METHOD TO DECREASE SEPARATION LOSSES AT THE HARVEST OF GRAINS AND ADVANCE SPEED REGULATING DEVICE OF A HARVESTER TO DECREASE SEPARATION LOSSES

摘要

A method and device to decrease separation losses in a harvester, wherein grain separation losses or harvest yield are detected and controlled changes are introduced to the advance speed of the harvester in a way that can be previously defined by the producer without overriding the contribution of the operator driving the machine. Instead of connecting the accelerator cable (37) to the accelerator pedal (25), it is physically connected to an electrical motor (31). On the other hand, the pedal is connected to a positioning sensor (29) that is read by a processor (43), which delivers a control signal to the electric motor to control the fuel passage to optimize the harvester advance speed (11), seeking for the best balance between separation losses and harvest time.
