A sectional meter shut-off apparatus for use in preventing material such as seed or fertilizer from reaching a metering device, for the purpose of preventing double seeding or double fertilizing. The sectional meter shut-off apparatus comprises a plurality of gates capable of opening or closing access to a metering roller. The plurality of gates can be controlled through electric actuators, hydraulic cylinders or a shaft. These gates can individually be controlled through an electric switch connected to the cab of the vehicle and operated by the driver, or automatically controlled by a GPS/GNSS system capable of determining which areas of the field have been previously seeded or fertilized. Additionally, an agricultural implement is further provided, comprising a dual material dispensing apparatus, which incorporates a meter shut-off device, and hydraulic rams to raise ground-engaging soil openers when passing over soil that has been previously seeded/fertilized.

An air seeder distribution apparatus has seed and fertilizer tanks, and a like plurality of metering devices mounted on each product tank. A manifold set comprises a like plurality of product manifolds and each manifold is separately fed from one metering device on each of the seed and fertilizer tanks. A control selectively starts and stops rotation of the feed roller of each metering device to feed product from either tank, or both tanks to the connected manifold. The weight of each tank can be displayed on a weight indicator. Balancing of the pressure in each supply conduit can be provided. A remote opener exerts downward force on the tank lid to maintain interior pressure.

An air distribution apparatus has a manifold body, and ports defined through walls thereof, with a delivery conduit connected to each port. A port valve is configured to connect and disconnect the delivery conduit to the interior of the manifold body. A supply conduit delivers a product air stream with agricultural products entrained therein to the interior of the manifold body. The supply conduit extends vertically up from the manifold to a curved elbow and then extends horizontally from the elbow. An exhaust orifice is defined in the inner radius of the elbow. When an exhaust valve is open, a selected flow of pressurized air flows from the supply conduit through the exhaust orifice. The port valve and exhaust valve are controlled such that when the port valve closes, the exhaust valve opens. The exhaust air can be directed into the delivery conduits to clear product therefrom.

An air velocity indicator and control device is provided for use with pneumatic distribution systems used in air seeders that pneumatically discharge agricultural product to the ground, seedbed, or furrow. The air velocity indicator and control device includes a tubular housing, extending between an inlet and an outlet, and pivotally housing a deflectable plate that actuates in response to encountering an airflow entrained with agricultural product. A magnitude of deflection of the deflectable plate, corresponding to airflow velocity, can be displayed through an indicator assembly. This enables a user to identify velocity variances and differentials within the air seeder and make corrective adjustments. In some implementations, multiple air velocity indicator and control devices are ganged together with deflectable plates that pivot in unison with each other. The relative angle of fixation of the deflectable plates, upon the pivot pin, can be adjusted to permit airflow tuning as needed.

According to an existing seedling transplanter, a rotor used for right and left leveling earth surfaces and a rotor used for centrally leveling earth surface are mounted respectively at a seedling planting mechanism to constitute a complicated structure wherein the rotors for leveling earth surfaces are very heavy, then the seedling planting constructional properties for agricultural land task become worse. The seedling transplanter in accordance with the present invention, in which a seedling planting part is mounted at back side of a walking car body equipped with right and left back wheels by aid of an elevation and subsidence connecting rod mechanism, is characterized in that a central earth surface leveling task mechanism is mounted at the seedling planting part, which locates in front of the central floating body between the right and left back wheels and between the right and left back wheels at the bolt body in the confrontation; a right and left earth surface leveling task mechanism is mounted at back of the right and left back wheesl or in front of the outer side floating body, which locates at back of the right and left back wheels at the bolt body in side-glance. The central earth surface leveling task mechanism is configured more upwards than the right and left earth surface leveling task mechanism, at the same time, the central earth surface leveling task mechanism and the right and left earth surface leveling task mechanism are connected integrally into an integral structure and are set to be capable of freely regulating the up and down positions.
