ABSTRACT OF THE DISCLOSURE Apparatus for controlling the forward speed of operation of a combine harvester to either increase or decrease the speed, characterized by means for sensing the density of the output from the harvester and producing a first electrical signal one parameter of which varies with the variation in density of the harvester output, means for producing a second electrical signal the same parameter of which varies with variation in speed of operation of the . drive for the harvesting apparatus, means for comparing the two electrical signals to produce a difference signal the magnitude and polarity of which indicate the relationship between the two generated electrical signals and means is provided for controlling the speed of operation of the drive producing forward movement of the harvester in a manner so as to cause the difference signal to be reduced to a minimum. `:
