The 3WPZ-1000G is a specialized self-propelled sprayer designed for tall crops and large-scale agricultural operations. Featuring an air-conditioned cab sprayer design, it prioritizes operator comfort while delivering exceptional crop protection performance. As a versatile agricultural sprayer, it combines mechanical drive reliability with multi-functional capabilities, including pesticide spraying, fertilizer spreading, and sanitary epidemic prevention sprayer functions. This tall crop sprayer is engineered to handle high-growing crops and uneven terrain, making it a top choice for farmers caring for corn, sorghum, and other tall plants. With its durable construction and user-centric design, the 3WPZ-1000G stands out as a premium solution for professional crop care and public health applications.
The adjustable air-conditioned cab is a standout feature, providing heating and cooling to keep operators comfortable in extreme temperatures. This design not only reduces fatigue during long workdays but also protects against pesticide drift, safeguarding operator health. The cab’s ergonomic layout places controls within easy reach, enhancing usability and reducing stress.
Engineered as a tall crop sprayer, the 3WPZ-1000G offers ample ground clearance to navigate over high-growing plants without damage. The spray boom’s flexible lifting range allows it to adjust to different crop heights, ensuring thorough coverage from the base to the upper foliage. This adaptability makes it ideal for corn, sorghum, and other tall crops requiring mid-stage pesticide application.
The mechanical drive sprayer configuration delivers consistent performance and easy maintenance. The uniquely designed 8-speed gearbox ensures smooth shifting, allowing operators to adjust speed to match field conditions. Four-wheel drive provides superior traction on uneven terrain, while the four-wheel steering enhances maneuverability in tight spaces. This robust drive system ensures the machine handles demanding tasks with ease.
This multi-functional agricultural equipment supports a range of attachments, including rear-suspended centrifugal fertilizer spreaders and intertillage fertilizer applicators. These additions extend its capabilities beyond crop protection to include nutrient application and soil cultivation. The machine’s versatile design eliminates the need for separate equipment, saving farmers time and investment.
The spray boom, crafted from aluminum, features hydraulic lifting and folding functions for easy storage and transportation. The 3-cylinder plunger pump delivers consistent pressure, ensuring uniform atomization and effective pesticide application. Safety features include guardrails on the medicine tank side and foot pedals for easy access, enhancing operator safety during maintenance and refueling.

Specialized for corn, sorghum, and other tall crops, the 3WPZ-1000G provides early and mid-stage pesticide application without damaging plants. Its high ground clearance and adjustable spray boom ensure thorough coverage of upper foliage, targeting pests and diseases that threaten tall crop health. The gentle atomization prevents leaf damage, preserving crop quality and yield.
This cash crop sprayer excels in protecting vegetables, fruits, Chinese herbal medicines, and forage grasses. It handles seedling-stage weed control and pest management with precision, supporting healthy growth of high-value crops. The machine’s versatile spray settings allow it to adapt to different crop types and application needs.
Beyond agricultural use, the 3WPZ-1000G serves as a reliable sanitary epidemic prevention sprayer for large-scale public health applications. It can be used to disinfect public spaces, farms, and industrial areas, helping control the spread of pathogens. The machine’s large coverage area and efficient spraying make it ideal for epidemic prevention efforts.
With optional attachments, the machine functions as a fertilizer spreader and intertillage tool. It distributes granular fertilizers evenly across fields and supports intertillage topdressing for crops like corn, enhancing nutrient absorption and soil health. This multi-functional use makes it a valuable asset for comprehensive farm management.

Poor cooling often results from low pressure in the air conditioning pipeline. Check the pipeline pressure and recharge with Freon to restore optimal cooling performance. Regular maintenance of the air conditioning system ensures the air-conditioned cab sprayer remains comfortable in hot weather.
Slow boom operation is typically due to low hydraulic oil levels. Check the hydraulic oil tank’s oil window; if the level is below two-thirds, add the recommended hydraulic oil. Ensuring proper oil levels keeps the hydraulic system functioning smoothly, allowing the boom to lift and open efficiently.
Inconsistent atomization can be fixed by adjusting water pressure and valve settings. Open the cab’s right window, adjust the water pressure regulating switch to the optimal level, and fully open all branch valves. This ensures uniform pressure across all nozzles, resulting in consistent spray coverage and effective crop protection equipment performance.
