FIS outdoor in Wildwood sells the round concrete donuts in two sizes. They are located by Russell Stovers. We installed them ourselves by purchasing a grass remover tool specifically made for sprinkler heads from Lowe’s.

And there are a couple places I don't care about where I am sure there must have been a sprinkler head once but I'm too lazy to dig up the yard to find it.

What the heck causes that? I'm from Houston, where everybody also has a St Augustine lawn, but I've never seen this before. If the ground is sinking, why is my house just fine? Weird!

For less than $2 per, it's cheap protection for your heads.

Depends if you have walk-behind mower or heavy riding mower.

Depends if you cut out your heads or not.

I have a new house in Lake Denham. I see these concrete donuts are a big thing around here. I live in Massachusetts for my main home and I've had irrigation systems for 30 years. Never had any donuts around the sprinkler heads. I've been using a John Deere riding mower over mine forever and no issues.

Is there something different down there in FL?

I don't know how many times I've seen groundskeepers adjusting sprinkler heads along Morse Blvd, Buena Vista and Meggison Way. If lawn mowers didn't hit them, how did they get out of adjustment?

Been pondering the same. But, my assumption was that the ground level was somehow rising rather than sinking. Does dirt grow? Can thatch become dirt over such short periods? Tectonics would drag the sprinkler system along with it, no? Can grass roots raise the dirt level? (They'd wait a million years. . .).
