It is only a year old and runs fine and starts on first pull. Blade is sharp, front tires is set to one notch lower than back tires (i.e. back is 1/4" higher than front). I thought it would get better once past wet grass season but is the same. It leaves uncut grass strands and clumps of grass like it was pushed down and only partially cut off the top. I'm not sure what is under the big plastic housing under the deck in the middle of the mower but I was thinking about taking that off if it doesn't hurt the mower and see how it cuts. Still has those kickers under the deck. Still has standard blade that came with it. Any ideas why cutting bad?
