PROBLEM TO BE SOLVED: To improve working efficiency by rationally placing a manual stretching means which performs stretching operation in a stretching device, a manual turning means which performs turning operation in a turning device, a manual lifting means which performs lifting operation in a lifting device and the like. SOLUTION: A grain-discharging apparatus is constructed as follows: when automatic operation means are actuated, a discharge auger 20 can move either to a storing position or to a working position through automatic lifting and automatic turning with a lift operating means and a turning means; when a manual length-changing means is actuated after the operation of the automatic operation means, the length-changing means works until the length of the auger 20 becomes detectable by a length detection means so that the length of the auger 20 can be changed; and further, while the discharge auger 20 moves from a position other than the storing position to the storing position, the length- changing means is actuated so that the length of the discharge auger 20 is automatically changed to the shortest one which can be detected by the length- detection means.
