"The Warden" has cut mine for ~ 20 years, now.
Set it as low as possible - and mow it!
That all started the day I had to wait 2 hours, or so to get a parking space near their shop. Then 2 hours in the waiting room. Next, I figured out the barber lady was trying to cover an acre with 4 cornstalks. And realized I had to replace my comb (lost one every year going around fence in the spring)
I'd just had ENOUGH !
