The side-shift offset rotavator was a newly introduced implement in the field of inter-culture operations, especially for the orchard crop. The commercially available implement was equipped with J shape soil cutting blades. Those blades were replaced with L shape blades due to their undesirable outcomes. The testing was carried out separately for both types of blades at a fixed tilling depth of 9.6 cm. In this study, the type of cutting blade, kinematic parameter and soil moisture were the considered as the explanatory parameters. Whereas, the mean weight diameter of soil, weeding efficiency, fuel consumption, theoretical torque, and cost of operation were taken as response parameters. The results revealed that the L shape blade produced finer soil than the J shape blade for the same kinematic parameter and soil moisture with the higher torque and fuel consumption. Considering the optimized value of the above parameters, the effective field capacity and cost of operation were determined as 0.12 ha/h and680 ₹/h, respectively.
