A crop harvesting machine is equipped with a crop intake arrangement which delivers crop to a crop processing arrangement. In order to maintain a substantially constant, flow of crop to the crop processing arrangement despite a variance in the amount of crop, located in various locations on a field a control circuit employing non-, precise or fuzzy logic controls the forward propulsion speed of the harvesting machine and/or the speed of a, conveyor used to unload a buffer or crop accumulator that is mounted upstream from the, crop processing arrangement.

Why it's free to use
- Filed May 5, 2000 and granted April 8, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 5, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 5, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
