Fertilizer spreaders are the core equipment for precision fertilization. Traditional spreaders typically rely on mechanical dampers or manual valves to adjust fertilizer output, with operators relying on experience to operate them. This makes it difficult to achieve variable-rate fertilization based on soil nutrient distribution and crop growth needs—over-fertilization leads to waste and environmental pollution, while under-fertilization reduces crop yields. Modern precision agriculture requires spreaders to integrate with GPS positioning and soil quality data to achieve "fertilization on demand."
Our linear actuators are precision drive components specifically designed for fertilizer discharge control in fertilizer spreaders. By receiving commands from the spreader's control system, the actuators precisely control the opening and closing of the fertilizer discharge port and the tilt angle of the spreading disc, enabling accurate fertilizer metering and variable-rate application.

Key features and benefits
Precise flow control for variable-rate fertilization
The key to fertilizer application lies in "precision"—insufficient fertilization leads to reduced crop yields, while over-fertilization results in fertilizer waste and environmental pollution. Our linear actuators provide precise stroke control and extremely high repeatability, ensuring uniform fertilizer coverage of the target area by precisely controlling the opening and closing of the fertilizer discharge port and the tilt angle of the spreader disc. Combined with GPS positioning and soil quality data, the system can precisely distribute fertilizer to specific areas.
Rapid response for improved fertilization efficiency
Chemical fertilizer application typically must be completed within critical windows of crop growth, making time extremely tight. Our linear actuators feature extremely high response speeds—instantaneous opening and closing of the discharge port, rapid adjustment of the spreader disc angle, and swift response of the flow control valves—ensuring the fertilizer spreader reaches optimal operating condition in the shortest possible time.
Corrosion-resistant design to withstand chemical fertilizer corrosion
The actuators in fertilizer spreaders are in constant contact with various chemical fertilizers (such as urea, compound fertilizers, and potash fertilizers), placing extremely high demands on material corrosion resistance. Our linear actuators have undergone 500 hours of testing in a salt spray chamber at 40°C and 93% relative humidity, and have been subjected to chemical resistance testing by applying various chemicals directly to the actuators. The use of corrosion-resistant materials and special surface treatment processes ensures stable and reliable performance even in environments with prolonged exposure to chemical fertilizers.
Leak-free design eliminates the risk of hydraulic fluid contamination in farmland
The greatest risk facing hydraulically driven fertilizer spreaders is hydraulic fluid leakage—if a hydraulic line ruptures, the fluid will directly contaminate farmland, affecting crop growth and soil quality. Our linear actuators utilize a fully electric design with no hoses, pumps, or compressors. This zero-leakage design fundamentally eliminates the risk of hydraulic fluid contaminating farmland.
High protection rating to withstand field dust and mud
Fertilizer application typically takes place in dry, dusty fields or muddy fields after rain, placing high demands on the equipment's protection rating. Our electric linear actuators feature a high protection rating, providing full resistance against the intrusion of dust, mud, and moisture. All actuators undergo a comprehensive series of endurance tests to ensure they can handle various loads and function reliably throughout their entire service life.
Maintenance-free design to reduce operating costs
The operating season for fertilizer spreaders is concentrated and demanding; frequent maintenance directly impacts equipment availability and operational efficiency. Our linear actuators feature a maintenance-free design, eliminating the need for regular lubrication or replacement of wear parts. Our all-electric solution has been validated through tens of thousands of endurance tests, ensuring stable operation throughout the fertilizer spreader's entire lifecycle.
Smart integration for precision farming
The electric actuators provide precise position feedback, and their smart interfaces can integrate with virtually any type of control system. By combining position data with GPS tracking systems and soil quality indicators, the system can precisely distribute fertilizer to specific areas.
