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.
