This means that the grass blades will obstruct the water streams resulting in less coverage. Hunter does produce a 6” rotator, but installing these was not an option.

Yes, I have experienced this very thing here in Dabney. I started out with some 1 1/2" extender tubes that connect between the top of the sprinkler tube and the head, but those create another fine thread joint that could leak or fail over time. They are called KAP-ITs and can be purchased from Wal-Mart in a 10 pack for around $35 (link below). The better solution is to raise the sprinkler heads up about 2" or as high as you can without them getting dinged by a mower blade. You will have to dig down about 10-12" with a trenching shovel and when you reach where the flexible hose is, pull the entire head up gently about 2" and push some sand underneath that gap, pack tightly, and refill the hole. You will likely need some additional sand to completely fill the hole you dug out and to get the head exactly where you want it, so it is helpful to have a bad of sand handy before you start. Not a bad job, takes about 10 minutes per head once you do a couple of them. If you are not using donuts, you might consider those as well. They are not great since the St. Augustine quickly grows around the donut and inside it, but if you clean and cut the turf around them a few times a year, you can at least see the sprinkler heads and make sure they can pop up freely without the wiry grass vines stopping them. Still not sure why they didn't go with Zoysia grass down south, but I am sure cost was a big factor.
