Landscaping/Yard Care Question

I did pretty much the same on what would equal 1/4 of my yard, if the spaces were all added together. We had a ton of little dead spots, ranging in size from 3" circle to over a sq ft. It looked a little odd at first with all of these dirt piles across the yard… but it turned out nice and we had a “whole” yard. Granted I haven’t done anything but cut it since… (6 or 7 years ago now)
