One nice feature of my garden cart, is the tub is removable.A couple inches of Oats still in the soft outer husks are put in the tub, and moved to be on the ground. Now by walking or even dancing on the oats, the soft outer husks are loosened from the grain. When we get a windy day, the they can be poured out several feet above a clean tarp, and the breeze will carry away the chaff.
