Optimization of the performance parameters of hoe type ridger under laboratory condition of vertisol (Black soil) by using response surface technique

Abstract

The goal of this study is to evaluate the performance parameters and their effects on horizontal force Fx (draft force), vertical force Fy (vertical reaction), and height of ridge for hoe type ridger during the operation in vertisol soil under controlled soil bin condition and optimize the best combination of width of cut, operational depth, and forward speed for hoe type ridger. All the fabrication work and experiments were completed in workshop and indoor soil bin laboratory of Department of Farm Machinery and Power Engineering, College of Agricultural Engineering, JNKVV, Jabalpur. After completing all experiments on the basis of Randomised Block Design (RBD) pattern and optimise the experimental data by using Box-Behnken Design (BBD) of Response Surface Method (RSM). The optimised solution from all experiments, we found a combination of all independent and dependent variables. The value of horizontal force Fx 1353.57 N, vertical force Fy 2731.21 N, and height of ridge 67.28 mm at 2.172 km/h forward speed, 40 cm width of cut, and 9.72 cm operational depth for the designed hoe type ridger.
