Product Uses
Ideal for rice harvesting in concentrated, high-yield paddy fields, this machine’s wide cutting width and efficient threshing system reduce operation time and labor costs. It handles mature rice crops with ease, minimizing grain loss and ensuring maximum harvest efficiency.
Beyond rice, this multicrop harvester excels in harvesting wheat and other small to medium-sized cereal crops. The semi-fed design ensures even threshing, preserving grain quality while handling different crop densities effectively.
With its high ground clearance and stable track system, the harvester performs reliably in muddy paddy fields or soft soil areas. It avoids getting stuck, maintaining consistent operation and reducing downtime in challenging terrains.
Agricultural machinery cooperatives and large-scale farms benefit from the machine’s large grain tank capacity, which supports continuous harvesting without frequent grain unloading. It integrates seamlessly into centralized mechanization plans, boosting overall operational efficiency.
Compatible with straw crushing and returning-to-field attachments, this harvester aligns with green agricultural practices. It can also work alongside fertilizing machines and rotary tillers, creating a comprehensive field management solution.
Product Operate Guide
Before use, check the combine harvester for sufficient fuel, oil, hydraulic oil, and coolant. Inspect the tracks or tires for wear and ensure chains and gears are properly tensioned. Verify that the cutting table, feeding drum, threshing drum, and cleaning fan are free of blockages. Check the battery level and ensure the dashboard displays function normally, and confirm the grain tank and straw handling devices are securely installed.
Start the engine following the recommended sequence and allow it to preheat to the optimal operating temperature. Adjust the gearbox settings and drive slowly into the field, keeping the cutting platform parallel to the ground. Conduct a test cut on a small area to confirm cutting height, threshing effect, and driving speed before full-scale operation.
Adjust the cutting height based on crop height, typically maintaining a low profile to minimize stubble. Keep the machine moving at a uniform speed to avoid grain damage or incomplete cutting. Choose between straw crushing and returning to the field or whole plant discharge, ensuring the straw handling system remains unobstructed. Monitor the grain tank regularly and unload grain promptly when it approaches full capacity to prevent overflow.
After harvesting, clean the cutting table, threshing drum, cleaning fan, and grain box to remove crop residues and prevent corrosion. Inspect transmission chains, gears, and hydraulic pipelines, adding lubricant or replacing parts as needed. Store the paddy rice harvester in a dry, ventilated area away from direct sunlight or moisture. Regularly replace engine oil, hydraulic oil, and filter elements to maintain consistent performance.
