June 4 2014 update
This particular blade broke on its third rental. One tooth was torn off the tooth next to it was almost completely torn off and a third tooth has a slight crack a fourth tooth has a very tiny crack. The vibration loosened the hub and the blade and blade hub came off the drive shaft. Fortunately the blade enclosure held the blade within it. As describe further down in the posts if the blade hub was ether a one piece design or welded together the blade would not have separated from the drive shaft.
Cost is one more $200.00 blade and $40.00 labor to remount the hub.
