I posted prior about this issue this season.. I have a 61" deck, its always cut pretty good, discharges to the Right.. the two "left" blades were cutting very poor, missing 80% of the grasses high or low. I was running a mulch kit and had two normal blades on that side, and a gator on the discharge. I switched to all gators again, same problem. I removed the mulch baffles on the two right blades the other day and cut with it on tuesday... same deal, 3 gators, all sharp, just as it comes from the factory minus the blades and even going half speed, 5mph~, it leaves huge areas of uncut grass on the two left blades, the right discharge blade area is flawless though, any ideas? The deck is pretty clean underneath, no buildup, at least nothing major since i last cleaned it out a week ago. Im stumped :/ Both my 48" deck with all gators and the new 72" with all gators cut damn near perfect.
