Agricultual 9YG-2.2 Round Hay Baler 2200mm Pickup Smart Net Wrapping Baler

High-Density 18-Roller Compression, 2200mm Pickup, Automatic Net Wrapping, and Intelligent Touch Screen Monitoring

Equipment Overview: The Forage Harvesting Expert

For modern large-scale ranches and professional straw recycling operations, achieving maximum bale density and feed preservation is critical. The 9YG-2.2 is an advanced trailed round baler net wrapping system engineered to transform tough agricultural residues into perfectly cylindrical, weather-resistant bales.

Unlike standard balers, this model features a robust 18-roller compression chamber and a continuous screw feeding mechanism. This guarantees uninterrupted material flow even when processing high-moisture alfalfa, dense corn stalks, or slippery wheat straw. The resulting high-density round bales drastically reduce transport logistics costs and protect the inner forage from spoilage, making it the premier choice for commercial silage preparation.

Technical Parameters (Model 9YG-2.2)

Intelligent Monitoring: Total Precision Control

What elevates the 9YG-2.2 above a standard forage harvester supplier asset is its state-of-the-art brain. It is equipped with a handheld color touch screen that operates stably and reliably in harsh field conditions. Combined with a high-precision displacement sensor, the bale weight and chamber pressure can be precisely controlled from the tractor cab.

• Dual-Mode OS: The operating system is highly intuitive, offering both automatic and manual modes for seamless harvesting regardless of operator experience.
• Cost-Control Netting: The high-precision sensor accurately positions and monitors the exact number of net-wrapping loops. This prevents excessive net usage, significantly reducing consumable costs over a harvesting season.
• Real-Time Diagnostics: The entire baling process is fully monitored, making the equipment's operating status, from hydraulic pressure to gate locking, clear at a single glance.

Global Sourcing & Advanced Lubrication

Field breakdowns are unacceptable. To guarantee continuous operation, the key components of the whole machine—such as the drive shaft, heavy-duty bearings, clutch mechanisms, heavy-pitch chains, and the electronic control system—are globally sourced from world-renowned brands. This ensures unparalleled power transmission from your 110-150kW tractor directly to the 18 compression rollers.

Furthermore, maintenance is virtually autonomous. The fully automatic thin oil lubrication system ensures the smooth operation of the entire machine's complex chain drive network, vastly extending service life. Simultaneously, the heavy-load grease lubrication points adopt a centralized oil supply method, reducing daily maintenance time from hours to minutes.

Operational Flow & Reliability Maintenance

Understanding the mechanical synergy of a corn stalk baling machine is key to zero-downtime harvesting:

• Gathering & Feeding: The spring-tooth pickup lifts the swath while the continuous screw forcibly channels it to the rotor. Prevention: Monitor hydraulic float settings to prevent the pickup tines from striking rocks, which can shatter teeth and jam the auger.
• Chamber Rolling: The 18 steel rollers grip the forage, spinning it under increasing hydraulic pressure until the 1220mm diameter is reached. Prevention: Adhere strictly to the automatic lubrication alerts on the touch screen to prevent roller bearing seizure.
• Net Wrapping: The smart sensor triggers the net actuator, applying perfect tension. Prevention: Regularly clean the displacement sensors and optical eyes of dust and chaff to prevent endless wrapping cycles or failed net cuts.

Application Scenarios & Moisture Compatibility

The 9YG-2.2 excels in heavy, demanding crops, producing perfectly round 1400x1220mm bales. For peak fermentation and storage, observe the following moisture parameters:

• Tractor Requirement: Heavy-duty trailed design necessitates a tractor outputting 110 to 150 kW via the PTO to drive the 18 rollers under maximum hydraulic load.
• Alfalfa & Legumes: Baler performs optimally at 17%-23% moisture. The roller chamber is gentler on delicate leaves than belts, preserving high-protein forage.
• Corn Stalks & Grain Straw: Target 10%-23% moisture. The aggressive screw feed prevents bridging of thick, unyielding stalks.
• Topography: Ideal for expansive ranches and commercial fields. Maximum safe operating slope is ≤8°.
