Independently developed by Boshiran, the 7850 Grain Harvester redefines efficiency and versatility in large-scale agricultural operations. Combining high-capacity performance with multi-crop adaptability, it is engineered to excel in demanding environments.
Product Advantage
Single Axial Flow Threshing System:
Achieves low-impact threshing with lower grain breakage rate, preserving seed integrity and maximizing yield quality.
Multi-crop Harvesting:
Adapts to wheat, rice, soybeans, and rapeseed crops through adjustable settings. High-Efficiency Cleaning System Dual-Channel Axial Fan + two lever Sieve: Optimizes airflow and vibration patterns, grain loss keep excellent even in high-moisture conditions.
Unmatched Operational Efficiency Shared Powertrain with Boshiran 6-Row Cotton Harvester:
Utilizes a mature transmission system paired with a variable hydraulic motor (stepless drive) for smooth, fuel-efficient field navigation.
