Modular farming attachment for integrated seeding, fertilizing, and weed removal in small-scale agriculture

Abstract
This project focuses on the design and development of a multipurpose machine for gardening and small-scale farming, integrating tilling, seeding, and fertilizer application into a single compact unit. The machine is powered by a 2-stroke 52CC petrol engine with a gear transmission system, making it lightweight, portable, and suitable for micro-farming and home gardening operations. The tilling unit consists of 16 rotary blades capable of preparing soil to a depth of approximately 1.5 inches, ensuring proper soil aeration and preparation for sowing. The attached seeder is adjustable for different row spacing’s and seed quantities, allowing uniform seed placement for various crops. Additionally, a fertilizer application unit is incorporated to distribute nutrients simultaneously, reducing the need for multiple field operations. The machine aims to minimize manual labor, save time, and increase operational efficiency, making it an affordable and practical solution for small-scale farmers and gardeners. The design calculations for engine power, soil draft force, seed rate, fertilizer flow, and structural safety have been carried out to ensure reliable and efficient performance under typical working conditions.
