Tilling is the process of preparing soil for planting. If you are planting a lawn from scratch, turning part of your lawn into a garden, or reseeding bare spots, you will need to till it. Good and thorough tilling is very important for good lawn growth, or in fact growth of anything you plant.
Weeds thrive closer to the surface of soils than grass. If the soil in your lawn is less than four inches deep, grass roots cannot penetrate the deep ground to establish deep feeding roots. Four inches of soil is an absolute minimum for great growing organic grass. Eight inches (or even more) is preferred. Without deep soil, grass will dry out quickly and die off easily.
