⭐ Características clave y ventajas de ingeniería

🔬

18CrNiMo7-6 Aerospace Gear Steel

Vacuum-carburized gears from aircraft-grade alloy achieve HRC 60-63 surface and a tough pearlitic core, meeting AGMA Class 10 tooth accuracy standards.

⚖

98%+ Power Delivery Efficiency

Mirror-polished flanks (Ra ≤ 0.4 μm) and AGMA Class 11 accuracy virtually eliminate parasitic losses, ensuring every horsepower reaches the cutting blade.

🚀

4140 Chrome-Moly Output Flange

Forged steel output flange heat-treated to HRC 28-32, drilled for heavy-duty blade carriers up to 50 kg — eliminating the flex found in cast alternatives.

💪

GGG-60 Heavy-Plate Housing

EN-GJS-600-3 ductile iron with 18 mm walls and FEA-optimized ribbing, engineered for sustained 150+ HP loads without measurable housing flex.

⚙

Pressurized Internal Oil Pump

Gear-driven micro-pump maintains positive lubrication pressure at all critical contacts, enabling safe operation on slopes exceeding 40° without oil starvation.

⚗

Lightweight AlSi7Mg T6 Housing

Aluminum-silicon alloy housing with T6 temper provides excellent thermal conductivity for cooler operation and natural corrosion resistance in wet haymaking environments.

📚 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-RC61 is right for your operation:

📌 Selección de toma de fuerza (PTO) de 540 RPM frente a 1000 RPM
The EP-RC61 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-RC61 uses a grey 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-RC61 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-RC61 features 1 3/8 Z6, Taper spline 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 36.5 Kg, the EP-RC61 is designed for mid-size utility tractor attachments. 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. Use Nord-Lock washers or thread-locking compound on all mounting bolts to prevent vibration-induced loosening during operation.
  2. Haga funcionar la caja de cambios sin carga durante 5-10 minutos, luego apáguela y vuelva a comprobar el nivel de aceite; los sellos y cojinetes nuevos suelen absorber una pequeña cantidad de aceite inicial.
  3. Limpie a fondo la superficie de montaje del implemento, eliminando todo el óxido, los restos de juntas viejas, las escamas de pintura y los residuos que puedan impedir un contacto perfecto con la brida de la caja de engranajes.
  4. Coloque la caja de cambios sobre los espárragos de montaje o los orificios para los pernos, verificando que el eje de entrada esté orientado hacia la toma de fuerza del tractor y que el eje de salida esté alineado con el cubo de la cuchilla o el rotor.
  5. Asegúrese de que el eje de la toma de fuerza tenga una superposición de estrías de al menos 50% en todas las posiciones de funcionamiento. Una superposición insuficiente provoca un desgaste rápido de las estrías y una posible separación del eje.
  6. Anote la fecha de instalación, la lectura del contador de horas del tractor y el número de serie de la caja de cambios en su registro de mantenimiento para el seguimiento de la garantía y los intervalos de servicio.
  7. Si va a reemplazar una unidad existente, drene completamente el aceite viejo, retire los sujetadores de montaje y baje con cuidado la caja de engranajes vieja. Fotografie la posición y anote las arandelas de ajuste utilizadas.

❓ Preguntas frecuentes

❓ What happens if I accidentally run it dry?

Stop the PTO immediately. Even a few minutes without oil causes severe gear scoring and bearing damage, typically requiring a full internal rebuild. Always verify oil level before engaging the PTO.

❓ How should I store the gearbox off-season?

Run briefly to warm the oil, then top up to the full mark. Apply grease to exposed shaft surfaces and seal any open ports. Store in a dry, covered area. Before next season, verify oil level and rotate input by hand to check free movement.

❓ 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.
