A rotary irrigation system moves continuously across relatively large areas of land while the areas are being sprinkled. One end of a relatively long length of horizontal tubing is pivotally mounted to a vertical pipe containing water under pressure and the other end of the tubing is connected to a power mover. The tubing is provided with a plurality of sprinkling heads spaced throughout its length and is supported above the ground by a plurality of carriages so that the tubing can be used to irrigate an area of ground which is not completely flat. Each of the carriages is supported by a single wheel. A cable connected between the vertical pipe and the front end of the power mover causes the power mover to travel in a circle around the vertical pipe with the power mover providing an outward tension on both the cable and the tubing.
