Application of MS Excel to Estimate Power Needs of Tillage Tools

Abstract This study deals with the application of the Microsoft Excel for the estimation of the power requirements of some tillage implements. The mathematical formulas embedded in the spreadsheet file have been developed in the previously published papers; however, those formulas were augmented her...
