Powered by a reliable four-cylinder water-cooled inline diesel engine, the 3WPZ-800S delivers consistent power for demanding tasks. Its mechanical drive system works seamlessly with the four-wheel drive setup to ensure reliable performance in all conditions. The steering system supports four modes—four-wheel, two-wheel, diagonal, and four-wheel drive—adapting to diverse terrain needs. The spray boom is crafted from lightweight yet durable aluminum, with a hydraulic lift mechanism for easy height adjustment. The medicine tank is constructed from high-density materials that resist chemical corrosion, while the three-cylinder plunger pump ensures steady pressure for optimal atomization. Drum brakes provide reliable stopping power, and the pneumatic rubber tires offer durability and traction on wet or soft soils.

The 3WPZ-800S self-propelled sprayer is a high-performance agricultural sprayer engineered specifically for challenging farming environments like paddy fields, muddy lands, and waterlogged areas. Designed to meet the full-cycle pest and weed control needs of rice and other crops, this four-wheel drive sprayer combines power, versatility, and durability to elevate your farming efficiency. Its unique steering system and adaptive design make it a top choice for multi-season rice cultivation areas, where stability and maneuverability are non-negotiable. Whether you’re tackling large-scale crop protection or sanitary epidemic prevention, this farm sprayer delivers consistent results you can rely on.
Equipped with a four-wheel drive and four distinct steering modes, the 3WPZ-800S offers unmatched flexibility in tight or uneven terrains. The four-wheel steering sprayer minimizes turning radius, allowing easy navigation between crop rows without damaging seedlings. This system ensures superior traction on muddy or waterlogged fields, where standard sprayers often struggle. The smooth-shifting 8-speed gearbox enhances control, letting you adjust speed based on crop density and terrain conditions.
With a thoughtfully designed ground clearance, this mud field sprayer glides over crops throughout their growth cycle without causing compression or damage. The solid, durable tires are optimized for wet conditions, providing excellent flotation to prevent sinking in muddy soils. The machine’s balanced weight distribution further enhances stability, even when navigating sloped or uneven paddy field surfaces.
The hydraulic sprayer features a front-mounted, hydraulically lifted aluminum spray boom that adjusts easily to match crop height. The spray boom’s robust construction ensures longevity, while its flexible adjustment range allows targeted application for different crop stages. The integrated medicine tank boasts dual mixing functions—jet stirring and reflux stirring—that ensure pesticides or fertilizers are blended uniformly, delivering consistent coverage across every inch of your fields. This eliminates uneven application issues common with less advanced sprayers.
The adjustable cab prioritizes operator comfort during long work hours, with intuitive controls that simplify sprayer operation. All critical functions, from spray boom adjustment to pressure control, are within easy reach. The crop sprayer uses high-quality, corrosion-resistant components, including stainless steel nozzles and a rugged frame, to withstand the harsh conditions of agricultural work. Low vibration and fast acceleration from the diesel engine reduce operator fatigue and boost productivity.

Ideal for paddy field sprayer applications, the 3WPZ-800S excels in full-cycle pest, disease, and weed control for rice, wheat, soybeans, and peanuts. Its ability to navigate muddy conditions makes it perfect for rice cultivation, where waterlogged soils are common.
Specifically engineered for muddy fields and waterlogged areas, this sprayer avoids sinking or getting stuck, ensuring uninterrupted work even in challenging moisture conditions. It’s a must-have for farms in regions with heavy rainfall or poor drainage.
Beyond crop protection, the 3WPZ-800S is suitable for large-scale sanitary and epidemic prevention spraying. Its wide coverage and efficient liquid distribution make it effective for disinfecting farmyards, storage facilities, and large agricultural plots.
In multi-season rice planting regions, where quick turnaround between crops is essential, this self-propelled boom sprayer offers fast, efficient application that gets fields ready for the next planting cycle without delays.
Inspect the tire treads regularly for damage or wear. If you notice cracks, bulges, or excessive wear, replace the tires promptly to maintain traction and stability. Ensuring proper tire pressure (as recommended in the manual) also helps absorb shocks on rough terrain.
Check the hydraulic oil level in the reservoir—ensure it meets the minimum requirement (not lower than two-thirds of the oil window). If the level is low, add the recommended hydraulic oil. Also, inspect for any clogs or leaks in the hydraulic lines that might restrict flow.
The sprayer’s jet and reflux stirring functions work best when the medicine tank is filled to the recommended level. Avoid overfilling or underfilling, as this can disrupt mixing. Additionally, run the stirring system for a few minutes before starting application to ensure thorough blending of chemicals.
