did you measure the blades to see if they are correct? how did you measure deck level? when you rotate the blades the tip should come pretty close to the one next to it, from the looks of it I would say either blades are too short, not to ask stupid question but do you have the sail of the blade up in the deck? meaning blades arent on upside down? those are pretty extreme mowhawks, when you rotate the blade tip to the one next to it are they at the same height? I would start with having wrong blades possibly, then I would compare height of blades to the ones next to them. That is definitely not a "level" or "pitch" issue. and make sure when you level the deck you are not measuring off the pan, measure off blade tips. and you want 1/4 to 3/8 pitch also front to back as well... front of deck being lower than the back. level should only be side to side, not front to back. I would start with the blades. did you possibly hit something and tweak the deck where spindle sits, thats where I say make sure the blade tips are at same height as one next to them, have had to take the persuasion mallet to some decks through the years at my shop.
