Figure 1 shows a homemade device known in different sections as a plank drag, float, planker, clod crusher or slicker. It is valuable both as a pulverizer and a leveler. Drags differ greatly in size and style of construction. Whatever the form of construction the principles involved are the same. The drag is not so essential if the Meeker smoothing harrow is available, but in the absence of this tool it cannot be dispensed with. It is especially valuable in preparing a very fine, smooth surface for small seeds or delicate plants.
