I have to tell you the good and the bad. I was very excited about my new blade. Well packaged with good instructions. It was very sharp when installed so I had to be careful. Now for the bad. I did a test run and the right side of the tree was cut very roughly. I understand that he has a bad weld. I found the weld, everything is fine. So I continued my inspection. One tooth turned out to be COMPLETELY uneven and bent. I bent it as best I could and now it cuts fine. I think I was expecting a very high quality blade but I was disappointed with this one. I am not sure if I will order again
