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.
