　　Details of the 4QZ-20 Green Forage Harvester

　　1. Grain crushing: a roller-type grain crusher employing imported technology.

　　1) High grain breakage rate: no more than one whole corn kernel per liter of forage.

　　2) Working principle of the double-roller crusher: The two rollers are floating and highly flexible, allowing foreign objects to be smoothly discharged upon entry, thereby reducing the failure rate.

　　2. Ultra-High-Power China IV Engine

　　Equipped with a renowned 380-horsepower super-high-power engine, delivering robust performance, excellent fuel efficiency, and easy maintenance.

　　3. Dual-disc cutterbar with an increased cutting width of 3,240 mm for high operational efficiency and excellent feed performance.

　　A metal-foreign-object-infeed prevention device has been installed on the cutting platform, reducing the likelihood of metal foreign objects being fed into the system.

　　4. Fast efficiency:

　　The feed inlet width reaches 750 mm, and the harvesting width is 3,240 mm, ensuring ultra-high material throughput and effective flattening of the material, while maintaining a stable material flow throughout operation.

　　5. Hobbing-type chopping:

　　The cutter roller is designed using advanced foreign technology, with blades arranged in a four-row herringbone pattern. The chopping length is continuously adjustable in two settings—9 to 22 mm—ensuring precise and optimal feed length.

　　6. Automatic Knife Sharpening

　　Equipping the machine with an automatic knife-sharpening system ensures consistent chopping quality.

　　7. Automatic Lubrication

　　An imported, well-known brand automatic lubrication system has been installed to ensure bearing life and enhance machine stability.

　　8. Retrofit with dual hydrostatic drive

　　Both the travel system and the feed system are fully equipped with imported dual-hydrostatic drives, which are flexibly integrated to significantly reduce the failure rate.

　　9. Installation of a thin-oil lubrication system:

　　An automatic thin-oil lubrication system has been installed, ensuring continuous lubrication of all the vehicle’s chains, thereby extending their service life and enhancing operational reliability.

　　10. Good stability:

　　Equipped with 500-series radial vacuum wide tires to reduce compaction on the working surface and ensure no trenching occurs.

　　11: High configuration

　　Ultra-high specifications ensure more convenient operation and greater comfort during summer work.

Technical Specifications

　　In 2025, Muzhe Company will continue to reward its broad user base with more powerful new products, more comprehensive technological upgrades, and more favorable purchase policies, thereby committing itself to making an even greater contribution to China’s agricultural modernization.
