Flail Mower Gearboxes – Replacement of Comer Code L-5A 1:1.89
The Flail Mower Gearbox L-5A, crafted by TEBSA in Argentina, is a robust solution for powering flail mowers used in tough agricultural and landscaping tasks. Whether you're clearing overgrown pastures in the Pampas, maintaining orchards in Mendoza, or tackling roadside weeds in Buenos Aires, this gearbox delivers the strength and reliability you need. Since 1997, TEBSA has built a legacy of quality, offering a 100% guarantee on every order and cutting costs by up to 50% compared to original brands.

Its cast iron GG20 housing withstands the rigors of Argentina’s diverse terrains, while a 1:1.89 gear ratio ensures efficient performance.

- Estrutura robusta: Made from cast iron GG20, it’s forged and heat-treated to endure heavy loads and harsh conditions, like Argentina’s dusty plains or humid farmlands.
- Transferência de energia eficiente: The 1:1.89 gear ratio optimizes blade speed, making quick work of grass, weeds, or crop residue in soybean or wheat fields.
- Segurança em primeiro lugar: The integrated clutch prevents damage by stopping the blades during sudden stalls, keeping operators safe in demanding environments.
- Baixa manutenção: Simple upkeep, with oil changes after 50-70 hours initially and every 500 hours thereafter, keeps it running smoothly.

Aplicações e Benefícios na Agricultura Argentina
The L-5A flail mower gearbox is a versatile workhorse, tailored to meet the demands of Argentina’s agricultural and landscaping sectors. Its ability to handle tough tasks makes it a favorite among farmers and contractors. Here’s how it shines:
- Roçada Agrícola: Perfect for clearing crop residue in soybean or corn fields, the L-5A powers through dense vegetation with ease, ensuring fields in Córdoba or Santa Fe are ready for planting.

The L-5A’s benefits extend beyond its applications. Its cast iron GG20 construction, forged and heat-treated (via carburization), ensures it can handle the vibrations and shocks of heavy use. The 22.8 daNm maximum output torque delivers consistent power, while the 1:1.89 gear ratio balances speed and force for optimal cutting. The safety clutch adds a layer of protection, reducing downtime and repair costs. At just 7.7 kg, it’s lightweight yet sturdy, making it easy to install on various mower models.
For Argentine farmers, the L-5A’s 50% cost advantage over Comer gearboxes is a game-changer. It delivers high-end performance at a fraction of the price, backed by TEBSA’s ISO9001-2015 certification and 24-hour technical support. Whether you’re buying a flail mower gearbox online or equipping a fleet of mowers, the L-5A is a reliable, budget-friendly choice.
Dicas de manutenção e instalação
To keep the L-5A flail mower gearbox performing at its best, follow these practical steps:
1. Initial Setup: The gearbox ships without oil. Fill it with 0.4 liters of 80W-90 oil before use to ensure smooth operation.
2. Oil Changes: Change the oil after 50-70 hours of initial use, then every 500-700 hours or annually. Check for contaminants to maintain performance.
3. Inspeções regulares: Look for leaks, wear, or loose bolts, especially after heavy use in dusty or muddy conditions like Argentina’s rainy seasons.
4. Clutch Care: Test the safety clutch periodically to confirm it disengages properly, protecting both the gearbox and mower.
5. Alinhamento: Ensure the gearbox is properly aligned with the PTO shaft to avoid undue stress on gears.
For installation, the L-5A’s 25 mm shafts (X and Z) fit most standard flail mowers. Its compact design (gear arrangements 13-14 increasing, 1-2 reducing) simplifies mounting. If you need custom RPM settings, TEBSA’s engineering team can assist within 24 hours.
