Tractor-mounted sprayers are agricultural devices attached to tractors for applying pesticides, herbicides, and fertilizers to crops. They consist of a tank for holding the liquid, a pump to distribute it, and spray nozzles that ensure even coverage over the fields. This equipment helps farmers protect their crops from pests and diseases while promoting healthy growth. These sprayers can be adjusted for different field sizes and crop types, making them versatile tools in modern farming. By using tractor-mounted sprayers, farmers can efficiently manage their fields, saving time and labor while maximizing crop yields.
