Agriculture plays a vital role in economic development, and modern technology integration is essential for improving productivity. This paper presents the fabrication of a multipurpose agricultural machine that performs spraying, seeding, and plowing operations using solar power as the primary energy source. The system reduces manual labor, minimizes fuel consumption, and promotes eco-friendly farming. The machine consists of a solar panel, battery storage, DC motors, and mechanical assemblies for three agricultural tasks: uniform pesticide spraying, controlled seed placement at proper depth and spacing, and soil plowing for aeration. Testing on a 100 sq.m test plot demonstrates 90% spraying uniformity, 88% seed placement accuracy at 15cm spacing, plowing depth of 10cm in medium soil, and 3 hours continuous operation on solar charge, achieving 70% labor reduction and 55% cost savings compared to manual farming methods
