Ive been using my walker mower for the past few years on bermuda grass that is dormant. I lower the back to the normal cutting height and raise the front to about an inch higher. I do this because i generally use it to pick up leaves and debris in the winter but by keeping the back of the deck down it will cut the tips off the grass. My question is.......does this hurt the dormant grass later in the season when it comes out of dormancy? Most every business in Ga does this because it keeps the property nice and clean looking. I haven't noticed a problem with there grass.
