Abstract
Apparatus for controlling the speed of a combine harvester () includes one or more sensors () each generating one or more signals that correspond during use of the combine harvester to variables of a harvesting process. The apparatus further includes a processor and one or more control devices operatively connected in a feedback arrangement including two loops. In a first loop, a first signal () corresponding to the ground speed of the combine harvester () is fed back as an input to a first control device () that is capable of adjusting the ground speed relative to a set value. In a second loop, the first signal () is fed together with a second signal () indicative of the flow rate of crop through the combine harvester to a second control device () that generates as a third signal () the set value, the third signal being input to the first control device ().
