3. Working Principle, Materials & Application Scenarios

3.1 Advanced Roller Compression Technology

The core operational advantage of the 9YG-1.25A lies in its 18-roller fixed chamber design, which offers superior reliability over belt-type balers in abrasive or wet conditions.
The working principle begins with the 2150mm wide spring-tooth pickup mechanism, which lifts the crop (straw, hay, or silage) from the windrow. The crop is then actively fed into the chamber via a dynamic "Auger + Dial Tooth Roller" system. This semi-forced feeding mechanism is critical for preventing blockages, a common issue when harvesting damp rice straw in the Korean climate. Once inside the chamber, the 18 steel rollers, driven by heavy-duty chains, rotate to tumble the crop into a tight cylindrical shape. As more material enters, the density increases from the core outwards. Unlike belt balers that rely on tension arms, the steel rollers provide mechanical compression that does not falter under the high pressure required for silage (up to 200 kg/m³). When the pre-set density is reached, the sensor triggers the automatic net binding system, wrapping the bale securely in seconds before ejection.

3.2 Material Metallurgy & Durability

Durability is non-negotiable for agricultural machinery operating in the demanding terrains of East Asia and North America; therefore, EVER-POWER utilizes premium-grade metallurgy.
The 18 compression rollers are fabricated from high-strength alloy steel, treated to resist the abrasive nature of silica-rich crops like rice straw. The chassis is constructed from reinforced structural steel to withstand the torsional stresses of traversing uneven paddy fields or hilly pastures. Crucially, the drive system features upgraded heavy-duty chains (comparable to 20A industrial standards), which are essential for transferring the high torque required to compress dense bales without stretching or snapping. The gears and sprockets undergo advanced heat treatment (carburizing and quenching) to achieve a surface hardness of HRC 58-62, ensuring longevity even under continuous maximum-load operation. The surface finish involves electrostatic powder coating, providing superior corrosion resistance against humid environments and fertilizers.

3.3 Global & Local Application Scenarios

The 9YG-1.25A is engineered to be a versatile workhorse, adaptable to specific regional agricultural practices and crop types.
In South Korea, the primary application is the collection of rice straw immediately following the harvest. Korean farmers face a narrow window between harvest and winter; this baler's high speed and ability to handle slightly damp straw make it indispensable for producing "Whole Crop Rice Silage" (WCS) for the beef industry. In North America and Europe, the machine excels in haylage production and corn stalk baling for biomass energy or animal bedding. Its high density is particularly valued here for reducing transport logistics costs. Furthermore, in nations like Russia and Mongolia, where vast pasturelands require equipment that can endure rough terrain, the trailed design with a wide wheel track (2450mm) offers exceptional stability. The machine is also fully capable of handling alfalfa, wheat straw, and soybean residue, making it a comprehensive solution for mixed-farming operations.

4. Global Regulatory Compliance & Land Management

Compliance with environmental regulations regarding crop residue management is a critical driver for the adoption of high-performance balers like the 9YG-1.25A.

• South Korea (Fine Dust Management): The Korean government actively enforces strict bans on open field burning of agricultural residues to combat severe air pollution and fine dust issues. The Wastes Control Act and local ordinances mandate proper disposal or utilization of rice straw. The 9YG-1.25A enables farmers to comply by efficiently converting what was once waste into valuable livestock feed or biomass fuel, often qualifying for government subsidies for eco-friendly farming equipment.
• European Union (CAP): Under the Common Agricultural Policy (CAP), farmers are incentivized to maintain soil organic matter and reduce carbon emissions. Baling straw for renewable energy or bedding, rather than burning, aligns with cross-compliance standards required for EU subsidies.
• China (Blue Sky Defense War): Similar to Korea, China imposes rigorous penalties for straw burning. The Ministry of Agriculture promotes the comprehensive utilization of straw (fertilizer, feed, fuel), creating a massive demand for reliable balers that can clear fields quickly to facilitate crop rotation.

5. Market Trend Analysis: The Shift to High-Density Baling

Firstly, the "Silage Revolution" in Asia continues to grow. Traditional dry hay baling is being supplemented by high-moisture silage baling (WCS), which requires balers that can handle heavy, wet crops without jamming. The roller-type compression of the 9YG-1.25A is technically superior for this application compared to belt balers, which often struggle with wet adhesion.

Secondly, Speed and Automation are non-negotiable. The transition from twine to net binding, featured in this model, is a dominant trend. Net binding reduces the wrapping cycle from minutes to seconds, protects the bale shape better against the weather, and is easier to remove for feeding. EVER-POWER aligns with these trends by offering a machine that balances high-tech performance with the durability required for intensive seasonal work.

11. FAQ

Q1. How does the price of the 9YG-1.25A baler compare to European brands like Claas or Kuhn delivered to South Korea?

A1. The EVER-POWER 9YG-1.25A is engineered to offer a competitive edge, typically priced at approximately 35-40% of the cost of comparable European models like Claas or Kuhn. Despite the lower cost, we utilize high-grade alloy steel rollers and heavy-duty 20A chains that match western performance standards. For delivery to South Korean ports like Busan or Incheon, our proximity allows for significantly lower shipping costs and faster lead times compared to European suppliers.

Q2. What is the minimum tractor horsepower required to operate this round baler efficiently in hilly terrains?

A2. While the technical specification lists a minimum requirement of 75 kW (approx. 100 HP), for hilly terrains often found in Jeolla or Gangwon provinces, we recommend a tractor with at least 110-120 HP. This ensures sufficient power reserve for both the PTO drive to compress high-density bales and the traction required to tow the 4472 kg unit up inclines without straining the engine.

Q3. Can this baler handle wet rice straw for silage production without clogging the feeding mechanism?

A3. Absolutely. This is a key feature of the 9YG-1.25A. It utilizes a specialized "Auger + Dial Tooth Roller + Roller" feeding system specifically designed for "semi-forced" feeding. This active feeding mechanism aggressively grabs wet, slippery rice straw and forces it into the chamber, virtually eliminating the blockage issues common with passive pickup systems found on older models.

Q4. Where can I purchase spare parts like pickup tines or roller bearings if I am located in Gyeonggi-do?

A4. We have established a robust logistics network. For common consumables like pickup tines (spring teeth) and bearings, we can ship directly via international courier to Gyeonggi-do within 3-5 days. Furthermore, we provide a "Critical Spare Parts Kit" with every machine purchase, and many components (like bearings and chains) utilize standard ISO specifications, meaning compatible replacements can often be sourced locally in Korea.

Q5. Which binding material does the 9YG-1.25A use, and is it compatible with standard Korean agricultural nets?

A5. The 9YG-1.25A uses an automatic Net Binding system. It is fully compatible with standard agricultural net rolls sized at 1.25m width (2000m length per roll), which are widely available in the Korean market. The net binding system is generally preferred over twine for silage as it provides better coverage, maintains bale shape better during wrapping, and is faster to apply.

Q6. How do I maintain the 18-roller compression chamber to ensure long-term durability?

A6. Maintenance is straightforward. The most critical step is regular lubrication of the chain drive system and roller bearings using high-quality grease, especially after washing the machine. Since the rollers are steel (not rubber belts), they do not require tension adjustment, but you should visually inspect the scraper gaps to prevent material buildup. We provide a detailed English/Korean maintenance manual with every unit.

Q7. Does EVER-POWER offer customization for the hitch system to fit my specific tractor model?

A7. Yes, as an OEM manufacturer, we offer customization services. If your tractor utilizes a specific drawbar height or hydraulic coupling standard different from our default configuration, please specify this during the inquiry process. We can modify the traction head and hydraulic interfaces to ensure a "plug-and-play" experience upon delivery to your farm.

Q8. What is the typical lead time for a container order of these balers to the USA or Australia?

A8. For standard orders, our production lead time is typically 15-20 days. Shipping times vary by destination; for the West Coast of the USA or major Australian ports, ocean freight usually takes an additional 20-30 days. We recommend placing orders 2 months prior to the harvest season to ensure timely arrival and setup.

Q9. How does the "floating" pickup protection feature work when encountering rocks or obstacles?

A9. The 9YG-1.25A features a specialized hydraulic suspension for the pickup reel. When the pickup tines encounter a rigid obstacle like a rock or tree root, the mechanism allows the pickup unit to "float" or lift automatically to clear the obstacle, then immediately return to the working height. This prevents damage to the tines and the main rotor, significantly reducing downtime and repair costs.
