Prediction of Power Consumed By Forward and Reverse Rotation Rotavator using Field Load Analysis

In this study, we installed forward and reverse rotation rotavators on a tractor to measure the load in thefield and analyze the power consumed. The rotavator is attached to the rear of the tractor and transmits thepower applied from the power take off (PTO) of the tractor to the rotating shaft of the rotavator, and it plowsor reverses the soil according to the rotational direction of the rotating shaft. Depending on the rotationaldirection of the rotavator, the power consumed in the tractor engine and the power transmitted to the tractoraxle and rotavator also vary, thus, research of load and power is an essential factor in designing the system. Asa field test results, 84.1–93.5% power was consumed by the forward rotation rotavator, and 37.8–57.5% powerwas consumed by the reverse rotation rotavator. In addition, depending on the rotation direction of the rotavator,the power consumed by the tractor was in the order of PTO and axle. Based on the research results,development of reliable rotavator systems would be possible in the future research.N
