The 3WPZ-600D’s parameters prioritize reliability and adaptability. Its power system relies on a compact single-cylinder diesel engine with consistent performance and low fuel consumption. The hydraulic sprayer boom, made of durable steel pipe, offers hydraulic lift and fold for convenient storage and transport. The medicine tank, with a generous capacity, uses reflux stirring to keep solutions homogeneous. The drive system employs four-wheel drive for traction on slippery or uneven terrain, while the steering system supports both two-wheel and four-wheel modes for flexibility. Reliable drum brakes ensure safe operation, and pneumatic tires are designed to handle wet and dry conditions alike. The overall structure is compact yet sturdy, with corrosion-resistant components that stand up to agricultural chemicals.

The 3WPZ-600D is a reliable, cost-effective self-propelled sprayer tailored for small to medium-sized farms and agricultural operations. Designed to balance performance and efficiency, this agricultural sprayer shines in early-stage crop care, offering seamless pest control, weed control, and fertilizer spreading capabilities. With its compact design and low fuel consumption, it’s an ideal choice for farmers focusing on rice, wheat, corn, and vegetables, adapting effortlessly to both paddy fields and dry lands while minimizing operational costs.
Equipped with a robust single-cylinder diesel engine, the 3WPZ-600D delivers sufficient power for demanding farming tasks without excessive fuel use. Its fuel-efficient design ensures long working hours on minimal fuel, making it perfect for operations covering over 20 hectares. The engine’s reliable performance shines in diverse terrains—from muddy paddy fields to hilly dry lands—providing consistent power for smooth navigation.
The boom sprayer features a hydraulic lift and fold mechanism, allowing easy adjustment of height and width to match crop rows and growth stages. Crafted from sturdy steel pipe, the spray rod resists wear and corrosion, while the 20 precision nozzles ensure uniform atomization. The waterway system maintains balanced pressure, guaranteeing that pesticides and fertilizers adhere effectively to crops, outperforming smaller sprayers in coverage and results.
With four-wheel drive and four-wheel steering, the 3WPZ-600D boasts impressive maneuverability, even in tight spaces. Its adjustable track width adapts to different crop spacings, while the pneumatic tires minimize soil compaction and crop rolling. The machine’s compact turning radius reduces overlap during spraying, saving time and resources while protecting delicate seedlings.
Designed with simplicity in mind, this crop sprayer features an adjustable cab and intuitive controls, making it easy for operators of all experience levels to use. It supports dual functions—pesticide spraying and granular fertilizer spreading—eliminating the need for multiple machines. The mechanical drive system ensures smooth operation, while easy access to components simplifies maintenance and reduces downtime.

Ideal for wheat cultivation, the 3WPZ-600D handles weeding, pest and disease control, and foliar fertilizer spraying with precision. For rice farms, it excels in applying herbicides, insecticides, and fungicides during key growth stages, as well as sowing granular fertilizers. It also supports corn seedling weeding and early-mid stage pesticide application, ensuring crops thrive without competition or damage.
For large-scale plantations of soybeans, cotton, and vegetables, this self-propelled boom sprayer provides efficient pest and disease control, covering wide areas quickly. Its adjustable spray width and pressure adapt to different crop types, from leafy greens to tall shrubs, ensuring thorough coverage without waste.
Beyond agriculture, the 3WPZ-600D is suitable for spraying hygiene and epidemic prevention disinfectants in public places. Its powerful pump and wide spray range make it effective for disinfecting parks, warehouses, and agricultural facilities, adding versatility to its utility.
First, check if the power switch is rotated to the “ON” position—this is a common oversight. If the machine has been stored for a long time, verify the battery voltage (it should be around 24V). Recharge or replace the battery if the voltage is too low, and ensure all wiring connections are secure and free of corrosion.
This problem usually involves a loose clutch wire. Inspect the clutch wire and its adjustment nut, ensuring the clutch pedal fully releases and the clutch engages properly. Tighten any loose connections or adjust the nut to restore proper clutch function.
Low water pressure is often caused by a clogged filter. Remove the filter, clean out any debris or sediment, and ensure the water flow is unobstructed. Additionally, check the pressure regulating handle to confirm it’s set to the correct position for optimal pressure.
