I just bought this mower and had it shipped from HD. When I took everything out of the box, I found 2 broken plastic pieces. One under the mower, the other stuck under the bottom box flap. I scoured every inch of the outside of the mower and the attachments and can't find anything broken. It obviously holds a bearing or something cylindrical. I was worried it could be something up inside where the motor mounts. But maybe someone can say it was just something from the factory and has nothing to do with that mower. Here are 2 pictures of the part. They 1.5" (4cm) long. Both parts are broken in 2 places, the clip or end of the circular part and the opposite end. The parts don't mate, so whatever they broke off of has the other part still attached.
