The expanded metal was left over from this deal.

The baskets stay in the fill ports all the time and act as a filter so nothing bigger than what will run through the metering roller can get in the tank. Seed wheat or 46-0-0 runs through them like water. This transfer auger will mostly be used for getting fertilizer out of the delivery semis into my storage bin. The guard won't keep a determined fool from hurting himself on the flighting, but it will at least give a guy a chance if he accidently puts a hand where it doesn't belong or trips and falls into the hopper. I don't think it will have much of a filtering effect here as the 2 inch slot at the bottom will let most things through.
