A couple of things: Directions did not mention removing the trim side baffle. I had to assume that it should be removed. It did say to remove the discharge baffle. Also, there seems to be a lot more vibration. I have a mulch kit on my Metro HP 36" and I love it. I did not notice an increase of vibration on it though. Does the fact that I am sitting on the mower instead of standing behind it have anything to do with it? There are also 2 Plate Blockers (I believe that is the name of them) that were to mount in-between the front of the deck and the front of the baffles. Does anyone know what the purpose of these are? They seem useless. It doesn't clearly show how to install these but I think I got it right. Finally, there is a rear plate that attaches to the rear of the deck. Again, I do not know the purpose of this plate. It seems to be adjustable (up and down) but the directions only show one position. Also, when mounting the plate, it doesn't sit flush with the rear of the deck because of some brackets. So, there are 2 bolts that when tightened, bend the plate. It does not seem right.
