Abstract
One or more techniques and/or systems are disclosed for metering assembly for an agricultural seeder. The metering assembly can be configured for quick and easy removal and replacement, where merely the assembly is removed without disassembling other parts of the seeder system. An improved coupler, in conjunction with a threaded knob device, allows for quick and easy access to the assembly, for removal and replacement in a metering tube. A visual indicator can be disposed on the end of a rotating shaft to provide a user with a quick confirmation that the assembly is properly rotating during operation.
