Abstract
A pneumatic seeder is provided, which is configured to be fixedly attached to a farming machine. The seeder includes an element for contacting with the ground, an element for storing a product to be sown, a pneumatic distributor of said product, a suction fan having at least one air inlet connected to the pneumatic for distributor and at least one air discharge outlet, an air extractor connected to the discharge outlet, the end of the air extractor leading out to face the ground. The seeder includes a damper and/or diverter for damping and/or diverting the flow of air coming from the air extractor. The damper and/or diverter is placed downstream from the end of the air extractor.
