ABSTRACT:
Disclosed is an improved sprinkler arm rotatable in and out of a stream of water. In particular, the reaction surface of a sprinkler arm's spoon is improved to direct more water close to the sprinkler. The reaction surface in the preferred embodiment is provided at least one groove which directs some of the water downward from the rest of the water exiting the reaction surface. An alternate embodiment employs at least one pin in the reaction surface instead of or in combination with at least one groove. The improved spoon applies more water near the sprinkler ("enclosed water") without interfering with maximum distance of the water when the arm is rotated out of the stream ("canon shot").
