Deere uses its nous as cheaper sprayer-boom control unveiled
the combine. The firm's MultiThresh system alters the aggressiveness of the rotary separator to suit the crop variety or moisture.
For example, in wetter conditions it is operated on an aggressive setting to aid removing all the grain.
The adjustment is set less aggressively in dry straw conditions to retain quality.
Coping with undulating or hilly ground are New Holland's SmartSieve and Opti-Fan systems. The SmartSieve system automatically changes the throw angle of the grain on the sieve to prevent build-ups of grain and straw, which are a key cause of poor grain samples or grain losses.
