The 3WPZ-1000 self-propelled sprayer is a high-power, large-capacity agricultural sprayer designed for wide-area crop protection and multi-functional farming. As a leading large-capacity sprayer, it features a spacious medicine tank and extended spray boom, making it perfect for large-scale farms growing grains, vegetables, and economic crops like shrubs. What sets this self-propelled boom sprayer apart is its compatibility with optional fertilizer spreaders, turning it into a dual-purpose tool for both pesticide application and granular fertilizer dissemination. With four-wheel drive and four-wheel steering, it delivers stability and maneuverability, while advanced filtration and mixing systems ensure consistent, reliable results every time.
The 1000L medicine tank provides ample capacity for extended work sessions, reducing the need for frequent refills and boosting efficiency. Its unique design lowers the machine’s center of gravity, enhancing stability during operation—even on uneven terrain. Equipped with an enlarged high-efficiency filter, the tank prevents nozzle clogs by trapping debris and impurities, ensuring uninterrupted spray flow and uniform application.
The spray boom offers an extended reach, covering a broader area per pass to minimize work time on large fields. Available in multiple lengths, the boom features hydraulic lifting and folding mechanisms for easy adjustment and storage. An angle adjustment cylinder allows precise control over the boom’s height and position, adapting to different crop heights and row spacings. Crafted from durable aluminum, the boom resists corrosion and damage from agricultural chemicals.
This fertilizer spreader compatible sprayer can be optionally fitted with a rear-suspended centrifugal double-disc fertilizer spreader or intertillage fertilizer applicator. This dual-purpose design lets you switch seamlessly between spraying pesticides and sowing granular fertilizers, reducing the need for multiple farming tools. The fertilizer spreading width matches the spray width, ensuring even coverage and minimizing crop disturbance.
Powered by a four-cylinder water-cooled inline diesel engine, the sprayer delivers consistent power for demanding wide-area tasks. The eight-speed gearbox ensures smooth shifting, allowing you to adjust speed based on crop density and application needs. Four-wheel drive and four-wheel steering provide excellent traction and maneuverability, even on large, open fields or slightly sloped terrain. Low fuel consumption and durable components make it a cost-effective choice for large-scale farming operations.

Ideal for large-scale farms, this wide-area agricultural sprayer excels in pest, disease, and weed control for rice, wheat, corn, and vegetables. Its wide spray coverage and large medicine tank make it efficient for covering extensive plots in minimal time.
Perfect for economic crops like shrubs, fruits, and Chinese herbal medicines, the sprayer delivers targeted application to protect valuable crops. The adjustable spray boom and precise pressure control ensure gentle, effective coverage without damaging delicate plants.
Before planting, the sprayer is effective for large-scale soil treatment, including weed prevention and soil disinfection. Its wide reach and uniform application ensure every part of the planting area is prepared for optimal seed germination.
With the optional centrifugal double-disc fertilizer spreader, the sprayer becomes a versatile tool for sowing granular fertilizers and intertillage topdressing for crops like corn. This dual functionality reduces equipment costs and streamlines farming operations.
Check the waterway distributor and ensure the stop valve handle associated with the jet agitator is fully open. If the valve is partially closed, it restricts water flow to the agitator. Also, inspect the agitator nozzles for clogs—clean them with water if debris is present.
Unscrew the liquid medicine filter cover and remove the filter element. Rinse the filter screen thoroughly with clean water to remove accumulated debris or chemical residues. Reinstall the filter element and cover in sequence to restore consistent pressure.
Adjust the angle of the cable to ensure it’s as straight as possible, minimizing friction. Check for any kinks or tangles in the cable that might hinder movement. If the cable is worn or stretched, replace it with a new one to ensure reliable operation of the discharge plate.
