Rotary Mower Gearbox – Replacement of Comer Code TF-26A
The TF-26A rotary mower gearbox, crafted by TEBSA in Argentina, is a vital component for rotary lawn mowers, seamlessly transferring power from the engine to the cutting blades. Designed for precision and durability, this gearbox ensures your mower tackles grass, weeds, and tough vegetation with ease.

Why the TF-26A Gearbox Excels in Mowing Applications
The TF-26A rotary mower gearbox is engineered to deliver top performance across a range of mowing tasks, making it a go-to choice for agricultural and landscaping needs in Argentina. Here’s why it stands out:
Enhanced Cutting Power: The gearbox’s gear system converts high engine speed into torque, giving blades the strength to cut through dense grass, weeds, or even small shrubs. With torque outputs of 615 Nm or 770 Nm (depending on the ratio), it handles tough jobs like clearing overgrown fields or maintaining public parks.
Adaptable Design**: Offering gear ratios of 1.47:1 and 1.84:1, the TF-26A lets operators adjust mowing speed to suit different conditions. For instance, a lower ratio works well for thick grass in humid regions like Misiones, while a higher ratio suits lighter lawns in urban Córdoba.
Durable Construction: Made from alloy steel with processes like carburization and grinding, the TF-26A resists wear and tear. Its sealed bearings and robust housing protect against dust and moisture—common challenges in Argentina’s varied climates.
User-Friendly Features: An optional clutch allows quick blade engagement or disengagement, improving safety during operation. The hub connection simplifies installation, saving time for farmers in busy seasons like soybean planting.
Cost Savings: At 50% less than comparable original models, TEBSA’s TF-26A delivers premium performance without the premium price. This makes it ideal for small farms or landscaping businesses looking to maximize value.
The TF-26A shines in applications like pasture maintenance, roadside mowing, and vineyard upkeep. Its versatility ensures it meets the needs of Argentina’s diverse agricultural landscape, from wheat fields in Santa Fe to orchards in Mendoza.
Technical Features and Material Breakdown
To give you a clearer picture of what makes the TF-26A reliable, here’s a detailed look at its construction and capabilities:
Feature | Details |
---|---|
Primary Material | Alloy Steel (carburized for extra strength) |
Housing | Cast Iron (blackened for corrosion resistance) |
Bearings | Sealed, High-Precision Ball Bearings |
Gear Type | Spur Gears (precision-ground) |
Torque Range | 615–770 Nm |
Input Speed | 540 RPM |
Shaft Compatibility | 1'' 3/8 Z6 (X, Y); Hub Connection (Z) |
The alloy steel gears undergo carburization to harden their surfaces, ensuring they withstand heavy loads without cracking. The cast iron housing, treated with blackening, resists rust—a must for Argentina’s humid summers. These choices reflect TEBSA’s focus on quality, honed over nearly three decades of manufacturing.
For technical buyers, the TF-26A’s 66 kW power rating and dual gear ratios offer flexibility. Whether you’re mowing a golf course or a rural pasture, the gearbox delivers consistent performance. Its compact size also reduces strain on the mower’s frame, extending the life of your equipment.
Applications and Maintenance for Long-Term Performance
The TF-26A rotary mower gearbox is a workhorse across Argentina’s agricultural and landscaping sectors. Here are its key applications and tips to keep it running smoothly:
Pasture Management: Ideal for cutting grass to promote healthy grazing in cattle-heavy regions like La Pampa.
Roadside Mowing: Powers mowers that clear highways or rural roads, handling uneven terrain with ease.
Orchard and Vineyard Care: Trims grass between rows, supporting crops like grapes in Mendoza or apples in Río Negro.
Urban Landscaping: Perfect for parks and sports fields in cities like Rosario, delivering a clean cut every time.
To maximize the TF-26A’s lifespan, follow these maintenance steps:
Check Oil Regularly: Use manufacturer-approved lubricant and top off the 0.5L reservoir as needed to prevent gear wear.
Inspect Seals: Look for leaks around the shaft to avoid dirt entering the gearbox.
Clean After Use: Remove grass or debris to prevent corrosion, especially after wet conditions.
Monitor Alignment: Ensure the gearbox and blades are properly aligned to reduce vibration.
Schedule Inspections: Have TEBSA’s team review the unit annually for wear on bearings or gears.
Regular care keeps the TF-26A performing like new, saving you downtime and repair costs. Its design makes maintenance straightforward, so even small farms can handle upkeep without specialized tools.
