Problems cleaning up after cows on Chellington V2

[Omniplasma]

I tried posting this in the chellington feedback thread but it was closed. I've been experiencing problems cleaning up after cows on Chellington, the chaff or whatever it is gets inside the feed bunk and you can't get it up with a roller or brush. I get it to the point where I don't see any more green on the ground but cleanliness won't reach 100% because of the bits I can't reach. I play on Xbox One.
