EP20.100J.01WW Lawn Mower Gearbox

Despite weighing only 16 kg, the EP20.100J.01WW handles 100-120 HP through its 1:1 ratio and module 5.4 gear set — an industry-leading power-to-weight ratio. High-performance mower OEMs and racing-turf maintenance teams specify this model when minimum implement weight is as critical as maximum power throughput.

⭐ Características clave y ventajas de ingeniería

🔄

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.

🌡

Split-Line O-Ring Seal

Precision-machined housing split line with fluorocarbon O-ring eliminates the gasket creep and re-torque requirements of traditional paper or RTV gasket joints.

🛠

Low-Backlash Preloaded Assembly

Bearing preload and controlled gear mesh clearance hold total backlash below 0.08 mm, critical for reversing-load applications and precision-cut implements.

🔬

Redundant Lubrication Groove System

Machined oil distribution grooves in the housing bore supplement splash lubrication, providing a secondary oil path to bearings if sump level drops slightly below specification.

Reinforced Grey Cast Iron Housing

HT250-grade grey iron casing with 14 mm wall thickness, ribbed for vibration damping and thermal dissipation, resisting cracking from rock strikes at mowing speed.

📚 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 EP20.100J.01WW:

📌 Adaptación de la relación de engranajes a la velocidad de la punta de la cuchilla
For the EP20.100J.01WW with ratio(s) 1:1, 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 EP20.100J.01WW is rated at 100 / 120 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 EP20.100J.01WW 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 EP20.100J.01WW 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 EP20.100J.01WW 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. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.

❓ Preguntas frecuentes

❓ 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.

❓ What is the expected operational lifespan?

With proper maintenance, our gearboxes typically deliver 3,000 to 5,000 operating hours. Many units in the field have exceeded 6,000 hours. Lifespan depends on operating load, maintenance compliance, and field conditions.

❓ Is this suitable for mulching applications?

Yes. Our gearboxes are widely used on mulching mowers and brush cutters. For mulching, select a model rated 25-30% above your actual PTO horsepower to provide a safety margin against the intermittent shock loads typical of mulching.

❓ What quality inspections do you perform?

Every gearbox undergoes 100% dimensional inspection (CMM), gear tooth geometry verification (Gleason analyzer), hardness testing, oil-leak testing, and no-load run-in testing before shipment.

⭐ Opiniones de clientes e informes de campo

★★★★★

📍 Tasmania, Australia

The cooling fin design is a real bonus. Saves us time in the workshop and lets us spend more hours in the paddock. Great design.

★★★★★

📍 Castilla, Spain

Oil change was simple thanks to the drain and fill locations being well-positioned. Small details like this show engineering thought.

★★★★★

📍 Mendoza, Argentina

We needed a gearbox fast after a mid-season failure. This arrived in 5 days, bolted on in an hour, and has been perfect since.

★★★★☆

📍 Bavaria, Germany

Bolt pattern matched my slasher perfectly. Quieter than the original gearbox it replaced and the oil stays clean much longer between changes.

★★★★☆

📍 Thessaly, Greece

Installed on our rotary cutter for sugarcane/crop field work. Oil seal quality is excellent — no leakage despite dusty and humid conditions.
