  • Patent number: 9215841
    Abstract: A particulate material delivery system for an agricultural implement including, an inductor box configured to receive particulate material from a tank, the inductor box including, an inductor segment comprising an air bypass channel extending through a particulate material supply chamber, wherein the particulate material supply chamber is configured to receive the particulate material for distribution to at least one row unit, and the air bypass channel is configured to guide airflow through the particulate material supply chamber without interacting with a flow of the particulate material through the particulate material supply chamber, and an airflow control device in communication with the inductor segment and configured to control the airflow through the air bypass channel.

  • Publication number: 20140311391
    Abstract: An agricultural machine for working soil or for sowing seeds, including a trailed chassis and work elements distributed on a longitudinal bar in plural sections, the longitudinal bar including at least two primary beams extending substantially transversely to a direction of advance in a work configuration. A secondary beam is connected to each primary beam by two connection devices, the secondary beams support the work elements, and each secondary beam rests on the soil by two support wheels and is configured to move freely during work to follow a profile of the terrain.

  • Publication number: 20120240835
    Abstract: A planting unit for depositing fertilizer and seed in a single pass, double shoot manner includes a rotating disc that cuts a furrow in a planting surface and a trailing seed boot, having a cutting edge, that cuts a vertically and horizontally offset trench in the furrow to form a seed bed in the planting surface. The disc has a mounting frame for mounting the disc to a linkage assembly that is, in turn, coupled to a toolbar mount. The seed boot is also attached to the mounting frame. This common attachment provides a relatively short and compact device without sacrificing fertilizer and seed stratification.
