Key Features and Technical Specifications

The T-25J rotary mower gearbox is a versatile component tailored to meet the needs of Argentina’s agricultural and industrial sectors. Its aluminum construction balances strength and weight, reducing strain on equipment while ensuring long-term reliability. The gearbox supports both speed-increasing (1:1.9) and reducing (1.9:1) ratios, making it adaptable for tasks requiring different power outputs, such as mowing dense grass or powering band saws for woodworking.

TEBSA’s manufacturing expertise shines in the T-25J’s design. Using alloy steel gears and precision machining, we achieve a maximum output torque of 22.7 daNm, suitable for demanding applications like chemical fertilizer spreading in Argentina’s soybean fields. The gearbox arrives without oil, allowing users to fill it with 0.35 liters of 80W-90 viscosity oil, with a recommended change after 50 hours of initial use and every 500 hours thereafter. At just 4.1 kg, it’s easy to install and handle, minimizing downtime on farms or job sites.

For those seeking a reliable rotary mower gearbox in Argentina, the T-25J’s technical specs make it a standout. Its dual shaft options (X and Z) ensure compatibility with various PTO-driven equipment, from mowers to spreaders. Farmers in Buenos Aires or industrial operators in Mendoza can rely on its performance, backed by TEBSA’s ISO9001-2015 certification for quality assurance.

Applications and Benefits in Argentine Agriculture

The T-25J gearbox is a workhorse for Argentina’s diverse agricultural landscape. It powers rotary mowers slicing through thick pastures for cattle grazing, supports fertilizer spreaders preparing soil for corn and wheat, and even drives band saws in rural workshops. Its versatility suits both small farms and large-scale operations, making it a go-to for tasks across Argentina’s fertile regions.

In the Pampas, where soybean and corn dominate, the T-25J ensures mowers cut cleanly, boosting efficiency during tight harvest windows. Its 11 kW/15 HP input for speed-increasing tasks handles high-speed mowing, while the 7 kW/9.5 HP reducing mode suits slower, torque-heavy jobs like spreading fertilizer. The aluminum housing resists corrosion from Argentina’s humid summers, and the lightweight design eases installation on older tractors common in rural areas.

Key benefits include:

• Efficiency Boost: Smooth power transfer cuts down on fuel and time, critical for farmers in Córdoba managing large plots.
• Cost Savings: At 50% less than original Comer models, it’s a budget-friendly upgrade without sacrificing quality.
• Durability: Forged gears and heat-treated components stand up to rocky soils and heavy loads.
• Flexibility: Dual ratios let you switch between tasks like mowing and spreading without swapping gear.
• Easy Maintenance: Simple oil changes and accessible parts keep downtime low, with TEBSA’s support just a call away.

For online buyers searching “buy rotary mower gearbox in Argentina,” the T-25J delivers value and reliability. Its compact size fits tight spaces on equipment, and the lack of pre-filled oil lets users choose the right lubricant for local conditions, like the dusty fields of Santa Fe.

Whether you’re clearing land for cattle or prepping fields for planting, this gearbox adapts to your needs with precision and power.

Maintenance and Installation Tips

Keeping the T-25J in top shape is straightforward, ensuring it serves your farm or workshop for years. Start by filling it with 0.35 liters of 80W-90 oil before use, as it ships dry to avoid leaks during transport. After the first 50 hours, drain and refill to clear any break-in debris. From there, change the oil every 500 hours or annually, whichever comes first, to maintain smooth operation in Argentina’s variable climates.

Installation is quick thanks to the T-25J’s lightweight 4.1 kg frame and standard shaft sizes (1 3/8" for X, 22 mm for Z). Match the shaft to your PTO setup, and double-check alignment to avoid wear. If you’re swapping out a Comer T-25J, the dimensions align perfectly, making it a plug-and-play replacement for mowers or spreaders. For band saws, ensure the input power doesn’t exceed 11 kW to protect the gears.

Regular checks keep problems at bay:

Look for leaks or dents around the housing, especially after heavy use.

Listen for unusual noises, which could signal misalignment.

Grease the input shaft yearly to ease PTO connection.
