When the seed is to be flailed, the crop ordinarily is cut with a scythe or mowing machine and the plants raked into piles or windrows. If only small areas are to be harvested in this manner, a canvas or tarpaulin may be spread on the ground beside a windrow or pile and several forkfuls of sweet clover pitched on the canvas, where the seed may be removed from the plants by striking them a few times with flails, sticks, or forks. After the plants have been struck a few times they should be turned over and struck again. When the seed is removed front the plants, the straw may be pitched to one side, the canvas placed beside another portion of the windrow or by another pile, and the operation repeated. It is not necessary to remove the seed from the canvas until its weight or bulk interferes with moving the canvas. It is the practice in some sections of the country to place a well-braced frame, covered with wire netting, on a sled and to flail the seed on this frame. The netting used for covering the frame should have meshes 1 inch or loss in diameter. The sled should be at least 7 feet wide and 10 feet long and should have sides and ends approximately 12 inches high. Smaller sleds sometimes are used, but a larger one is to be preferred if two or more persons are to flail on it at one time. If the floor of the sled is not perfectly tight, it should be covered with canvas and the edges of the canvas thrown over the sides and ends of the sled, so as to avoid losing any of the seed and to facilitate its removal. A sled so equipped may be drawn from pile to pile, the plants pitched on it, the seed flailed from them, and the straw returned to the land for soil improvement. Another method, very similar to that just described, is to place a frame on a hayrack. The frame should be built sufficiently strong and in such a manner that the person who is to do the flailing may stand on it. It should be covered preferably with galvanized-wire netting having half-inch meshes, and if this is stretched tightly it will serve to strengthen the frame. If it is not practicable to make the hayrack perfectly tight, it should be covered with a tarpaulin or canvas. A wagon so equipped may be pulled from pile to pile or along the windrows, where one person may pitch the plants upon the frame, to be flailed by one or more persons standing on it. After the seed is removed from the plants, the straw may be scattered easily and quickly over the ground for soil improvement.
