How to Adjust the Arc on a Rotor Sprinkler

The design of a rotor sprinkler's head used in a lawn system allows the sprinkler to spray water in a more uniform pattern than stationery spraying heads. This makes rotor sprinklers a better option for watering larger lawns. Rotor sprinkling heads are equipped with a variable arc adjustment control that allows water coverage of between 40 and 360 degrees. The range of adjustment is convenient when areas to be watered have structures present. You can perform the desired adjustments on the rotor sprinkling head with the proper tool.
