Why Choose the LF-149B for Your Mower?

The LF-149B rotary mower gearbox stands out for its balance of strength, efficiency, and affordability, making it a favorite among Argentine farmers and landscapers. Here’s what sets it apart:

Reliable Power Transfer: With a 1:1 gear ratio and up to 47 kW of input power, it delivers steady force to the blades, cutting through dense grass or weeds without strain. This makes it ideal for maintaining pastures or clearing land for crops like soybean and wheat.

Tough Build: The cast iron GGG40 housing and steel gears, forged and heat-treated for extra resilience, ensure it can handle Argentina’s varied terrains—from muddy lowlands to dry plains. TEBSA’s advanced manufacturing, honed since 1997, guarantees a gearbox that lasts.

Easy Fit: Its standard threaded output shaft pairs with most rotary mowers, so you can swap it in without hassle. Whether you’re in Buenos Aires or Mendoza, installation is quick, saving you downtime.

Low Upkeep: Designed for minimal maintenance, it only needs an oil check after 50-70 hours initially, then every 500 hours. Use 80W-90 oil, and you’re set for reliable performance season after season.

Cost-Smart: At 50% less than original Comer models, the LF-149B offers top-tier quality without breaking the bank. It’s a practical choice for farmers watching their bottom line.

Applications in Argentine Agriculture

The LF-149B rotary mower gearbox thrives in Argentina’s diverse farming landscape. It’s built to power mowers that keep fields tidy and productive, supporting crops like soybean, wheat, and corn—key to the nation’s economy. Here’s where it shines:

Pasture Management: In the Pampas, where grazing lands stretch wide, the LF-149B helps mow grass to promote healthy regrowth for cattle. Its 81 daNm output torque cuts through thick patches effortlessly.

Crop Residue Clearing: After harvests in Córdoba or Santa Fe, it powers mowers to chop down stalks, preparing fields for the next planting. The gearbox’s durability handles dusty, debris-filled conditions.

Landscaping and Estates: For rural properties or public spaces in Buenos Aires, it keeps lawns neat. The lightweight 33.4 kg design makes it easy to maneuver on smaller mowers.

Orchards and Vineyards: In Mendoza’s wine country, it trims grass between rows, ensuring clean pathways without stressing the mower’s engine.

This versatility makes the LF-149B a staple for farmers, landscapers, and contractors across Argentina. Its compatibility with standard PTO shafts (1 3/8" Z-21) means it fits seamlessly into existing setups, whether on a tractor-driven mower or a smaller unit for precision work.

Maintenance and Installation Tips

Keeping the LF-149B in top shape is straightforward, ensuring it serves your mower for years. TEBSA’s design prioritizes ease, backed by our 24-hour support team. Here’s how to maintain and install it:

Installation: Bolt it onto your mower’s deck, aligning the threaded output shaft with the blade assembly. Connect the input shaft (Z-type) to the PTO. Double-check alignment to avoid vibrations. Most users in Argentina find it takes under an hour, even on older mowers.

Oil Management: The gearbox ships without oil, so fill it with 0.8 liters of 80W-90 SAE oil before use. Change the oil after 50-70 hours of initial mowing, then every 500 hours or yearly. This keeps gears running smoothly, especially in dusty conditions like Santa Fe’s fields.

Regular Checks: Inspect for leaks or wear every few months, particularly after heavy use in soybean harvests. Tighten bolts and clean the housing to prevent debris buildup.

-Storage: If you’re storing the mower off-season, drain the oil and keep the gearbox in a dry spot to avoid rust—a common concern in Argentina’s humid summers.

For any questions, TEBSA’s engineers are ready to help within a day, whether you’re in Mendoza or Rosario. This low-maintenance design saves you time and money, letting you focus on the field.
