Abstract: A volumetric meter having a roller configured for rotation within a housing aperture of a roller housing. A plurality of chambers of the roller are used for metering an agricultural commodity, each chamber being defined by at least a pair of flutes. In controlling an amount or height of the commodity displaced from an inlet of the roller housing and into the housing aperture with the rotation of the roller, the volumetric meter can include a sweep assembly having a sweep body that includes a compliant sweeper portion. As the roller rotates, the compliant sweeper portion can be configured to be displaced, including deformed, bent, or deflected, by a force exerted on the sweeper portion by agricultural commodity while still providing a barrier to a displacement of at least some commodity into the housing aperture to assist in preventing commodity from becoming wedged between the flutes and the roller housing.

Abstract: A self-aligning and self-engaging drive coupling on a seeding machine planting unit allows for one drive or driven device of the planting unit to be moved between a use position and a service position without the need to manually connect or disconnect the drive coupling between the two devices.
