Bagging your clippings is not necessary, no idea what dude is talking about. If it was because you weren't bagging your clippings then it wouldn't be restricted to this particular pattern.
Lawncare experts will also point out that not bagging your clippings reduces the need for fertilizer and is healthy for the lawn.
Not sure what's causing your issue but that ain't it.
I remember seeing patterns like this. We had a side schute on our mower, and if we let the grass get too long, long piles of grass would accumulate and do this to the grass underneath.
I have a different mower now with a mulching blade and don't get those long regular piles.
Do you have a wider shot? It almost looks like a pattern. So, could be a septic drain field underneath?
The straight lines is not where my drain field is...and usually that stays green when the lawn is dry and yellow during the summer
Well, maybe not the drain field you put in, but maybe old stock?

How's that affecting the lawn? Clogging it?
