I am having touble with the cut of this lawnmower. When sitting on the lawnmower the right and center set of blades cut great; no complaints at all. Then there is the left set that cuts uneven every single time I use it. I sharpen the blades very frequently and have tried the regular blades alone, along with the regular blades doubled up with the wavy blades. Both ways cut great on the right and center sets, but the left set is awful and its driving me nuts. I am assuming it has something to do with the suction, but I dunno what is sold to fix it. If anyone has the answer to this please let me know, thank you..I understand it is not a top of the line machine, but I don't think it should be cutting even like this. I am just frustrated with it at this point.
