Abstract
A method of autonomously controlling the ground speed of a harvester, such as a self-propelled or towed wind rower, uses both the engine speed and the header speed as control parameters to increase or decrease the ground speed as necessary to maintain efficient harvester operation over varying terrain and crop conditions. A control system includes a controller which receives signals from sensors indicative of engine speed, header speed and harvester ground speed and uses actuators to control the header speed, engine speed and harvester ground speed. An operator interface permits an operator to engage or disengage the autonomous mode of control system operation, as well as to directly control the harvester.
