⭐ 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:
🌾 Escenarios de aplicación típicos
🌾 Airfield perimeter and runway strip grass management
🚘 Sugar cane and crop stubble field mulching
🌱 Dairy farm laneway and yard surround maintenance
⛰ Conservation tillage and minimum-disturbance cultivation
🌳 Railway corridor vegetation control programs

🛠 Guía de instalación y configuración
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.

📍 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.
Javier R.
★★★★★
📍 Castilla, Spain
Oil change was simple thanks to the drain and fill locations being well-positioned. Small details like this show engineering thought.
Roberto C.
★★★★★
📍 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.
Hans B.
★★★★☆
📍 Bavaria, Germany
Bolt pattern matched my slasher perfectly. Quieter than the original gearbox it replaced and the oil stays clean much longer between changes.
George K.
★★★★☆
📍 Thessaly, Greece
Installed on our rotary cutter for sugarcane/crop field work. Oil seal quality is excellent — no leakage despite dusty and humid conditions.
