ABSTRACT:
Each opener of a seed planting machine may be essentially tool-free equipped with a selected one of two or more types of interchangeable singulating meters. Each type of meter is mounted on its own adapter plate to present a module that has quick-attach mounting projections arranged and configured in an identical manner to all other modules. The projections fit into mating slots on an upright member of the opener, and the upper projection of each pair is in the nature of a downturned hook that facilitates hanging the module on the opener while also retaining it against fore-and-aft displacement. A stabilizing clip at the rear of the module securely receives the lower, rear edge of the adapter plate, and an over-center toggle latch securely retains the plate within the stabilizing clip to complete the solid yet readily removable attachment of the meter to the opener. A chain drive assembly for the meter is permanently installed on the opener so as to not be removed therefrom during interchanging of the meters. A support plate for the drive assembly is normally close to the meter in an operating position but can be swung outwardly to a release position when a latch between the support plate and the metering module is released, thus disengaging the drive assembly from the meter and providing clearance for the metering module to be lifted and removed from the opener.
