The stationary housing is provided with an axially extending metering rim. The meter rim is provided with a metering gap. The stationary axially extending dispensing rim is located radially outward from the metering rim and is provided with a dispensing gap. The radially extending flange extends between the axially extending metering rim and the axially extending dispensing rim. The rotating disc is provided with an inner portion having circumferentially arranged seed pockets and an outer portion having seed dispensing openings. Each seed pocket corresponds to a seed dispensing opening. Passages extend between the seed pockets and the seed dispensing openings. The seed pockets of the inner portion are located adjacent to and radially inward from the metering rim.

An assembly for opening and closing a furrow in soil includes a furrow opener with a pair of discs positioned at an angle relative to each other. The discs each have an inner side facing toward each other and an outer side facing away from each other. Each disc also has a leading edge and a trailing edge relative to a travel direction. A furrow closer includes a pair of wheels, each having an inner side facing toward each other and positioned adjacent to a corresponding disc outer side. Each wheel also has a leading edge positioned between a corresponding disc leading edge and disc trailing edge, and a trailing edge positioned rearward of a corresponding disc trailing edge relative to the travel direction.

A seeding machine having at least one tool bar, a plurality of row units and a processing circuit. Each of the plurality of row units are connected to the toolbar. Each of the row units have a seed metering device, a seed placement device and a seed sensor. The seed metering device includes a seed disk providing a metering action to a plurality of seeds. The seed placement device receives the seeds from the seed metering device. The seed sensor is positioned to detect the passage of seeds through either the metering device or the seed placement device. The seed sensor producing a signal indicative of the passage of the seeds. The processing circuit is receptive of the signal from each of the seed sensors of each of the plurality of row units. The processing circuit determines a seed placement parameter dependent upon the signal, the processing circuit alters the metering action of the seeds dependent on the seed placement parameter.

A seed delivery apparatus has a moving member that captures and entraps the seed from the seed meter and physically moves the seed from the meter to the lower outlet opening. In so doing, the seed engages and travels along an interior surface of the seed delivery apparatus. A seed sensor is mounted on the housing wall such that the seed passes directly in front of the sensor. The sensor has both the light emitting devices and the photo-sensitive elements on the same wall of the delivery apparatus, or on two opposed walls. The moving member prevents ambient light, dust and dirt from entering the housing and impacting the sensor output signal.

A bushing is provided for mounting a pivot arm that has both a threaded portion as well as one or two smooth cylindrical portions. The threaded portion enables the pivot arm to be a laterally adjusted by rotating the bushing while the smooth portion or portions provide a bearing surface or surfaces for the pivot arm loads. This removes the load from the threads, reducing wear of both the bushing and the pivot arm, thereby reducing maintenance cost.

A ground working machine having a frame, a ground engaging wheel mounted to the frame and movable between a raised position not engaging the ground and a working position engaging the ground. The ground engaging wheel, when in the working position, rotating about a wheel axis as the machine is moved over the ground. An actuator raises and lowers the ground engaging wheels. A control system includes a sensor to detect rotation of the ground engaging wheel and a controller that receives an input from the sensor. The controller commands the actuator to raise the ground engaging wheel when the sensor detects that the ground engaging wheel is not rotating.
