Lightweight yet sturdy, this aluminium gearbox delivers efficiency for tillers, mowers, and more, thriving in Argentina’s diverse fields—from soybean farms in Córdoba to wheat fields in the Pampas.

Built for multi-row rotary tillers, band saws, and various agricultural applications, the T-281J handles tough jobs with ease. Its smart design balances power and precision, using advanced forging and machining processes like teeth grinding and heat treatment for lasting strength. Whether you’re prepping soil for planting or maintaining pastures, this gearbox keeps your equipment running smoothly, backed by TEBSA’s 24-hour support team.

Key Features and Technical Specifications

The T-281J rotary tiller gearbox combines versatility and toughness, making it a go-to choice for Argentine farmers and beyond. Its aluminium housing keeps weight low at just 7 kg, while delivering a max output torque of 29.4 daNm—ideal for demanding tasks like soil tillage or mowing. With gear ratios of 1:1.46 (increasing) and 1.46:1 (reducing), it adapts to different equipment needs, ensuring optimal performance whether you’re powering a tiller or a band saw.

This gearbox arrives without oil, giving you control to fill it with 80W-90 SAE viscosity oil (up to 0.5 liters). For first-time use, change the oil after 50 hours to keep it running like new, then every 500 hours thereafter. The input shaft (X) and output shaft (Z) both measure 1 3/8" (6 splines), ensuring compatibility with standard PTO setups on tractors across Argentina.

Our engineering team at TEBSA is ready to answer questions about performance at different speeds—especially useful for fine-tuning your setup for crops like corn or soybeans. The gearbox’s gear arrangements (23-24 for increasing, 3-4 for reducing) provide flexibility, with input power ratings of 14.7 kW/20 HP (increasing) and 11.8 kW/16 HP (reducing).

Applications and Benefits for Argentine Agriculture

The T-281J rotary tiller gearbox is a versatile workhorse, built to tackle a range of tasks that Argentine farmers face daily. It powers multi-row rotary tillers, slicing through compacted soil to prepare seedbeds for crops like wheat, soybeans, or sunflowers in regions like Buenos Aires or Santa Fe. For smaller operations, it drives mowers to keep pastures tidy, while industrial users rely on it for band saws cutting materials with precision.

Why choose TEBSA’s T-281J? First, it’s efficient—delivering steady power from your tractor’s PTO to the tiller blades, saving time on big jobs. Second, its aluminium housing resists corrosion, a must for Argentina’s humid summers or dusty dry seasons. At only 7 kg, it won’t weigh down your equipment, yet it handles up to 29.4 daNm of torque, enough for tough clay soils in the Pampas.

Safety matters too. The T-281J’s precise machining—think teeth hobbing and grinding—ensures smooth operation, cutting down on vibrations that could strain your tractor. Plus, it’s easy to maintain. Just fill it with 80W-90 oil, swap it after 50 hours of initial use, and check it every 500 hours. That’s less downtime and more fieldwork.

For Argentine buyers, TEBSA’s 50% cost advantage makes the T-281J a smart pick over pricier originals. You get the same performance—whether tilling fields near Rosario or mowing grass in Mendoza—without breaking the bank. Our 100% quality guarantee means every gearbox is tested to ISO9001-2015 standards, so you’re covered for the long haul.

Looking for a rotary tiller gearbox for sale online? The T-281J fits the bill, whether you’re upgrading a multi-row tiller or replacing a worn-out unit. Its compatibility with 1 3/8" PTO shafts makes it a seamless fit for most tractors in Argentina, from small farms to large agribusinesses.

Maintenance Tips and Best Practices

Keeping the T-281J rotary tiller gearbox in top shape is straightforward, ensuring it lasts through years of planting seasons. Start by filling it with 0.5 liters of 80W-90 oil before use—since it ships dry, this step’s on you. After the first 50 hours, drain and refill to clear out any break-in debris. From there, check the oil every 500 hours or once a season, whichever comes first.

Regular checks are key. Look for leaks around the seals, especially after heavy tilling in wet soils like those near the Paraná River. Clean the input shaft (X) and output shaft (Z) to prevent dirt buildup, which can wear down splines over time. If you’re running the gearbox at high speeds—say, for mowing versus tilling—double-check alignment to avoid excess heat or gear strain.

Got questions about RPM settings or torque for specific crops? TEBSA’s team responds within 24 hours, helping you dial in the T-281J for tasks like turning over sunflower stubble or prepping cornfields. Our forging and heat treatment processes—like carburization—mean the gears can handle Argentina’s tough conditions, but proper care keeps them spinning smoothly.

For buyers searching “reliable rotary tiller gearbox in Argentina,” maintenance ease is a big draw. Unlike heavier cast iron models, the T-281J’s aluminium body resists rust, a win for humid areas like Misiones. And with a max torque of 29.4 daNm, it’s got the muscle for deep tillage without needing constant repairs.

By sticking to these steps, you’ll keep the T-281J running strong, whether you’re tilling clay soils in La Pampa or mowing grass in Chaco. It’s a low-hassle gearbox built for real-world farm life.
