⭐ Características clave y ventajas de ingeniería

🔄

20CrMnTi Forged Gear Blanks

All gear blanks are closed-die forged (not cast) to align grain flow with tooth roots, increasing bending fatigue strength by 30% over alternative casting methods.

🔨

97%+ Mechanical Efficiency Rating

Super-finished gear flanks (Ra ≤ 0.6 μm) and optimized tooth contact deliver over 97% efficiency, reducing fuel consumption and allowing cooler continuous operation.

🌡

Premium Tapered Roller Bearings

All positions fitted with Japanese-standard tapered roller bearings rated for 5,000+ hours L10 life, handling combined radial and thrust loads simultaneously.

🛠

GGG-50 Spheroidal Iron Casing

EN-GJS-500-7 housing tested to 25 bar hydrostatic pressure, providing extreme fatigue strength for applications exceeding 100 HP continuous input power.

🔬

1 3/4″ Z20 Heavy-Duty Input Spline

Oversized 20-spline input rated for tractors to 160 HP, with hardened spline teeth and precision-honed bore for zero-backlash PTO engagement.

⚖

Double-Row Output Bearings

Paired tapered roller bearings at the output position handle 45+ kN radial load, holding the shaft rigid under maximum cutting force from thick brush.

📚 Guía de selección de cajas de cambios

A well-matched gearbox delivers years of trouble-free service. Follow this guide to confirm the EP-LF211 is the optimal choice for your needs:

📌 Dimensionamiento de la potencia nominal en relación a la potencia de la toma de fuerza del tractor (HP)
The EP-LF211 is rated at 20 HP. Always select a gearbox rated at or above your tractor’s maximum PTO horsepower. For shock-load applications (mulching, brush clearing), add a 25-30% safety margin: a 60 HP tractor should use a 75+ HP rated gearbox.
📌 Selección de toma de fuerza (PTO) de 540 RPM frente a 1000 RPM
The EP-LF211 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-LF211 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-LF211 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-LF211 features 1 3/8 Z6, Optic axis 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.

🛠 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

❓ ¿Es seguro hacer funcionar esta caja de cambios a una velocidad de toma de fuerza de 1000 RPM?

Esta unidad está diseñada para funcionar a 540 RPM. Si se opera a 1000 RPM sin el engranaje adecuado, los cojinetes y engranajes se sobrecargarán, lo que provocará una falla rápida. Si necesita una configuración para 1000 RPM, comuníquese con nuestro equipo.

❓ ¿Puedo montar esta caja de cambios en ángulos no estándar?

La mayoría de los modelos están diseñados para salida vertical u horizontal, según se especifique. El montaje en ángulos inusuales puede afectar la distribución del aceite. Póngase en contacto con nuestro equipo de ingeniería para confirmar la idoneidad antes de instalarlo en una orientación no estándar.

❓ How do I identify when my gearbox needs repair?

Warning signs: unusual grinding or whining noise, increased vibration, oil leakage, metallic particles on the magnetic drain plug, elevated operating temperature, or detectable play in the output shaft.

❓ Can I visit your manufacturing facility?

We welcome factory visits and audits from prospective partners. Our production facility is equipped for full tours, and we can arrange local transport from the nearest airport. Contact us to schedule a convenient date.

❓ What is the recommended oil change schedule?

Drain and replace oil after the first 50 hours of break-in. After that, change oil every 200-300 hours or at least once per season. Always drain warm oil for complete evacuation and inspect the magnetic drain plug for metallic debris.

⭐ Opiniones de clientes e informes de campo

★★★★★

📍 Tasmania, Australia

Fast shipping, professional packaging, and the gearbox itself is built like a tank. Highly recommended for serious agricultural work.

★★★★★

📍 São Paulo, Brazil

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

★★★★★

📍 Skåne, Suecia

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

★★★★☆

📍 Alentejo, Portugal

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

★★★★☆

📍 Canterbury, Nueva Zelanda

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