Abstract: A unitary assembly has a housing for enclosing a drive, the housing including a handle, a cylindrical distribution chamber with a vertical axis and a slot directed away from the handle. A motor is mounted below the distribution chamber to rotate a rotor within the chamber, the rotor having vanes spaced from the center of the rotor. A hopper is removably mounted to the top of the distribution chamber. A control means is provided on the handle adjacent the side toward the distribution chamber for controlling the motor, and for controlling the flow of particulate material from the hopper into the distribution chamber.
