Abstract
An air seeder is provided with a control system for controlling the velocity of air flowing though the product delivery tubes between the product storage tanks and the planting mechanism for delivering the product into the ground. A multiple tank air seeder would be provided with a bank of product delivery tubes for each product storage tank with an air damper mechanism incorporated into each respective bank of product delivery tubes. An electric actuator is mounted on the air cart to connect to each respective air damper mechanism and effect the movement thereof between a fully closed and a fully opened position and, thereby restrict the movement of air through the product delivery tubes. The control mechanism includes a control panel from which the electric actuators for the air damper mechanisms and an electric actuator for controlling the rotational speed of the fan creating the flow of air through the product delivery tubes can be controlled. The air velocity is controlled by setting a base fan speed through the control panel and then sequentially setting the rotational position of each respective air damper mechanism so that each bank of product delivery tubes can have a different resulting air velocity for proper delivery of the product, e.g. seed or fertilizer, through the respective product delivery tubes.
