ABSTRACT:
Disclosed are turning tools for elongated agricultural irrigation pipes which lie along the earth's surface and which include longitudinally aligned gated ports along each pipe segment for radial water emergence therefrom. The pipe turning tool, which ensures that the gated watering ports can be positioned the appropriate distance above the ground, generally comprises: an arcuate shoulder for abutment against the pipe outer side, an elongate handle rigidly attached to the shoulder and extending rearwardly therefrom and away from the pipe, and a fixed positioned stationary detent extending downwardly from a rigidly secured header and which detent is engageable with a radial discontinuity on the pipe thereby effecting turning about the pipe central-axis. Alternate tool embodiments are disclosed appropriate for use with latch-recess type radial pipe protuberances and depending upon the latch-recess spatial relationship to the aligned gated ports.
