    You only need to raise the deck if you have a lot of extra clippings piled up. Under normal conditions, you can leave the deck at the same height and roll on.

    If and when I have to double cut I leave the deck at the same height.

    I feel sharp blades and bagging saves me time and fuel. I have dumps spots on many of my properties and when I have to take clippings away, I have a free spot that is 2 driveways down from my place. But, we can save the mulching/throwing/bagging debate for another time.

    I have a different theory on this. If I am double cutting for stragglers or such I leave the deck the same height. If I am double cutting to spread clippings I raise the deck .5 to 1", depends on how much needs spread out.

    Same as Turf Dawg, I raise the deck half an inch to spread the clumps and piles of clippings. Just enough to clean up the bulk laying on top, not suck up every blade you cut. Depends on the deck I imagine, but on my old lazer it cleaned up nicely, while letting me go like the dickens, and easier on the machine with the deck up a bit more.

    Two approaches.

    1. Mow slower the first pass and make sure you get a clean cut so the grass is nice and level. Second pass mow 1/4" higher at high speed to clean up any clumps.

    2. Mow medium speed first pass, accepting that you may have some spots where thick grass causes stragglers, etc. Second pass mow at same height, again at medium speed, ideally with perpendicular passes, and both disperse clumps and smooth out any missed areas from the first pass.

    I raise the deck almost every time on the second pass. I'm almost always just trying to get rid of extra clippings.

    Yes 1/2" higher on the second pass really makes clippings disappear.
