I drag our large pasture with a cattle panel tied to a quadrunner.  It busts up the manure pretty good, but after a while you need to add weight to your drag.  I got a new lean-to this spring, and I have been using the manure/hay from our other lean-to to fill in the gap where they dug out for the new lean-to.  I don't know if this will work when the heavy rains come, but I figured they won't be standing in it, so why not use the manure mix for fill-in dirt.
