Abstract: A detachable coupler for a seed carrying conduit comprises a first male portion and a second female portion. The first male portion is provided with a circumferential latching engagement channel. One side of the channel is defined by a circumferential latching rim having an angled surface and a latching surface. The second portion is provided with at least two tongs. The tongs are provided with latches for engaging the latching channel. The second portion is also provided with a seed cut off comprising a sliding gate. The gate is slidably positioned in a slot formed in a tower integral with the second portion.

Abstract: A pneumatic coupler for an agricultural seeding machine comprises a hollow tube having an inner portion and an outer portion that are separated by a radially extending flange. The radially extending flange has an inner surface adjoining the inner portion and an outer surface adjoining the outer surface. A flexible and resilient gasket is fitted over the inner portion and adjoins the inner surface of the radially extending flange. The inner portion is further provided with radially extending catches that are located on resilient axially extending tongues formed in the inner portion. When mounted to receiving apertures the catches contact the interior side of the receiving aperture and the flexible and resilient gasket forms an air seal between the exterior surface of the receiving aperture and the inner surface of the radially extending flange.

Abstract: A product on demand delivery system directs product from a main hopper to an application unit. An air pump directs pressurized air to a plurality of air supply hoses. The air supply hoses are coupled to air inlets located on the nozzle assembly of the main hopper. Opposite the air inlets are corresponding product outlets for receiving the air streams and product entrained in the air stream. The product outlets are coupled to product supply hoses that are in turn coupled to auxiliary hoppers located on the application units. The corresponding air inlets and product outlets have baffles extending above the air inlet and outlets. Gaps are formed between adjacent baffles. An agitator assembly having radially extending fingers is located above the baffles. The radially extending fingers extend into the gaps formed by the adjacent baffles.

Abstract: A seeding machine having a wing frame with planting units. The planting units are coupled to the wing frame by a pivot arm. The pivot arms move the planting units between a horizontal working configuration and a vertical transport configuration. An operator walkway is located above the planting units. The operator walkway comprises a walkway frame and a footboard. The walkway frame is pivotally coupled to the wing frame segment by a walkway frame pin. The footboard is pivotally coupled to the walkway frame by a footboard pin. As the planting units are moved from their horizontal working configuration to their vertical transport configuration the walkway frame and attached footboard are automatically folded between the planting units and the respective wing frame segment.

Abstract: An air seeder is provided with a pneumatic distribution system for delivering product through a plurality of primary tubes arranged in first and second rows. The pneumatic distribution system has a plenum housing having a plurality of outlet ports also arranged in first and second rows, each of said plurality of outlet ports associated with one of the primary tubes. A fan is in fluid communication with the upstream end of the plenum housing. A damper is mounted in the plenum housing upstream from the outlet ports for directing the air flow toward at least one of the first and second rows of primary tubes, and a perforated baffle plate is mounted in the housing between the damper and the outlet ports. The baffle plate has a plurality of openings adapted for governing the airflow into the outlet ports.
