SUBSOILER an implement for intermittent tillage at depths sufficient to shatter compacted subsurface layers. equipped with widely spaced shanks either in-line or staggered on a V-shaped frame (Figure 9). Subsoiling is commonly conducted with the shank paths corresponding to subsequent crop rows. Strong frame and shanks are required for deep operation. AENGR1105- BASIC FARM MACHINERIES, MECHANIZATION AND WATER MANAGEMENT  4. SUBSOILER They shatter, mix, and aerate the soil with little soil inversion and little coverage of plant residue. This helps prevent wind and water erosion but improve water penetration into the soil. AENGR1105- BASIC FARM MACHINERIES, MECHANIZATION AND WATER MANAGEMENT  5. ROTARY TILLER also called power tillers. Power is transferred to the tiller from the tractor via the power-take- off drive. A shaft containing blades is located at 90° to the line of travel and rotates in the same direction as the forward travel of the tractor. Since the shaft turns at a rate that is considerably faster than the corresponding tractor speed, soil pulverization is accomplished AENGR1105- BASIC FARM MACHINERIES, MECHANIZATION AND WATER MANAGEMENT  SECONDARY TILLAGE BREAK THE SOIL CLODS Secondary Tillage means stirring the F U SHATTER THE SOIL CLODS soil at comparatively shallow depths N LEVEL THE SOIL SURFACE follows the deeper C T HARROW THE SOIL AND primary tillage I PLANT WASTE (STUBBLES) it is possible to use some of the primary O FIRM THE SOIL tillage equipment to N do secondary tillage S KILL WEEDS AND HELP CONSERVE MOISTURE AENGR1105- BASIC FARM MACHINERIES, MECHANIZATION AND WATER MANAGEMENT  SECONDARY TILLAGE IMPLEMENTS SPIKE TOOTH HARROW can be tractor or animal-drawn till the soil to a shallower depth I DISC HARROW than primary tillage implements, M provide additional pulverization, FIELD CULTIVATOR P mix pesticides and fertilizers into L PACKER the soil, level, and firm the soil, E ROLLER HARROW close air pockets, M eradicate weeds.
