“…This enabled the shanks to provide more cracks, taking into consideration the increasing disturbance. The increasing response of disturbed area observed with operating depth is in agreement with McKyes and Maswaure (1997), Al-Suhaibani andGhaly (2010), andRamadan (2011).…”

“…In sandy loam soil conditions kichler et al (2008) found that a KMC Generation I Rip-Strip subsoiler operating at 13-14 Inches depth required 7.295 Ibs at 1.8 m h -1 forward speed and 10.017 Ibs at 5.0 m h -1 forward speed. The effects of operating depth on disturbed area were reported by McKyes and Maswaure (1997). They found that disturbed area increased from 0.0207 to 0.0427 m 2 by increasing the depth from 10 to 20 cm in clayey soil.…”

The objectives of this investigation were to investigate the effects of plowing depths (D) (35, 45, 55, and 65 cm), forward speeds (S) (0.341, 0.551 and 0.761 m sec -1 ) and outfitted subsoiler foot with wings on equipment performance for two subsoiler shanks arrangement (oblique and parallel) in silty clay loam soil. A significant (p<0.01) decrease in draft and specific resistance were observed for oblique shank arrangement compared with parallel shank arrangement. Furthermore, the draft and disturbed area increased significantly (p<0.01) with increasing operating depth, whereas specific resistance decreased significantly (p<0.01) with depth for the oblique and parallel shanks arrangement respectively. The values of draft, disturbed area and specific resistance of the oblique and parallel shanks arrangement tested were affected significantly (p<0.01) by adding wings to subsoiler feet. Forward speeds had a significant (p<0.01) effect on studded parameters. The optimal performance were found with the forward speed of 0.341 m sec -1 .

“…Similar data were obtained by foreign researchers [10][11][12][13][14][15][16]. These works establish the work tool parameters to provide better soil pulverization at minimal draught resistance of the work tools [11]; they also study energy consumption by different crop production technologies and method for tractor draught class selection according to the tillage technology [12], develop an approach to justification of the design of tillage machines to provide their reliability [13], study the effect of work tool type, tillage depth and velocity on productivity of tillage machines on clay soils and necessitate their alignment [14], investigate the impact of tillage depth and velocity on draught resistance when working with different types of work tools [15,16].…”

Annotation-The crop capacity in different soil and climatic zones depends on implemented technologies of tillage and sowing, crop rotation and type of work tools of the machinery complex. In every zone, main and additional tilling should be made with different work tool types and to different depth corresponding to the zone conditions. The tillage should also provide conditions for plant growth and development, as well as accumulation and rational usage of accumulated moisture during the whole vegetation period. The work demonstrates that tillage by foreign machinery not tailored to Russian conditions as compared to locally produced machines withers the soil away, reduces crop capacity and increases the base costs. In this connection, the team of researchers has elaborated a universal technology for soil treatment and types of work tools for machines to put it into life. Having said that, the type and dimensions of farms dictates the degree of universalization of newly created machines, so they should have replaceable working elements or interchangeable modules. The methods for determining the metal consumption for machines of different type, their draught resistance and performance of equipment were developed; the calculations are also presented. The study yields dependencies that allow establishing adequate velocities of equipment and operating width of tilling and sowing machines that ensure maximum performance of equipment with tractors having different draught class. The parameters of machines are used by the engineers of LLC Chelyabinsk Compressor Plant, LLC Varnaagromash and Yaroslavovich Production Company for designing and putting into production a complex of tillage and sowing machinery for tractors of draught class 1,4; 3; 5 and 6-7. The developed complex of machines performs all components of tillage technologies for specific working conditions and corresponds to functional specifications of agricultural machinery, environment protection, ergonomics and energy saving. Thus, the developed import-substitution technology and complex of machines enable increased crop capacity and reduced base cost of cultivated crops, which is the basis for liquidation of food dependence of Russia.

“…Then for each cross section the area of original soil cut (A o ) and the resulting total area of disturbed soil (A f ) were estimated by plotting the measured coordinates of the cross sections areas using the Sigma Scan Pro5 computer package. Soil loosening values were found using the following formula [16];…”
