GRAVITY DEFYING OPTI-FAN™ TECHNOLOGY
The Opti-Fan™ system compensates for the gravitational effects on crop material during harvesting. Select the desired fan speed on flat ground and the system automatically adjusts it when going up or downhill to maintain cleaning performance. When travelling on upward slopes the fan slows down to prevent sieve losses, and when tackling downhill gradients fan speed increases to prevent thick material build ups on the sieves. This efficient system requires no extra work from the operator and provides a better grain sample together with reduced losses.
