PREPARING THE SEED BED The Plow the First Implement.—The first tool commonly used in the preparation of the seed bed is the plow. Because of its importance, it has been called the greatest tool in the advance- ment of agriculture. Long before the invention of the modern plow, tillers of the ground so fully realized the great necessity of some kind of implement to loosen the soil preparatory to planting. Fig 67 —Diagram illustrating the pulverizing action of the moldboard. (King ) that many of them used'a crooked, wooden stick. A modern moldboard plow is a comparatively plain tool and seems a simple invention, yet the history of its evolution reads like a romance. Because of its ingeniously devised steel moldboard, the modern plow can turn practically any kind of soil, and at the same time pulverize it more or less (Figs. 67 and 68). Certain equipment is required to increase the efficiency of the plow; such as, jointers and coulters, to cut sod into strips so it can be turned and to aid in turning under weeds, grass and htter; the gauge wheel, to aid in regulating the depth of plowing; and clevises, for draft adjustments (Figs. 69 to 74). Plowing Stubble Land.—Stubble land, or old ground, is land on which small grains and cultivated crops have been grown. Plows designed for such lands are called stubble plows. Their moldboards are short, high and have an abrupt turn. Because of.
