Abstract
A wear insert is provided for an air seeder metering system directing rising air away from product as it is metered from a product tank by the associated metering system. The wear insert has a lip which extends into the outlet of the metering system in order to divert air away from the path of metered product to prevent the product from bunching and to promote a continuous flow of product from the metering system.
