The LF-205 lawnmower gearbox, engineered by TEBSA in Argentina, is a reliable choice for powering rotary cutters and lawnmowers in tough mowing jobs. Whether you’re maintaining vast lawns, clearing overgrown pastures, or tackling roadside vegetation, this gearbox delivers steady performance. With a gear ratio of 1:1.92, it’s built to handle 30 horsepower at 540 RPM, featuring a counterclockwise (CCW) rotation. The input shaft measures 1-3/8" with 6 splines, while the 12-spline output shaft uses tapered splines—note that the bushing (part A-U920580500 or U0135700000) is sold separately. Its mounting pattern is a solid 171.5 mm, making it a perfect fit as a replacement for Comer rotary cutters.

Since 1997, TEBSA has crafted durable agricultural gearboxes, and the LF-205 is no exception. Designed with high-strength materials like alloy steel and finished with advanced processes such as forging and heat treatment, it stands up to Argentina’s demanding farming conditions—think Pampas grasslands or soybean fields. At 50% less cost than original brands, it’s a smart pick for farmers, landscapers, and equipment dealers looking for quality without breaking the bank.

Installation, Maintenance, and Why Choose TEBSA

Installing the LF-205

Setting up the LF-205 is straightforward if you’ve got the right parts. The 1-3/8" 6-spline input hooks up to your tractor’s PTO, while the 12-spline output needs the separate bushing (A-U920580500 or U0135700000) for a tight fit. Bolt it onto the 171.5 mm mounting points, and you’re ready to roll. Tip: Double-check alignment to avoid strain on the gears.

Maintenance Tips

Keep the LF-205 running smoothly with these steps:
- Oil Checks: Use high-quality gear oil and check levels every 50 hours of use. Top off or replace as needed.
- Grease the Shafts: Lubricate the input and output splines to cut down on friction.
- Inspect Regularly: Look for leaks or wear, especially after heavy mowing sessions.
- Store Smart: Keep it dry and covered when not in use to protect the alloy steel from rust.

With proper care, this gearbox will serve you for years, backed by TEBSA’s 100% quality guarantee.
