chatted for 30 seconds with the wife and we both agreed we needed to buy the chain grubber. We paused for an hour, then got back to it with the chain grubber. Other than being a bigger pain to take off the trees once ripped out, it worked much better on the small stuff. For a couple of weeks we have switched back and forth, but but over all very impressed with both. We only ran into one 4" locust that I had to use the backhoe on. Everything else popped right out.
Bottom line, we got both and would do it again in a heartbeat! Great product and a huge time-saver.
