ABSTRACT:
A step-by-step rotary sprinkler head having an impact arm with a drive spoon thereon. The drive spoon is preferably of the anti-backsplash type and includes a pull-in reactant surface and a drive-out reactant surface spaced radially and laterally outwardly of the pull-in reactant surface. The pull-in reactant surface has a slot formed in the central portion thereof for enabling a portion of the stream issuing from the sprinkler head outlet to continue its movement into the slot and outwardly therefrom without being deflected onto the drive-out surface when the drive spoon is in stream engagement so that the reactant force established on the drive-out surface is reduced in relation to that which would be established by the deflection of the entire stream thereon.
