Design and Performance Evaluation of Mechanical Weeder

Soil tillage, crop production, and animal husbandry are all part of agriculture. Weed management with herbicides and tractors is only possible if the plants are seeded in straight and parallel rows, as weeds grow between them. It is critical to prepare the field before planting in order to achieve optimal outcomes. Manual labour necessitates a large workforce and accounts for roughly 25% of overall labour demand, which is typically 900-1200 M hours per hectare. By breaking the surface crust, aerating the soil, encouraging the microflora of the soil, minimizing soil moisture evaporation, and promoting infiltration of rainwater, mechanical control of the grass successfully prevents weeds and promotes cultivation. To cultivate using a cultivator mechanically. Following these issues, a multi-stage weeder was designed and constructed in Creo 2.0 software for multi-stage weed treatment. The performance of this newly created equipment was tested both in the lab and in the field. The field capacity was 0.30 ha/h, and the field efficiency was 83.06 percent at a speed of 1.36 km/h. At a wheel slippage of 4.62 percent, the multi-stage weeding efficiency was 80.47 percent for single pass and 68.26 percent for double pass.
