Oscillators are ideal for watering large, rectangular areas. The Easy Click dial adjusts the watering pattern area allowing the sprinkler to conform to an array of yard widths and lengths. Choose from full, partial, left, or right coverage. The oscillator features a heavy duty planetary gear train and smooth-action cam drive for lifelong performance and reliability. The wide base has been designed to make repositioning easy and to reduce tipping during watering. There are 17 spray nozzles providing even watering coverage without creating puddles. The plug at the end of the spray tube can easily unscrew to reveal a clean-out tool used to clear clogged jet nozzles.
