A grain distribution apparatus and method is disclosed for positive positional control of the providing distribution of grain among a plurality of receiving ducts. A housing contains a distribution spout rotated by a drive motor among discharge positions at each receiving duct. A control wheel connected to the spout rotates with the spout to a selected discharge position. The control wheel has a plurality of sensible code clusters and position proof windows, one of each for each discharge position. Each code cluster has a unique series of data digits and a series of sequencing digits adjacent the data digits. The data digits and sequencing digits are serially read by a sensor. The sensor is connected to a control processor for identifying the position of the spout. The control wheel is configured as a driven sprocket and is engaged by the upper portion of a double wide roller chain around the entire periphery of the control wheel. A planetary driver sprocket connected to a drive motor is engaged with the lower portion of the roller chain. The drive motor is controlled by the control processor. When a specific receiving portion is selected the control processor operates the drive motor until the sensor senses the code cluster corresponding to the selected receiving portion. After sensing said cluster the motor stops. The sensing of a position proof window at the sensor confirms the spout is properly position at a receiving portion.
