Abstract

The tea industry in South India faces significant challenges due to labour shortages and rising operational costs. Traditional manual harvesting and fuel-powered mechanical harvesters are increasingly unsustainable, prompting the adoption of lithium-ion battery-powered shear harvesters. These innovative tools offer enhanced efficiency, reduced environmental impact, and improved adaptability to diverse terrains. This paper explores recent advancements in battery-powered shears, their impact on tea harvesting efficiency, and their role in addressing labour shortages. Field surveys conducted by the UPASI Tea Research Foundation in Nilgiris and Vandiperiyar demonstrate a 40–50% increase in plucking averages compared to manual methods, with daily yields reaching up to 250–300 kg during peak seasons. The paper also discusses maintenance strategies, disease management, and challenges in adopting this technology, emphasizing its potential to transform tea cultivation into a more sustainable and profitable industry
