The Toro nozzle tree for the ProStream XL™ Rotor comes with a selection of 8 standard nozzles (25° trajectory) and 4 low angle nozzles (10° trajectory) allowing you to choose the right nozzle needed for the pattern of spray. Since the amount of water applied varies among different spray patterns, Toro’s Matched Precipitation Rate (MPR) nozzles allow you to customize the right nozzle for the job that will provide an even, consistent water delivery and better water efficiency with other rotors that may be set to different spray patterns.
