A composted waste spreading (distributing) method and apparatus is disclosed. A storage hopper having a floor drag chain is employed to remove the composted material from the bottom of the hopper and push it out of the hopper through an opening. A unidirectional conveyor pushes the composted material into an air supplied airlock. The airlock has a flexible air conduit connected thereto for distributing the composted waste which is entrained into the airstream passing through the airlock under the force of a compressor. The airlock, conveyor and floor chain are driven by hydraulic motors and are either controlled manually or alternatively by an automatic controller.
