The T-278A post hole digger gearbox, crafted by TEBSA in Argentina, is a robust and reliable solution for agricultural and landscaping tasks requiring precise, powerful digging. Designed as a direct replacement for the Comer Code T-278A with a 1:1 gear ratio, this gearbox delivers exceptional performance for post hole diggers used in fencing, tree planting, and foundation work across Argentina’s diverse terrains, from the fertile Pampas to the rugged fields of Patagonia. Since 1997, TEBSA has built a legacy of manufacturing excellence, offering a 100% quality guarantee and a 50% cost advantage compared to original brands.

Built with cast iron GG25 housing, the T-278A ensures durability under heavy loads, making it ideal for demanding applications like soybean farm fencing or vineyard post installation. Its compact design, weighing just 23.5 kg, supports easy integration into various agricultural setups. The gearbox features a splined input shaft (Z) and dual 1 3/8" (6) output shafts (X and Z), ensuring seamless power transfer from the tractor’s PTO to the auger. With a maximum input power of 40.5 kW and an output torque of 693 Nm, it handles tough soils with ease, delivering consistent results for farmers and contractors.

TEBSA’s advanced manufacturing processes, including forging and precision grinding, enhance the gearbox’s strength and longevity. The T-278A is delivered without oil, allowing users to fill it with 80W-90 viscosity oil (up to 1.7 liters) tailored to their operating conditions. This flexibility, combined with TEBSA’s 24-hour engineering support, makes the T-278A a top choice for agricultural professionals seeking reliable post hole digger gearboxes in Argentina.

Maintenance and Technical Details

Proper care ensures the T-278A gearbox performs reliably for years. Here’s how to keep it in top shape:

Initial Oil Setup: The gearbox ships without oil. Fill it with 1.7 liters of 80W-90 viscosity oil before use. Replace the oil after the first 50 hours of operation to remove initial debris.

Regular Oil Checks: Change the oil every 500 hours or annually, whichever comes first. Check for contaminants regularly to maintain smooth gear performance.

Inspection Routine: Before each use, inspect the gearbox for leaks, cracks, or wear on the cast iron housing. Ensure the splined input shaft (Z) and output shafts (X and Z) are free of debris.

Alignment and Lubrication: Verify that the gearbox is properly aligned with the PTO shaft to prevent vibration or gear damage. Lubricate the input shaft periodically to ensure efficient power transfer.

Storage Tips: When not in use, store the gearbox in a dry, covered area to protect it from Argentina’s humid or rainy seasons, especially in regions like Entre Ríos.
