Does anyone else have issues with an uneven cut when on a slight slope? I have a D130 and our back porch has a slight slope away from it. If I mow it parallel to the porch, it will create an uneven cut no matter what I do. I tried lowering the deck rollers and tried raising them. I mow from 2.75"-3" so according to the manual I had the deck wheels down to the lowest level. You can see the uneven cut in the picture. Is there a way to prevent this besides mowing perpendicular? It may be hard to see the slope in the picture.
