A machine a frame for mounting on a tractor, a drum with a filling opening in its sidewall closed by a movable shutter. A positioning device opens and closes the shutter by rotation of the drum about its axis. The positioning device may have a retainer at the free end of a lever mounted on the frame. The retainer selectively engages depressions in the shutter so it cannot move when the drum rotates. The shutter is mounted on two arms pivoting about the drum axis. Barbs at opposite ends of the shutter lock it in the open or closed positions.
