Consejos de mantenimiento e instalación
To keep the L-5A flail mower gearbox performing at its best, follow these practical steps:

2. Cambios de aceite: Change the oil after 50-70 hours of initial use, then every 500-700 hours or annually. Check for contaminants to maintain performance.
3. Inspecciones periódicas: 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. Alineación: 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.
