Consejos de mantenimiento para un rendimiento duradero
To keep the T-312A flail mower gearbox running smoothly, follow these practical steps, backed by TEBSA’s expertise:
Fill Before Use: The gearbox ships without oil. Add 1.5 liters of 80W-90 oil before starting, checking for leaks after filling.
Regular Oil Changes: Swap the oil after 50-70 hours of initial use, then every 500-700 hours or yearly. Clean oil keeps gears and bearings in top shape.
Inspect for Wear: Check the housing and shafts for cracks or wear, especially after heavy use in rocky areas like Patagonia.
Lubricate Shafts: Grease the input and output shafts to ensure smooth power transfer and prevent corrosion.
Check Alignment: Misaligned mowers can stress the gearbox. Ensure the PTO and mower are properly lined up to avoid vibrations.
These steps help extend the gearbox’s life, saving you costly repairs. TEBSA’s team is ready to answer maintenance questions within 24 hours, ensuring you’re never stuck.
