The 3WPZ-1000A self-propelled sprayer is a specialized agricultural sprayer engineered for challenging terrains like slopes, hills, and forest areas. As a slope field sprayer, it features a low center of gravity and stable four-wheel drive system, ensuring safe and efficient operation on uneven or inclined surfaces. This self-propelled boom sprayer offers optional semi-enclosed or fully enclosed air-conditioned cabs, prioritizing operator comfort in harsh weather conditions. Designed for pest and weed control on food crops, vegetables, and economic crops like shrubs, it also excels in large-scale sanitary epidemic prevention. Its flexible spray system and durable construction make it a reliable choice for farms in hilly or forested regions where standard sprayers struggle.
The 3WPZ-1000A’s low center of gravity design enhances stability on sloped or uneven terrain, preventing tipping and ensuring consistent performance. The low-center-of-gravity sprayer uses specially designed pneumatic rubber tires that provide excellent traction on loose or uneven soils common in hills and forests. Its balanced weight distribution and four-wheel drive system further improve mobility, allowing it to navigate narrow paths and steep slopes with ease.
Operators can choose between a semi-enclosed cab or a fully enclosed air-conditioned cab, tailored to their climate and comfort needs. The enclosed cab sprayer protects against extreme temperatures, rain, and dust, reducing operator fatigue during long work hours. The adjustable seat and intuitive control layout ensure a comfortable, user-friendly experience, even during extended operations in remote areas.
The spray boom is crafted from corrosion-resistant aluminum, with hydraulic lifting and folding mechanisms for easy adjustment. An angle adjustment cylinder allows precise control over the boom’s height and position, adapting to different crop heights and terrain contours. The hydraulic sprayer boom’s design ensures uniform coverage, even on sloped surfaces, eliminating gaps or overlaps in application. The spray bodies are strategically placed to deliver targeted coverage, protecting crops without wasting chemicals.
Compatible with optional rear-suspended centrifugal double-disc fertilizer spreaders or intertillage fertilizer applicators, this crop sprayer offers versatile functionality beyond pest control. The medicine tank features jet and reflux stirring systems, ensuring pesticides or fertilizers are mixed thoroughly for consistent application. The enlarged filter prevents nozzle clogs, even when using organic or particulate-rich formulations common in organic farming.

Designed as a slope field sprayer, the 3WPZ-1000A excels in pest, disease, and weed control for crops grown on hills or slopes, including rice, wheat, and soybeans. Its stability and traction prevent damage to crops and ensure even application on inclined surfaces.
Ideal for forest area sprayer applications, this machine navigates narrow forest paths and uneven terrain to protect trees, shrubs, and undergrowth from pests and diseases. Its adjustable spray boom reaches high and low, covering all parts of the vegetation without disturbing the surrounding ecosystem.
For medium and short-stalk crops like peanuts, vegetables, and Chinese herbal medicines, the sprayer delivers targeted, gentle application that protects delicate plants. The uniform mixing system ensures chemicals are applied evenly, avoiding burn or damage.
Beyond crop protection, the 3WPZ-1000A is effective for large-scale sanitary and epidemic prevention spraying in remote areas, farms, and rural communities. Its wide coverage and efficient liquid distribution make it a valuable tool for public health initiatives.
Inspect the air intake nozzle on the tire. Apply a soap solution to the nozzle—if bubbles form, it indicates a leak. Tighten the air needle inside the nozzle to seal the leak. If the tire continues to lose pressure, check for punctures and repair or replace the tire as needed.
Follow the steps outlined on the label attached to the seat adjustment handle. These instructions guide you through adjusting the four wheels to ensure they’re aligned straight. Proper alignment improves stability, reduces tire wear, and enhances maneuverability on slopes.
Rotate the red handle of the water distribution valve counterclockwise to adjust the water outlet pressure to the optimal level. This reduces the fineness of the mist, minimizing drift caused by wind or air movement. Additionally, avoid spraying during high-wind conditions to further prevent drift.
