Development of a chisel plow draft force and power calculator based on some mechanical laws

Document Type : Research Paper

Abstract

The chisel plow is one of the tillage implements utilized to carry out conservation tillage practices; therefore, it is valuable to pay more attention on the force requirement of this implement. To achieve this goal, a theoretical model was developed to calculate draft, specific draft, and drawbar power of a chisel plow. Then, results obtained from the developed model were compared with the reports of other studies and the result of the field experiment in order to validate the developed model. According to the results, the required draft force of a twelve-shank chisel plow working at 30 cm depth in sandy, loamy, and clay soils were 27, 43 and 55 kN respectively and the required specific draft of this machine were 3.3, 5.1 and 6.5 N/cm2 respectively. These results were in accordance with the results of other studies, as well as the results of the ASABE standard (2011), therefore; the developed model is able to estimate draft force of the chisel plow acceptably.
