In the present study, a rota-cultivator; a passive-active combination tillage implement (cultivator in the front and rotavator in the rear) was designed and developed. Tillage performance of rota-cultivator and rotavator alone (pure active tillage implement) was evaluated in sandy clay loam soil at a moisture content of 11 ± 0.89 % (db) and compared in terms of tillage performance index (TPI) and soil compaction below the tillage depth by varying the peripheral to forward speed ratios and depth of operation during field tests. The power take off (PTO) torque requirement to operate the rota-cultivator was found to be 28 % lesser as compared to rotavator alone but an opposite trend was found for draft, total power and fuel consumption at all experimental conditions. For both the implements, overall performance was expressed in terms of TPI comprising volume of soil tilled, reduction in soil strength and fuel energy input. The highest TPI (1.62) was found at a velocity ratio of 5.87 and 120 mm depth of operation for rota-cultivator and it was found to be higher than the TPI of rotavator at all operating conditions. Soil compaction below the tillage depth due to tractor traffic with rota-cultivator was measured to be 27 % lesser as compared to rotavator alone. The developed rota-cultivator was successfully operated with a 34 kW two wheel-drive tractor in the test soil up to a depth of 120 mm, with improved tillage performance and reduction in soil compaction due to lesser number of passes required to obtain a desired titlth as compared to the rotavator alone.

在本研究中，轮式耕ator机；设计并开发了被动-主动组合耕作机具（前部耕cult机，后部旋耕机）。在含水量为11±0.89％（db）的砂质壤土中，对轮耕机和旋耕机（纯主动耕作机）的耕作性能进行了评估，并比较了耕作性能指数（TPI）和土壤压实度低于耕作性能。在田间试验期间通过改变外围与前进速度比和操作深度来改变耕作深度。发现与单独的旋转耕compared机相比，操作旋转耕ator耕机的取力（PTO）扭矩要求降低了28％，但在所有实验条件下的吃水，总动力和燃料消耗却发现了相反的趋势。对于这两种工具，总体性能用TPI表示，包括耕种的土壤量，土壤强度降低和燃料能量输入。旋转耕iv机的速度比为5.87，操作深度为120 mm时，TPI最高（1.62），并且在所有操作条件下均高于旋转耕of机的TPI。与单独使用旋转耕compared机相比，使用旋转耕cult机耕种耕tractor机耕作的耕作深度以下的土壤压实度降低了27％。研发的旋转耕种机在34 kW的两轮驱动拖拉机上成功地在120 mm的深度的土壤中运行，由于获得所需的滴定度所需的通过次数减少，从而提高了耕作性能并减少了土壤压实与单独的旋耕机相比。旋转耕iv机的速度比为5.87，操作深度为120 mm时，TPI最高（1.62），并且在所有操作条件下均高于旋转耕of机的TPI。与单独使用旋转耕compared机相比，使用旋转耕cult机耕种耕tractor机耕作的耕作深度以下的土壤压实度降低了27％。研发的旋转耕种机在34 kW的两轮驱动拖拉机上成功地在120 mm的深度的土壤中运行，由于获得所需的滴定度所需的通过次数减少，从而提高了耕作性能并减少了土壤压实与单独的旋翼机相比。旋转耕iv机的速度比为5.87，操作深度为120 mm时，TPI最高（1.62），并且在所有操作条件下均高于旋转耕of机的TPI。与单独使用旋转耕compared机相比，使用旋转耕cult机耕种耕tractor机耕作的耕作深度以下的土壤压实度降低了27％。研发的旋转耕种机在34 kW的两轮驱动拖拉机上成功地在120 mm的深度的土壤中运行，由于获得所需的滴定度所需的通过次数减少，从而提高了耕作性能并减少了土壤压实与单独的旋翼机相比。与单独使用旋转耕compared机相比，使用旋转耕cult机耕种耕tractor机耕作的耕作深度以下的土壤压实度降低了27％。研发的旋转耕种机在34 kW的两轮驱动拖拉机上成功地在120 mm的深度的土壤中运行，由于获得所需的滴定度所需的通过次数减少，从而提高了耕作性能并减少了土壤压实与单独的旋翼机相比。与单独使用旋转耕compared机相比，使用旋转耕iv机耕种耕tractor机耕作的耕作深度以下的土壤压实度降低了27％。研发的旋转耕种机在34 kW的两轮驱动拖拉机上成功地在120 mm的深度的土壤中运行，由于获得所需的滴定度所需的通过次数减少，从而提高了耕作性能并减少了土壤压实与单独的旋翼机相比。
