Mold-board and disk plows are used for this of these implements turn the soil, pulverize it and cover implement to be preferred is determined largely by the character ofthe soil and its condition. Disk plows work best in rather dry soil. Mold-board plows are much more extensively used and will work under a widerrange of soil conditions. The form of the mold-board plow varies con-siderably, and different forms are applicable to different purposes anddifferent soils. The sod plow has the minimum curvature and inverts 4 i 1 Miilte^. A Deep Tilling Double-Disk the furrow slice with the least pulverization of the soil. The stubble orbreaking plow has much more curvature of the mold board, and givesmore thorough pulverization of the soil. The greater the curvature ofthe mold board and the more thorough the pulverization of the soil as aresult of it, the heavier will be the draft. Sharpness of the share andsmoothness of the plow surface tend toward lightness of draft. Thepresence of roots and stones may somewhat increase the draft of texture, structure and physical condition of the soil, especially withreference to its water content, greatly influence draft.
