Care of Plows.—Next in importance to having good tools to work with is the keeping of them in proper working trim. It is extremely wasteful to purchase good tools and convert them into poor ones by lack of care, and in no case do these remarks apply with greater force than to plows. The John Deere Co., in their catalogues, make some re- marks regarding the care of plow-shares, and through their kindness I am permitted to use some of their illus- trations. Figs. 56 and 57 represent a proper and an im- proper form of point. A dull point may increase the. Fig. 56. draft of a plow six to eight per cent, and more, besides necessitating poorer work. The tendency of wear on the point is to change it from the sharp, slightly dipping form represented in Fig. 56 to the blunt up-turned form shown in Fig. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original King, F[ranklin] H[iram], 1848- [from old catalog].
