摘要：
A nozzle height adjustment subsystem for use with an irrigation system comprises a spool, a rotation device, and a control device. The spool includes a central hub and is configured to retain a drop hose to which a nozzle is attached. The rotation device is coupled to the spool and rotates the spool in a first direction or a second, opposite direction when it is activated. The control device includes electronic circuitry that is configured to generate a signal that activates the rotation device.
