A metering device having an obstruction within its metering chamber to prevent inputs such as seeds from passing from a seed sump to other areas within the metering chamber and causing to the metering device to become overfilled with seeds when the metering device is raised out of the planting position. In one embodiment, the obstruction includes one or more hingedly connected flaps that move due to the changing orientation of the metering device. In one or more positions of the metering device, the obstruction is positioned to prevent the seeds from leaving the seed sump. The seeds are prevented from leaving the seed sump without having to manually shut a gate on each metering devices of a planter.

An agricultural implement trailer for supporting one of a plurality of implements for field usage and transport. The trailer includes a trailer frame supported by transport wheels, and a turntable supporting a hitch member for attachment to a conventional three-point hitch connection on an implement. The hitch member is connected to a horizontally extending arm of the turntable through a linkage assembly including upper and lower link structures defining a parallelogram structure for moving the hitch member from a lowered field-use position to a raised transport position. In the raised transport position, the arm of the turntable supports an implement in cantilever relationship to a pivot member supporting the arm for pivotal movement. During pivotal movement of the arm, the supported implement is pivoted from an orientation with its long axis extending transverse to the longitudinal axis of the trailer to a position where the long axis of the implement is extending parallel to the longitudinal axis of the trailer. In moving the implement to its raised transport position, the center of gravity of the implement is moved forwardly of the pivot member, and the linkage assembly is moved to an over center position to provide a stable arrangement for supporting the implement and for pivoting it to its position longitudinally aligned with the axis of the trailer.
