Review of OROS 3 HSA Header

OROS is a well-known manufacturer of agricultural machinery, particularly headers for harvesting corn and sunflower. Among the wide range of products, the OROS 3 HSA model stands out, combining innovative technologies and high reliability.

Main Characteristics of OROS 3 HSA

The OROS 3 HSA lineup includes headers with different row counts — from 6 to 8. All models are equipped with modern elements such as a cardan drive and aluminum gearboxes, which significantly lighten the construction and reduce fuel consumption.

Advantages of Using OROS 3 HSA

The OROS 3 HSA header is distinguished by its high efficiency in harvesting and chopping stalks. The integration of the chopping system allows both processes to be carried out in one pass, saving time and resources. The upgraded row units with knives reduce energy consumption and improve soil preparation.

Technological Innovations

One of the key innovations is the advanced stalk chopping system, which includes knives that chop the stalks into pieces averaging 7 cm in length. This promotes better soil treatment and reduces energy costs. Updated row units and drive systems also ensure greater reliability and durability of the equipment.

Optional Features and Additional Equipment

The OROS 3 HSA header can be supplemented with various options, such as kits for harvesting sunflower or side extensions. This allows the equipment to be customized to the specific needs of the farming enterprise.

Operation and Maintenance

Ease of use and minimal daily technical support make the OROS 3 HSA an attractive choice for farmers. The header is equipped with a system that protects it from dirt and dust, significantly reducing the need for frequent maintenance. Additionally, spare parts for the Oros header are available for purchase on our website.

Third-Generation HSA Series Header

The modernized classic model of the third-generation HSA series header is equipped with a reinforced closed-type chain drive, hydraulic control of the snapping plates, and a contour following system. These innovations contribute to increased efficiency and reliability of the header's operation.

Key Advantages:

• Minimal Cutting Height and High Harvesting Speed: The modern cutting unit and contour following system achieve minimal cutting height, increasing harvesting speed and making header operation easier.
• Efficient Chopping and Mowing: The placement of the chopping unit's cutting section ahead of the header's center allows efficient chopping of leaf-stalk mass and mowing up to 80% of weeds in the inter-rows.
• Well-Designed Pulling Rollers: The rollers are equipped with cutting knives to accelerate the composting process and protect against pests. The patented design prevents premature stalk cutting, avoiding threshing overload.
• Ease of Maintenance: The header is designed to provide easy access to components and minimize maintenance costs. The ability to switch the drive position from top to bottom allows flexible equipment adjustment for different conditions.

Technical Specifications:

• Productivity: up to 6.7 Ha/h
• Harvesting Speed: up to 12 km/h
• Minimum Ear Harvesting Height: 15 cm

Construction Features:

• Pulling Rollers: Have a square cross-section, equipped with knives and ribbed plates for cutting and pulling the stalk. Anti-cutting plates prevent fiber winding. Closed-type ball bearings do not require daily lubrication.
• Chopper Unit: Consists of a powerful horizontal cutting unit and two self-sharpening knives. The cutting unit is parallel to the rollers, ensuring high-quality chopping of the stalk mass.
• Reinforced Chain Drive: Utilizes a time-tested chain drive with a reinforced 25th single-row chain.
• Safety Friction Clutch: Installed on the drive shafts and the auger drive, requiring no daily maintenance.
• Row Dividers: Made of high-quality polyurethane and painted in the color of the combine upon prior request.
• Automatic Lubrication: Increases the lifespan of the drive chains and minimizes maintenance.
• Multicoupler: Ensures quick and efficient connection of the combine's hydraulic and electrical systems to the header. Hydraulic adjustment of the snapping plates is controlled from the combine's cab.
• Protective Canopy: Installed at the top of the header's intake window, preventing ear ejection.
• Extended Sides: Ensure smooth and loss-free direction of the stalk mass from the outer rows into the header.
• Stubble Wheel Protection (optional): Protects the combine's wheels from stubble punctures, easily mounted on the header.
• AutoContour System (optional): Allows efficient operation on complex terrains, automatically maintaining the set cutting height.
• Sunflower Harvesting Attachment (optional): Makes the header versatile, with a simple installation process that requires no special skills.
• Tilt Angle Adjustable Spacer (optional): Allows changing the attack angle for optimal header adjustment under different harvesting conditions.

The OROS 3 HSA header, with its technological innovations and reliability, ensures high productivity and cost efficiency. It is an excellent choice for modern farmers who aim to optimize their costs and increase yields.
