Why Choose the LF-140J Rotary Mower Gearbox?

Rotary-Mower-Gearbox-Replacement-of-Comer-Code-LF-140J

The LF-140J rotary mower gearbox stands out for its blend of strength, versatility, and value, making it a top pick for agricultural professionals in Argentina. Here’s what sets it apart:

Robust Power Delivery: With a 1:1.93 gear ratio and 44 kW (60 HP) input power, the LF-140J drives mower blades with precision and force. It handles tough vegetation like overgrown grass or thick weeds, ensuring clean cuts in fields from Buenos Aires to Mendoza.

Durable Construction: Made with cast iron GGG40, a material known for its toughness, this gearbox resists wear from daily use. TEBSA’s advanced manufacturing—think forging, heat treatment like carburization, and precision grinding—means it can take on Argentina’s rugged terrains.

Wide Compatibility: The 6-spline input shaft (1 3/8") and 15-spline output shaft (ASA Z15 D.P. 8/16) fit most rotary mowers, from small farm units to heavy-duty models. This flexibility suits diverse setups across Argentina’s farms.

Cost Savings: At 50% less than original brands like Comer, the LF-140J offers premium performance without the premium price. TEBSA’s strategic sourcing and lean production keep costs low while maintaining quality.

Low Maintenance: Designed for ease, the gearbox needs an oil change after 50-70 hours initially, then every 500-700 hours. Using 80W-90 oil (1.4 liters), it’s simple to keep in top shape, minimizing downtime.

Local Reliability: Built with Argentina’s farmers in mind, the LF-140J thrives in soybean fields, wheat pastures, or grassy plains. TEBSA’s team responds within 24 hours to any questions, ensuring you’re never stuck.

Applications of the LF-140J in Argentine Agriculture

The LF-140J rotary mower gearbox is a workhorse for Argentina’s agricultural sector, where diverse crops and landscapes demand reliable equipment. Its primary role is powering rotary mowers, which slice through grass, weeds, and crop residue with ease. Here’s how it fits into local farming:

Pasture Management: In regions like Córdoba or Santa Fe, where cattle grazing is big, the LF-140J keeps pastures tidy. It powers mowers to clear overgrown grass, promoting healthy regrowth for livestock.

Crop Residue Clearing: After harvesting soybean, wheat, or corn, fields often need cleaning. The LF-140J’s torque (39 daNm output) handles tough stalks and debris, prepping land for the next planting season.

Roadside and Public Maintenance: Beyond farms, the gearbox suits municipal tasks in cities like Rosario or Mendoza. It drives mowers to maintain parks, highway medians, and sports fields, ensuring neat, safe spaces.

Rotary-Mower-Applications

Small and Large Farms: Its compatibility with various mowers makes it ideal for both family-run farms and large agribusinesses. Whether you’re cutting a few hectares or hundreds, the LF-140J delivers consistent results.

This gearbox is built for Argentina’s unique conditions—think dusty plains, humid summers, and uneven fields. Its cast iron housing shrugs off impacts from rocks or debris, while the spline shafts ensure smooth power transfer from tractor PTOs. For farmers buying rotary mower gearboxes online, the LF-140J is a dependable choice that balances performance and affordability.

Maintenance and Installation Tips for the LF-140J

To get the most out of your LF-140J rotary mower gearbox, proper setup and care are key. TEBSA designs it for ease, but a few steps ensure it runs smoothly for years:

Installation: The gearbox arrives without oil, so fill it with 1.4 liters of 80W-90 oil before use. Check that the 6-spline input shaft aligns with your tractor’s PTO and the 15-spline output shaft matches your mower. Secure all bolts tightly and verify alignment to avoid vibrations.

First Use: Run the mower lightly for a few minutes to let the oil circulate. After 50-70 hours, drain and replace the oil to remove any initial debris from break-in.

Regular Maintenance: Change the oil every 500-700 hours or annually, whichever comes first. Inspect the gearbox for leaks, cracks, or wear on the spline shafts. Clean the input shaft and apply fresh grease to prevent corrosion, especially in Argentina’s humid climates.

Storage: If the mower sits idle during off-seasons, store the gearbox in a dry place. Drain the oil to avoid sludge buildup, and coat exposed metal with a rust inhibitor.

Troubleshooting: If you notice unusual noises or reduced power, check oil levels and shaft alignment. TEBSA’s engineering team responds within 24 hours to help with any issues.

By following these tips, you’ll keep the LF-140J in top shape, minimizing repairs and maximizing uptime. Its design supports quick maintenance, so you can focus on farming, not fixing.
