    A combine harvester incorporating an automatic travelling speed control system is adapted to reduce its travelling speed with an increase in the threshing load. The travel speed control includes a unit for detecting the output speed of a first speed change unit 10 before the output is subjected to a speed change by a second speed change unit 11. The first speed change unit is preferably an hydraulic stepless speed change unit whose control linkage is automatically adjusted by an electric motor 23 when the torque changes. Electric transducers are used to provide signals of torque and speed. <IMAGE>
