The 3WPZ-800E self-propelled sprayer is a flagship product in the agricultural sprayer series, designed to deliver exceptional performance for modern farming needs. As a versatile boom sprayer and agricultural sprayer, it combines power, flexibility, and reliability to tackle disease, pest, and weed control across a wide range of crops. Unlike traditional tractor sprayers, this self-propelled model offers superior maneuverability, making it ideal for both large-scale farms and confined plots. Whether you’re managing food crops, vegetables, or economic crops, the 3WPZ-800E stands out as a high-efficiency crop sprayer that streamlines field operations and enhances productivity.
Equipped with four-wheel drive and multiple steering modes, the 3WPZ-800E navigates effortlessly through muddy fields and uneven terrain. This self-propelled boom sprayer outperforms conventional options by offering unmatched flexibility, allowing farmers to move freely without compromising stability. The robust drive system ensures consistent performance even in challenging working environments, making it a reliable choice for diverse agricultural settings.
At the heart of this agricultural sprayer is a high-performance diesel engine that balances power and fuel efficiency. The four-cylinder water-cooled design ensures durability and adaptability, operating smoothly across different workloads. Compared to suspended sprayers, the 3WPZ-800E delivers more power while consuming less fuel, reducing operational costs and environmental impact.
The hydraulic sprayer configuration includes a durable aluminum spray rod with hydraulic lifting and folding capabilities. This design allows for easy adjustment of spray height and coverage, enabling multi-angle spraying in small plots or confined spaces. The three-cylinder plunger pump ensures consistent liquid distribution, while the jet and reflux stirring system keeps the medicated liquid well-mixed for uniform application.
The engine and medicine tank feature a sunken design that lowers the machine’s center of gravity, enhancing safety and stability during operation. The adjustable cab provides comfort for long working hours, while the reliable drum brake system ensures secure stopping power. As a china sprayer engineered for durability, the 3WPZ-800E withstands the rigors of daily agricultural use.

This self-propelled sprayer is ideal for the full-process pesticide application on medium and short crops, providing effective disease, pest, and weed control. It also excels in early and mid-stage pesticide application for taller crops, adapting to different growth stages with ease. The versatile design makes it suitable for rice, wheat, soybeans, peanuts, corn, and sorghum, as well as shrubs and other economic crops.
Beyond crop protection, the 3WPZ-800E is suitable for large-scale soil treatment before sowing, weed control during seedling stages, and pest prevention for vegetables, fruits, Chinese herbal medicines, forage grasses, and garden flowers. Its dual-purpose functionality allows for front spraying and rear fertilizer spreading, with matching widths to minimize seedling burden, making it more convenient than traditional tractor sprayers.

Inspect the tire treads regularly for damage. If any wear or tears are found, replace the tires promptly to ensure smooth and safe operation. Proper tire maintenance is key to maximizing the performance of this self-propelled sprayer.
Check the hydraulic oil level in the oil 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 performance, so regular checks are essential.
Adjust the angle of the guy wire to ensure it remains as straight as possible. Misalignment can hinder the wire’s performance, so proper adjustment will ensure smooth fertilizer spreading during operation.
