⭐ Características clave y ventajas de ingeniería

🚀

Through-Hardened Spur Gear Train

HRC 56-60 alloy steel spur gears designed for the high-impact reversing loads encountered during aggressive rotary tiller soil engagement.

💪

3× Peak Torque Output Capacity

Oversized output shaft rated for transient torques three times nominal, absorbing the repeated shock loads when tiller blades strike buried rocks and roots.

⚙

500-Hour Extended Oil Intervals

Large sump capacity with high-grade EP oil enables 500-hour drain intervals, reducing maintenance frequency during the busiest planting and cultivation seasons.

⚗

Oil-Bath Splash Lubrication

Generous sump with directional baffles ensures all gear teeth and bearing races are oil-wetted at all times, even at the lowest recommended operating speed.

🔒

Magnetic Drain Plug

Neodymium drain plug captures ferrous wear particles from break-in and normal operation, protecting gears and bearings from abrasive recirculation damage.

⚡

High-Capacity Oil Sump Design

30% larger oil volume compared to standard models, reducing operating temperature by 8-12 °C during sustained high-load mowing and extending lubricant life.

📚 Guía de selección de cajas de cambios

Proper gearbox selection protects your investment and maximizes field productivity. Here is how to determine if the EP-40002 is right for your operation:

📌 Selección de toma de fuerza (PTO) de 540 RPM frente a 1000 RPM
The EP-40002 operates at 540 rpm. Most rotary mowers use 540 RPM PTO. The 1000 RPM standard is for larger implements on high-HP tractors. Never connect a 540 RPM gearbox to a 1000 RPM PTO — the doubled speed will destroy bearings and gears within minutes.
📌 Cast Iron Housing vs Aluminium Housing
The EP-40002 uses a ductile cast iron housing. Cast iron excels in vibration damping, impact resistance, and heat dissipation — ideal for rough, rocky mowing conditions. Aluminium is lighter and more corrosion-resistant, better suited to wet environments and weight-sensitive implements.
📌 Standard Catalog vs Custom Specification
The EP-40002 is available as a standard catalog item shipping in 3-5 days. If your application requires a non-standard ratio, shaft type, or mounting configuration, our engineering team offers custom designs with 4-6 week lead times. Minimum order quantities may apply.
📌 Compatibilidad con el tipo de eje de salida
The EP-40002 features 1 3/4 Z6 output. Verify your blade hub or implement rotor accepts this shaft type before ordering. We offer multiple output configurations — spline, taper, keyway, and flange — to match virtually any existing installation.
📌 Consideraciones sobre el peso y el montaje
At 111 Kg, the EP-40002 is designed for industrial-grade vegetation management equipment. Confirm your implement frame and three-point hitch can support this weight plus the weight of the blade assembly. Mounting bolt pattern and orientation should match your existing layout.

🛠 Guía de instalación y configuración

  1. Apply a thin, even bead of RTV silicone sealant to the mounting flange face if a pre-cut gasket is not included with the new gearbox.
  2. Connect the PTO drive shaft to the gearbox input spline. Push the shaft on fully and verify it telescopes freely through the complete range of three-point hitch travel.
  3. After the first 10 hours of operation, re-torque all mounting bolts to specification and verify oil level. Perform the first oil drain and refill at 50 hours.
  4. Disconnect the tractor PTO shaft and safely support the mower implement on jack stands or blocks before beginning the gearbox installation procedure.
  5. For units weighing over 25 kg, use a chain hoist, engine crane, or two-person lift to position the gearbox. Never attempt to lift heavy gearboxes solo.
  6. Fill the gearbox with the recommended gear oil (SAE 80W-90 or 85W-140 EP) to the level indicated on the sight glass or dipstick. Do not overfill.
  7. Before operating at full load, run through a graduated break-in sequence: 30 minutes at half-throttle, then 30 minutes at three-quarter throttle, before engaging full PTO speed.

❓ Preguntas frecuentes

❓ Can I replace just the gear set?

Yes. Replacement gear sets are available for all models and are cost-effective when the housing, bearings, and shafts remain in good condition. We recommend replacing bearings and seals simultaneously for best results.

❓ Can this gearbox handle reverse PTO rotation?

Our spiral bevel designs operate correctly in both rotational directions without modification. However, check your specific implement requirements, as some mower blade assemblies are direction-sensitive.

❓ What maintenance checks should I perform regularly?

Before each use: check oil level, inspect for leaks. Every 50 hours: grease external fittings if equipped. Every 200 hours: change oil, inspect seals and bearings. Annually: open casing and visually inspect gear tooth surfaces for pitting or wear.

❓ ¿Puedo comprar piezas de repuesto individuales?

Sí. Disponemos de un inventario completo de repuestos (juegos de engranajes, rodamientos, juntas, ejes y tornillería) para todos los modelos que fabricamos. Realizamos envíos a todo el mundo y la mayoría de los artículos en stock se envían en un plazo de 24 horas.

❓ ¿Proporcionan planos dimensionales?

Disponemos de planos técnicos completos —con información sobre orificios de montaje, especificaciones del eje y dimensiones— para cada modelo. Puede descargarlos desde nuestras páginas de productos o solicitarlos gratuitamente a nuestro departamento técnico.

⭐ Opiniones de clientes e informes de campo

★★★★★

📍 Tasmania, Australia

Installed on a mulching mower that sees 8+ hours of use per day during season. Absolutely dependable. That is all I ask of a gearbox.

★★★★★

📍 Alentejo, Portugal

We maintain 40+ mowers for council contracts. Switching to this brand has reduced our gearbox failure rate by over 60 percent.

★★★★★

📍 Canterbury, Nueva Zelanda

Running in extreme cold (-25 °C) winters and hot summers. Synthetic oil in this gearbox handles both extremes without issue.

★★★★☆

📍 Krasnodar, Rusia

We replaced three OEM gearboxes with this model across our fleet. Gear quality and seal performance are noticeably superior. Reordering for next season.

★★★★☆

📍 Emilia-Romagna, Italy

Third year of heavy use on our hay field cutting. Still going strong with just regular oil changes. The best aftermarket gearbox I have found.
