Abstract: A control system for monitoring a motor and wheel drive gearbox of an irrigation system drive train. The control system includes a motor sensor for sensing an operating state of the motor and a gearbox sensor for sensing an operating state of the wheel drive gearbox. If the motor operating state exceeds a motor operating state threshold or changes too quickly, or if the wheel drive gearbox operating state exceeds a wheel drive gearbox operating state threshold or changes too quickly, the control system operates the drive train at a reduced capacity or in a modified mode such that the operating state is not exceeded or does not change too quickly.

Abstract: 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.
