ABSTRACT OF THE DISCLOSURE An improved device for discharging particulate material, such as agricultural seed at a uniform rate comprises a hopper having a rectangular slot in the base, a driven roller covered with sponge neoprene which contacts one side of the slot and a glass metering plate attached to the hopper and which bears against the roller to provide a nip therebetween and to control the rate of flow of the material from the hopper. The device may be conveniently attached to an agricultural drilling machine and the roller driven by means associated with the ground wheels of the machine. Means are provided for directing the seed from beneath the roller into the seed drills. Seed is discharged into the drills at a constant rate and no adjustment is necessary for use with seeds of different sizes.
