Helps to form a mulch and thus conserves moisture. Sod which is not plowed until spring, even though it is turned over as early as the weather permits, depends chiefly upon the disc for preparation. The firing of sod corn in July can usually be traced directly to spring plowing or an insufficient discing of fall plowing. Large pieces of turf admit the air and allow moisture to be taken di- rectly from the COMBINED PULVERIZER AND PACKER. Best adapted to grip clods and crush them. Special Harrows. For stony land, or in timbered sections where the teeth are liable to catch on roots, the spring-tooth harrow has a decided value. The teeth can be set to gouge forward and hence tear up sod more than the fixed tooth harrow. The later manufac- turers mount the frame on runners, which does away with bouncing effect common in spring-tooth harrows when set too deep. Some are also mounted on low trucks with the same end in view. Curved knife harrows and drag pulverizers are used to some extent, but where corn stalks are present in any number they ride over them too easily. For fining the surface of a field which has already been well worked, the pulverizer is especially well suited. Smoothing Harrow. The rigid, straight-toothed harrow does effi- cient work on ground free from trash. Because of an excess of stalks the slant tooth and lever harrows are more practical and 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 Bowman, Melville Le
