Today, I picked up a BX2816 snow blower for a friend, and it needs a new cutting edge. On this BX3816 snow blower, the cutting edge is mounted on the top side of the housing. I was looking at the similarities of the BX2816 blower, and my BX2750 snow blower, and noticed that on mine, the cutting edge is mounted on the bottom side of the housing. Is one of these blowers have the cutting edge on the wrong side of the housing, or did Kubota make a change in the mounting location on the BX2815 vs. the BX2750? I looked at the parts breakdown, and it shows the cutting edge for each the way that I have described, however, the orientation of the parts in the pictures is different, which leads me to this question. The part number for the cutting edge is the same on both blowers. thanks
