i had to use another computer to see what you were talking about. your right, it's the second picture your talking about i hope, but it wasn't the trimmer. this lawn was ruined by the ladie who owed it a month and a half before this picture was taken. she decided to put glyphosphate down thinking it would kill the weeds, sure did, including the lawn. i showed up to mow the lawn and she told me what she did, i had to look at the product to answer some of the questions she had. This is how i know she used roundup. so i drenched the lawn for a good day and took a soil sample, just so i could sell her on some other improvments. i threw down a quarter ton of lime her PH was 3.2, I knew it was low but thats unacceptable. I also put down 80 lbs of urea to speed up the regrowth time. anyways theres still parts of that lawn that havn't recovered completely and i think thats what we are looking at, but maybe not.
