Abstract: 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.

Abstract: An air seeder includes a combination tank propulsion vehicle with mounted product tanks, and metering devices dispensing product from each product tank. A furrow opener implement is towed by the vehicle and an engine rotates the vehicle wheels and two or more implement wheels. A pneumatic distribution system conveys dispensed products to the furrow openers. The external guidance system sends location signals indicating a location of the implement frame to the operator. Steering, metering, and distribution signals are sent by both the external guidance system and an operator with a remote operator control, and operator signals override signals from the external guidance system.

Abstract: An agricultural commodity cart loading conveyor apparatus comprises a conveyor mounted to an agricultural commodity cart. A hopper is pivotally attached to the lower end of the conveyor tube and a hopper conveyor section is mounted along a bottom of the hopper. The hopper pivots from an extended position to a folded position. In the extended position the hopper is oriented at an angle to the conveyor tube such that the hopper extends along the ground when the conveyor is in the operating position, and is connected to the lower end of the conveyor tube such that the hopper conveyor section conveys material entering the hopper into the lower end of the conveyor tube for conveyance up the conveyor tube. A lock is operative to lock the hopper and conveyor together when the hopper is in the extended position. Hydraulic cylinders can be provided to facilitate use with larger conveyors.
