Why does my impact sprinkler leave a muddy center and dry edges?
Impact sprinklers drop most of their water right next to the head while throwing the rest far out, which creates a saturated mud pit in the center and leaves the outer radius completely dry. This uneven distribution prevents the lawn from receiving consistent moisture across the entire watering zone.

“I’ve got one as well and the distribution is terrible…shoots it long, middle doesn’t get much, and then 2 feet around the sprinkler is a mud pit”source ↗
“The center is obviously very saturated. The left side water seems to apply well enough, but the remaining 230 degrees or so on the outer 1/2 of the radius just don’t seem to be getting much retention of water”source ↗
