PROBLEM TO BE SOLVED: To provide a harvester which can operate crop-conveying means (grain straw-conveying device) at a speed suitable for the properties or the like of crops in a field so that the conveyance performance of the crop-conveying means is improved. SOLUTION: The harvester including a travel machine frame equipped with traveling portions operated by an engine 14, the reaping blade device for cutting the foots of crops planted and standing in field, and crop-conveying means for conveying the crops from which the foots are cut off by the reaping blade device, includes: a conveying-driving electric motor 92 for operating the crop-conveying means; a rotation sensor 288 for detecting the number of rotations inputted to the reaping blade device or the like; and a conveying speed-setting device 262 capable of changing the number of the rotations of the conveying-driving electric motor 92, wherein the conveying speed-setting device 262 is manually operated by an operator, to change the outputted rotations of the conveying-driving electric motor 92 for adjusting the conveying speed of the crop-conveying means, while the number of rotations of the conveying-driving electric motor 92 is controlled on the basis of the detection result of the rotation sensor 288.
