Design, Development, and Performance Evaluation of a Trash-Board Moldboard Plow for the Interaction between Soil and Straw with Two Different Water Content Levels

Abstract

Abstract:A two-year field study was conducted to investigate the performance of a lightweight trash-board moldboard plow (with and without a trash-board), as influenced by stubble height and water content. Both fields were measured for the performance of a trash-board moldboard plow when used during the optimization of the plowing depth, the water content, and the reaction forces. The results showed that in the first year, when a trash-board was required, the results were significantly different. The fields had lower draft and reaction force in the soil with only stubble height, which was greater than that in the soil with dense straw for all water content levels. This was also observed in the second year for the whole depth. This study shows that the moldboard plow with a trash-board provided minimum draft and reaction forces with only straw and heavy straw. The results indicate that straw nearby shear significantly increased displacement for all treatments, with variance of straw nearby moldboard. Hence, the results verify that a trash-board continuously created large soil fragmentation with different water content. Straw labels create a position of straw which also allows for better results. It is important to install trash-boards with the moldboard plow for heavy straw incorporation.

Modeling of Draft and Energy Requirements of a Moldboard Plow Using Artificial Neural Networks Based on Two Novel Variables

“…For crop planting, farmers usually prepare the soil using a primary tillage tool such as a moldboard plow (Abdallah et al, 2016). However, moldboard plowing ranks among the highest energy-consuming primary tillage operations (ASAE, 1992).…”

A Field Study of Soil Pulverization Energy by using Different Moldboards Types Under Various Operating Condition

“…The moldboard plow is one of the most important primary soil preparation equipment. moldboard plow can achieve all plowing goals through cut the soil and overturning it, which helps to pulverize the soil, thereby provide the suitable cradle for seed germination and growth, (Abdallah et al, 2016). The preparation of soil to agriculture and the provision of a suitable seedbed requires more than 60% of the energy consumed in all agricultural operations (Jacobs & Harrol, 1983).…”
