“…Table 2 and Figure 2 show the specifications and configurations of the test rotavators. 'C' shaped blades that require less power and torque compared to 'L' shaped blades (Beeny and Khoo, 1970;Salokhe et al, 1993) were used for the rotary-type rotavator.…”

“…There were several researches about rotary-type rotavator in the country (Lee et al, 2000;Lee et al, 2003;Myung and Lee, 2009) and internationally (Ghosh, 1967;Beeny and Khoo, 1970;Salokhe et al, 1993). They include a study of the effect of several parameters such as blade type, forward speed, number of passes, tillage depth and rotational speed of rotor shaft on operational characteristics like power or torque requirement.…”

Purpose: This study was conducted to understand the work performance of crank-type rotavators and compare them with those of rotary-type rotavators in Korean farmland conditions. Methods: Tillage operations were carried out using both rotavators with the same nominal rotavating width and rated power. During the operations, PTO speed and torque, actual work speed, and rotavating width and depth were measured. To evaluate work performance, pulverizing ratio, inversion ratio, and specific volumetric tilled soil were calculated and compared for each rotavator. Results: It is found that the crank-type rotavator has better specific volumetric tilled soil performance and deep tillage, while the pulverizing ratio is worse. Conclusions: Crank-type and rotary type rotavator have diffenent properties each other in several work performances. It's important, therefore, to choose a suitable type of rotavator that satisfy the farmer's requirements in accordance with the condition of field and the purpose of tillage operation.

Purpose: This study has been conducted to investigate the applicability of motion analysis of tillage blade for estimation of tillage characteristics of crank-type and rotary-type rotavators. Methods: The interrelation between tillage traces from motion analysis and field test results including rotavating depth, pulverizing ratio and inversion ratio at the same work conditions were analyzed for both crank-type and rotary-type rotavators. The work conditions include working speed of prime mover tractor and PTO speed of rotavators. For the motion analysis, joint conditions of main connecting component were specified considering the actual working mechanism of rotavator. Results: There were important correlations for the trend between motion analysis and field test results. Conclusions: Although further study is needed for applying motion analysis to estimate the accurate tillage related parameters such as rotavating depth, the soil pulverizing ratio and inversion ratio, it could be used to compare the tillage characteristics of various rotavators quickly and simply.

“…For seed bed preparation of rice, the quality of puddling is an important factor [3,4]. Many researchers have studied the effect of type, size, shape, orientation and speed of operation of power tiller tynes under flooded soil conditions with a view to optimize the blade parameters under field as well as controlled soil-bin conditions, [5][6][7][8][9][10][11][12][13][14]. Unfortunately, no systematic study so for has been carried out for optimization of blade parameters of a bullock drawn rotary puddler.…”
