Abstract: An irrigator for distributing a constant depth of fluid as the irrigator moves over an area. The irrigator has a moveable nozzle boom arm, a winch with cable and a governor. The governor is connected to the moveable nozzle boom arm and to the winch. In use the governor controls the speed of winch and the speed and movement of the moveable nozzle boom arm, so that application depth of liquid being applied by the irrigator can be kept substantially constant.

Abstract: An irrigator has a single irrigation arm adapted to move in reciprocal rotational motion. In a first setting, the irrigator sprays irrigating liquid at a first orientation with respect to the arm to move the arm in a first direction. In a second setting, the irrigator sprays irrigating liquid at a second orientation with respect to the arm to effect a reversal in the rotational direction of the arm. Alternating mechanisms are provided to alter the arm between the first and second settings.

Abstract: An irrigator (A) for distributing a constant depth of fluid as the irrigator (A) moves over an area. The irrigator (A) has a moveable nozzle boom arm (9), a winch (15) with cable (15a) and a governor (B). The governor (B) is connected to the moveable nozzle boom arm (9) and to the winch (15). In use the governor (B) controls the speed of winch (15) and the speed and movement of the moveable nozzle boom arm 9, so that application depth of liquid being applied by the irrigator (A) can be kept substantially constant.
