Then, why is my hunter sprinkler head not rotating?
When in operation, water turns a small turbine in the base of the sprinkler, which drives a series of gears that cause the head to rotate. The Hunter gear drive mechanism is sealed from dirt and debris. Generally, if cleaning the filter does not solve non–rotation then the sprinkler must be replaced.
