Smart Sieve™ and Opti-Fan™ really is smart
The Smart Sieve™ system automatically adjusts the sieve action to compensate for side slopes, increasing lateral movement to guide
the grain so it lies in an even layer across the sieve. The award-winning Opti-Fan™ system corrects fluctuations in the speed of grain
flow across the cleaning shoe. Whether working up-hill or down-hill, the fan speed automatically adapts to the direction and to the
degree of the slope, increasing overall cleaning efficiency by up to 30% in heavy conditions.
