Key Features and Technical Advantages
The TEBSA combine harvester reversing gearbox is crafted to meet the rigorous needs of modern agriculture, particularly in Argentina’s crop-heavy regions. Its standout features include:
- High-Strength Materials: The gearbox uses QT450 cast iron for its housing, offering exceptional resistance to wear and impact. The gear shaft, made from 20CrMnTi, undergoes carburization and heat treatment for added toughness, ensuring it withstands the heavy loads of rice or wheat harvesting.
- Ingeniería de precisión: Advanced manufacturing processes, like gear grinding and teeth hobbing, ensure smooth operation and minimal friction. This precision reduces energy loss, making the gearbox a reliable choice for long hours in the field.
- Seamless Reverse Functionality: Robust bearings and gears allow quick, jerk-free shifts between forward and reverse, critical for clearing blockages in dense crops like rice in Argentina’s Entre Ríos province.
- Diseño personalizable: Available in various colors and adaptable to different harvester models, it fits seamlessly into your equipment, whether for small rice fields or vast soybean farms.
- Bajo mantenimiento: Designed for easy upkeep, the gearbox supports replaceable seals and straightforward lubrication checks, backed by TEBSA’s 24-hour technical support.
The technical specs reflect TEBSA’s commitment to quality. The EP-1.6Z.03-05 model is optimized for rice harvesters, with a compact design that minimizes drivetrain stress. Its durability and efficiency make it a go-to for farmers aiming to maximize uptime during Argentina’s busy harvest seasons.

Aplicaciones en la agricultura argentina
The TEBSA reversing gearbox is a game-changer for combine harvesters operating in Argentina’s diverse agricultural landscape. Its primary role is enabling reverse motion to clear jams caused by tangled crops, a common issue in rice paddies or wheat fields. This functionality is critical in regions like Santa Fe, where rice farming thrives, or the Pampas, known for soybean and corn.
- Rice Harvesters: The EP-1.6Z.03-05 model excels in rice harvesting, where wet, dense stalks often clog machinery. Its quick reverse action minimizes downtime, keeping operations on track.
- Wheat and Soybean Fields: In Argentina’s breadbasket, the gearbox supports heavy-duty harvesters tackling vast fields, ensuring smooth cutting and threshing even under high loads.
- Safety and Efficiency: By reducing the need for manual jam clearing, it lowers risks for operators and boosts field productivity, a key factor for large-scale farms.
- Versatile Integration: Compatible with various combine harvester brands, it’s a flexible solution for farmers upgrading or maintaining their fleets.
Beyond rice, the gearbox supports other crops like corn and sorghum, making it a versatile tool for Argentina’s agribusiness. Its ability to handle continuous operation suits the long harvest seasons, while TEBSA’s cost-effective pricing—50% less than competitors—makes it accessible for local farmers.
Por qué es importante en Argentina
Argentina’s agriculture relies on efficient machinery to stay competitive globally. The reversing gearbox addresses common pain points like equipment jams, which can halt work and raise costs. By integrating this component, farmers in Buenos Aires or Mendoza can maintain steady workflows, even in challenging conditions like humid rice fields or dusty wheat plains.
Consejos de mantenimiento y longevidad
To keep the TEBSA reversing gearbox performing at its best, regular care is essential. Here’s how to ensure its longevity:
- Inspeccionar regularmente: Check for leaks, wear, or loose bolts every 50 hours of use, especially during peak harvest seasons.
- Lubricación: Use high-quality gear oil recommended by TEBSA, checking levels monthly and replacing every 500 hours or as needed.
- Clean Components: Clear debris from the housing and shaft to prevent buildup, particularly after working in muddy rice fields.
- Alignment Check: Ensure the gearbox aligns with the drivetrain to avoid uneven wear or vibrations.
- Professional Support: TEBSA’s engineering team responds within 24 hours for troubleshooting or part replacements.
These steps, combined with TEBSA’s ISO9001-2015 certified manufacturing, guarantee a gearbox that lasts through years of heavy use. The use of QT450 and 20CrMnTi, processed with techniques like carbonitriding, further enhances its resistance to Argentina’s demanding field conditions.
