PROBLEM TO BE SOLVED: To provide a granular material-discharging machine such as seeder in which discharge amount of a granular material per unit area is controlled so as to become constant by controlling the discharge amount of the granular material connected with a traveling speed of the seeder. SOLUTION: The granular material-discharging machine is equipped with a granular material-discharging apparatus 6 in which discharge operation rate of granular material installed on a traveling vehicle body 2 is variable according to the vehicle speed, a gear shift tool 24 for changing advancing speed of the traveling vehicle body 2. a vehicle speed sensor for detecting advancing speed of the traveling vehicle body 2, a belt conveyer lever position sensor for detecting operation position of the gear shift operation tool 24, a controller for controlling granular material discharge operating speed of the granular material-discharging apparatus 6 so as to make the granular material discharge amount per unit area constant, based on detection values of the vehicle speed sensor and the speed change operation position sensor and an alarm unit for sounding the alarm when the difference between the granular material discharge amount based on a detection value of the vehicle speed sensor obtained by the controller and granular material discharge amount based on the detection value of the speed change operation position sensor exceeds a prescribed value.
