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 fault notification system comprises a plurality of tower sensor units and a central processing element. Each tower sensor unit includes a tower safety sensor and a tower processing element. The tower safety sensor monitors a rotation angle of a mobile tower and output a signal that varies according to the rotation angle. The tower processing element is configured to receive the signal, compare a signal level of the signal with a range of signal levels indicating a normal rotation angle, and transmit a message that a fault has occurred and request that each drive motor shut down if the level of the signal is out of the range indicating a normal rotation angle. The central processing element is configured to receive the message from the tower processing element and transmit a signal to each tower processing element to output a signal to instruct each drive motor to shut down.
