ABSTRACT:
A sprinkling apparatus powered for movement along a row of spaced risers. It is guided along a path parallel to the risers without any physical guidance being provided in the spaces between them. A coupler engages each successive riser and selectively completes a hydraulic circuit between the riser and the sprinkling apparatus. Mechanical indexing and engagement of the coupler relative to the riser is used as a guide for modifying the direction of movement of the sprinkling apparatus in order to permit engagement of the next successive riser by the coupler. All functions of the sprinkling apparatus are automatically sequenced upon engagement of selected risers. Alternate risers can be skipped. Reversal of the sprinkling apparatus can be achieved by placement of stop mechanisms along the row of risers.
