Optimal design and analysis of oscillatory mechanism for agricultural tillage operation

The paper presents to design a vibratory mechanism for agricultural tillage operation. Agriculture tillage plays an important role for crop cultivation. There are different unit farm operations. Tillage is the mechanical manipulation of soil to obtain suitable soil condition for seed germination and growth. There are two basic soil manipulation processes such as primary and secondary. Draft consumption plays a vital role while performing the operations. Vibratory tillage concept was introduced since 1955 which results in low draft consumption. Tools oscillate in a particular mode of oscillation with certain amplitude and frequency along with the implement forward motion. The objective of the paper is to design an optimal four-bar mechanism for vibratory agricultural tillage operation to trace the desired experimental trajectory by the tillage tool in the field.
