I realize this is an older post, but I have had the powerking stump grinder for about 3 years. it has been great for my use. We purchased 25 acres that was completely wooded. We've cleared several acres and used the stump grinder to take stumps below ground. I've replaced some of the teeth recently, and replaced the carburetor to fix a broken choke plate. It is a workout to run it all day, but overall I have been pleased with it.
