In one embodiment, an air seeder tower includes a valve with an actuator, and a closed loop feedback control with a sensor to control actuation of the valve to control air flow out of the air seeder vent tower.

Air seeders that have force actuators acting on the firming implement and/or the closing wheel to adjust the downforce. In one example, the seeding implement includes a support arm having first and second portions. A finning implement support arm is pivotally connected to the support arm second portion at a first pivot at a first end of the finning implement support arm. A firming implement force actuator is pivotally connected to the support arm second portion at a first end of the firming implement force actuator and connected to the firming implement support arm at the second end of the firming implement force actuator.

A collector/distribution assembly is provided for use with a product supply tank having a bottom outlet, comprising a housing having a front wall, a back wall and two side walls, said housing having an open top for receiving product from the bottom outlet of the product supply tank, an open bottom and at least one pair of side by side loading zones comprising a left loading zone and a right loading zone; a number of left pneumatic conveying lines for receiving air, each left pneumatic conveying line operably associated with a corresponding left loading zone to allow air to pass into, through and out of the left loading zone; a number of right to pneumatic conveying lines for receiving air, each right pneumatic conveying line operably associated with a corresponding right loading zone to allow air to pass into, through and out of the right loading zone; and at least one air stream selector device comprising a shaped diverter operable to be positioned at the bottom of the housing; whereby when the at least one air stream selector device is positioned at the bottom of the housing, the device closes off either the right loading zone or the left loading zone of one pair of side by side loading zones thereby diverting product to the other of the right loading zone or the left loading zone.

A seed planting apparatus for planting seeds and performing other agricultural processes includes a chassis, one or more rear wheels coupled to a rear end of the chassis, a seat coupled to the rear end of the chassis, and an air propulsion apparatus and a storage container that are positioned behind the seat. A frame is coupled to the chassis, a plurality of hollow members are coupled to the frame, and a seed metering apparatus is coupled to the plurality of hollow members, arranged so that the seed metering apparatus is in communication with the air propulsion apparatus.

A product distribution system for an air seeder includes a plurality of furrow openers and a plurality of product distributors mounted on an implement frame. Each product distributor comprises a seed container and a plurality of seed delivery conduits extending radially outward from the seed container A seed meter apparatus is connected to receive the seed product from the seed container and operative to meter seeds of the seed product into each of the seed delivery conduits. A seed product dispenser is operative to convey a seed product from a seed product tank into each seed container, and is operative to maintain a level of the seed product in each seed container above a selected level. The product distributors are spaced across the width of the implement frame.

An air distribution apparatus including a manifold body having ports with a delivery conduit connected to each port. A port valve is configured to communicate an interior of the manifold body with the delivery conduit associated with each port. A supply conduit is connected at an output end thereof to the interior of the manifold body and connected at an input end thereof to receive a product air stream with entrained agricultural products. An exhaust orifice is defined in the supply conduit and an exhaust valve configured to control a flow of pressurized air from an interior of the supply conduit through the exhaust orifice. The port valve and exhaust valve are controlled to operate oppositely to each other between their open and closed positions. The port and exhaust valves are also adjustable to intermediate positions between the open and closed positions.

A covering soil mulching apparatus according to an embodiment includes a soil scattering part at the rear end of the agricultural machine and including a scattering part frame and a scattering unit provided on a lower end side of the scattering part frame and scattering soil on a floor, a mulching film laying part including a laying part frame connected to a rear end side of the soil scattering part and a mulching film holding part having a mulching film wound around the mulching film holding part and spreading the mulching film on the floor, an oscillating plate above the mulching film holding part and guiding the scattered soil to be transported to a rear side and laid on an upper surface of the mulching film, and a soil oscillating part including oscillator for oscillating the oscillating plate to prevent formation of a soil wall on the oscillating plate.

An air seeding system and method includes a manifold mounted across a plurality of row planter units. Electric motors are mounted on the manifold and are operatively connected to the seed meters. A microprocessor or controller adjusts the speed of the motors in response to field data input so as to adjust the rate of seed dispensement to achieve desired plant population. The motor speeds can be adjusted on the fly, without stopping the air seeder. The system senses ground speed, senses the raised and lowered positioned of the row planter units, and senses any blockage of the row planter units. The motors eliminate the need for a ground drive wheel.

A seed cart coupler system for providing efficient connection of air seeder hoses between a seed cart and air seeder with a corrosion resistant coupler. The seed cart coupler system generally includes a first connector adapted to be removably connected to a second connector. The first connector includes a plurality of tubes that fluidly connect to corresponding seed hoses of a seed cart and the second connector includes a plurality of tubes that fluidly connect to corresponding seed hoses of an air seeder. The first connector and the second connector fluidly connect the seed tubes of the seed cart and the air seeder when connected together. The first connector and the second connector are preferably constructed of a material that is not corroded by fertilizer.
