Key Specifications of the EP-1ZS-380 Lawn Mower Gearbox

This gearbox is engineered for performance, delivering 100 HP of power at a 540 RPM input. Its spline input/output design ensures smooth power transfer, while a 1:1.24 ratio and 21/17/17/17 teeth configuration provide the torque needed for heavy-duty mowing. Weighing 42.5 kg, it’s sturdy yet manageable for various setups.

Design and Applications of the EP-1ZS-380 Lawn Mower Gearbox

The EP-1ZS-380 isn’t just another agricultural gearbox—it’s a workhorse built for real-world demands. Whether you’re a farmer in Argentina’s Pampas cutting grass for livestock or a landscaper shaping lawns in Buenos Aires, this gearbox delivers. It’s perfect for lawn mowers, brush cutters, and even light rotary tillers, thanks to its versatile spline design and 100 HP capacity.

Common Uses: Think pasture maintenance, roadside clearing, or large lawn care jobs. In Argentina, where soybean and wheat fields dominate, it’s also handy for keeping edges tidy or prepping land between harvests. The 1:1.24 gear ratio balances speed and torque, making it a go-to for medium to heavy-duty tasks without overloading your tractor’s PTO.

Material Strength: We use alloy steel for the gears, treated with processes like carburization and grinding to resist wear. The housing? Tough cast iron, ready to take on vibrations and knocks from rocky fields. This isn’t a lightweight throwaway—it’s built to handle years of hard work.

Why It Works: The spline input/output setup locks in tight with your PTO shaft, cutting down on slippage and boosting efficiency. At 540 RPM, it’s matched to most standard tractors in Argentina, so you won’t need extra adapters or tweaks. Plus, at 42.5 kg, it’s solid but won’t weigh down your rig.

Technical Features and Performance Edge

What sets the EP-1ZS-380 apart? It’s all in the details. The 21/17/17/17 teeth setup, with a 7.0 module, means precision-cut gears that mesh smoothly and hold up under load. That 1:1.24 ratio isn’t random—it’s calculated to give you just enough spin to cut cleanly without bogging down your engine.

Power Delivery: Rated at 100 HP, this gearbox can take on bigger mowers or tougher jobs than lighter models. Farmers in Córdoba or Santa Fe, dealing with dense grass or scrub, will notice the difference. The spline connection keeps power flowing from tractor to blades with minimal loss—something you’ll feel in faster cuts and less fuel burn.

Built to Last: We don’t skimp on quality. The alloy steel gets heat-treated for extra hardness, while the cast iron shell shrugs off impacts. Processes like teeth grinding and surface blackening add years to its life, even in Argentina’s humid summers or dusty harvests.

Easy Fit: Got a 540 RPM PTO? You’re set. The spline design is standard across many tractor brands, so swapping it in is straightforward. And at 42.5 kg, it’s hefty enough to stay stable but light enough to handle during installs.

Long-Tail Advantage: Looking for a “reliable lawn mower gearbox for sale in Argentina”? This is it. Need a “100 HP agricultural gearbox for pasture mowing”? Same answer. TEBSA’s engineering team—on call within 24 hours—backs every unit, so you’re never stuck troubleshooting alone.
