The 3WPZ-800C self-propelled sprayer is a high-performance agricultural sprayer designed to meet the diverse needs of modern farming. As a versatile self-propelled boom sprayer, it combines flexibility, power, and efficiency, making it stand out among crop sprayers and traditional tractor sprayers. Engineered with four-wheel drive and multiple steering modes, it navigates easily through muddy fields and confined spaces, adapting to various working environments. Whether you’re protecting food crops, vegetables, or economic crops, this high-efficiency agricultural sprayer delivers consistent results, ensuring effective disease, pest, and weed control while enhancing operational convenience.
The 3WPZ-800C features four-wheel drive and four-wheel steering, providing exceptional maneuverability in tight spaces and uneven terrain. Unlike suspended sprayers, this self-propelled model moves freely in muddy fields, reducing the risk of getting stuck and improving overall efficiency. The drive system is engineered for reliability, ensuring consistent performance across long working hours.
Powered by a four-cylinder in-line water-cooled diesel engine, this agricultural sprayer delivers ample power while maintaining fuel efficiency. The engine’s design ensures durability and adaptability, performing well in various weather conditions and workloads. It outperforms smaller sprayers in terms of power, making it suitable for large-scale operations and challenging environments.
The spray system includes a front-mounted aluminum spray rod with hydraulic lifting and folding capabilities, allowing for easy adjustment of height and coverage. The three-cylinder plunger pump ensures consistent liquid flow and pressure, while the jet and reflux stirring system keeps the medicated liquid well-mixed for uniform application. The spray rod’s design enables multi-angle spraying, making it ideal for small plots and confined areas where remote-controlled drones may struggle.
The engine and medicine tank feature a sunken design that lowers the machine’s center of gravity, enhancing stability and safety during operation. The adjustable cab provides a comfortable working environment, reducing operator fatigue during long sessions. The uniquely designed 8-speed gearbox ensures smooth shifting, while the drum brake system offers reliable stopping power, making this boom sprayer both safe and easy to operate.

This self-propelled sprayer excels in full-process pesticide application for medium and short crops, providing effective disease, pest, and weed control. It is also suitable for early and mid-stage pesticide application for taller crops, adapting to different growth stages with ease. From rice and wheat to corn and sorghum, as well as vegetables and shrubs, the 3WPZ-800C delivers consistent results across a wide range of crops.
Beyond crop protection, this agricultural sprayer is ideal for large-scale soil treatment before sowing, weed control during seedling stages, and pest prevention for fruits, Chinese herbal medicines, forage grasses, and garden flowers. Its dual-purpose design allows for front spraying and rear fertilizer spreading, with matching widths to minimize seedling burden, making it more convenient than traditional tractor sprayers.
The 3WPZ-800C is also suitable for large-scale health and epidemic prevention spraying, offering a versatile solution for sanitization needs. Its high efficiency and wide coverage make it a valuable tool for both agricultural and non-agricultural applications.

Check the air intake nozzle by applying soap solution. If bubbles appear, tighten the air needle inside the nozzle to seal any leaks. Proper tire pressure is essential for the self-propelled boom sprayer’s performance, so regular checks are recommended.
Inspect the hydraulic oil level in the tank. If the level is below two-thirds of the oil window, add the recommended hydraulic oil to restore proper functionality. The hydraulic system is critical for the spray rod’s operation, so maintaining the correct oil level is key.
Adjust the angle of the guy wire to ensure it remains straight. Misalignment can prevent the wire from pulling the material leakage plate apart, so proper adjustment will ensure smooth fertilizer spreading during operation.
