We have developed this Productivity Calculator to help you understand the costs and benefits you might expect from a Kelly Diamond Harrow. By using information from your own farm, you can see the prodcutivity of the selected tools, including recommended horsepower, running costs and expected wear rate. We hope you find this informative.
