📚 Guía de selección de cajas de cambios

Choosing the right mower gearbox is critical for implement performance and longevity. Use the following criteria when evaluating the EP-140:

📌 Adaptación de la relación de engranajes a la velocidad de la punta de la cuchilla
For the EP-140 with ratio(s) 1:1.5 / 1:1.93, calculate your required blade tip speed: typically 4,500-5,500 m/min for standard rotary cutters, 3,000-4,000 m/min for heavy brush cutting, and 5,500-6,500 m/min for fine finish mowing. Output RPM = PTO RPM ÷ ratio. Multiply by blade diameter to get tip speed.
📌 Dimensionamiento de la potencia nominal en relación a la potencia de la toma de fuerza del tractor (HP)
The EP-140 is rated at 60 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-140 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-140 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-140 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.

🛠 Guía de instalación y configuración

  1. Primero, apriete todos los tornillos de montaje a mano y, a continuación, aplique el par de apriete especificado siguiendo un patrón en cruz (o estrella) para asegurar una sujeción uniforme. Par de apriete típico: 80-120 Nm, según el tamaño del tornillo.
  2. With the implement raised and blades clear of the ground, engage the PTO at low idle speed. Listen for any unusual noise and observe for vibration or oil leaks.
  3. Verify that the mower implement safety chain or restraint is properly connected to prevent the gearbox from contacting the ground if the three-point hitch fails.
  4. 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.
  5. 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.
  6. 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.
  7. Disconnect the tractor PTO shaft and safely support the mower implement on jack stands or blocks before beginning the gearbox installation procedure.

❓ Preguntas frecuentes

❓ Which tractor brands are compatible?

Our gearboxes use standard PTO connections (1 3/8″ 6-spline or 1 3/4″ 20-spline) compatible with virtually every brand — John Deere, Kubota, Massey Ferguson, New Holland, Case IH, Kioti, Mahindra, and more.

❓ How noisy is this gearbox during operation?

Our spiral bevel designs produce 72-78 dB(A) at 1 metre under rated load — significantly quieter than straight-bevel alternatives (typically 82-88 dB). Operators notice a meaningful reduction in gear whine.

❓ What is the difference between ratio options?

Ratio determines the speed/torque trade-off at the output. 1:1 maintains PTO speed (high blade RPM); 1:1.93 nearly halves output speed while doubling torque. Choose based on your target blade tip speed and vegetation density.

❓ What is the lead time for standard models?

In-stock standard models ship within 3-5 business days. For models requiring custom ratios or configurations, typical lead time is 4-6 weeks. Rush production is available for urgent requirements.

❓ How do I select the right gear ratio?

Match the ratio to your blade tip speed target. Lower ratios (e.g. 1:1) give higher blade RPM for finish mowing; higher ratios (e.g. 1:1.93 or above) trade speed for torque, ideal for thick brush. Calculate: output RPM = input RPM ÷ ratio.

⭐ Opiniones de clientes e informes de campo

★★★★★

📍 Nueva Gales del Sur, Australia

Good gearbox with a solid, hefty feel. Delivery to Australia was fast. Only needed a small spacer washer to fit our older mower model.

★★★★★

📍 Free State, South Africa

Handles our Mediterranean conditions well — wet winters and dry summers. This gearbox just keeps working without fuss.

★★★★★

📍 Otago, New Zealand

Bought for heavy paddock clearing work. Dust, heat, debris — it handles everything. The seals are particularly impressive in dirty conditions.

★★★★☆

📍 Normandy, France

Solid replacement unit. Took minimal effort to install. Once running, it is smooth and efficient. Good value for money.

★★★★☆

📍 Konya, Turkey

High quality comparable to European brands at roughly half the price. Gear tooth finish and bearing smoothness are both excellent.
