I bought my LazerHP (52", 23 Kaw) last year and it performed great. This season, I noticed a very slight uneven cut...on the very outer edge of the discharge side of the mower (no mulch kit installed) about a 6" stripe of grass is cut, but not at the same level as the rest, its about 1/2" taller. I have the deck set to 3", and the uncut part might be 3.5". I leveled the deck slightly (lowered the non-discharge side about 1/4" )and this did not solve the problem, plus I would suspect that the entire cut would be uneven, not just a 6" stripe. The blades have been balanced and sharpened. The only thing I haven't done is check the tire pressure. Since I just noticed it this season, could it be tire pressure or something else? I don't see any visible signs that one tire is less than the other. Thanks for any hints.
