China, one of the world’s three major industrial tomato-producing regions, has taken a significant step toward agricultural mechanization with the development of the 4FZ-80 self-propelled tomato harvester, launched in 2024.
Previously, industrial tomato harvesting relied heavily on imported machinery, which often came with high purchase costs and challenges in after-sales service. The domestically developed machine addresses these issues through several innovative technologies.
Its harvesting header features crop-row separation, lifting, gathering, and reciprocating cutting mechanisms to handle tangled and fallen tomato vines. An inertia-based vibration system then separates tomatoes from vines, while a flexible conveying system equipped with film-removal devices and air blowers helps eliminate plastic film, soil, and leaf debris.
For improved tomato quality, a spectral-reflection-based color sorter identifies and removes unripe green tomatoes within a detection window of just 0.15 seconds.
Working alongside transport vehicles, the 4FZ-80 achieves a harvesting capacity of up to 80 tons per hour, equivalent to the output of approximately 400–800 manual harvesters. Its total harvesting loss rate is no more than 4.5%, mechanical damage rate no more than 5%, and foreign material content no more than 3%.
To date, the machine has covered more than 50,000 mu (approximately 3,333 hectares) in harvesting operations, demonstrating the growing capabilities of China's domestically developed agricultural machinery.
