I can't believe you don't shut up!

Can someone please explain to me why the grass near my apartment needs to be mowed constantly, and the grass bits blown around with leaf blowers after? I can understand if it happens occasionally, or for short periods of time, but the noise has been going on for more than two hours now. And this is after two hours of it yesterday too. I'm losing my mind. Or at least I think I am. It's possible it is still there but I just can't hear it over the lawnmowers.
