EP-9.259 Lawn Mower Gearbox

EP-9.259 Lawn Mower Gearbox

Weighing just 14 kg with a single 1.46:1 ratio, the EP-9.259 is our most compact rotary cutter gearbox. It is purpose-matched to sub-compact tractors under 30 HP where every kilogram matters — hobby smallholdings, estate lawns, and lightweight trailed slashers where space and weight are tightly constrained.

⭐ Características clave y ventajas de ingeniería

🌡

Custom-Angle Bevel Tooth Geometry

Non-standard bevel angles CNC-cut for unique shaft orientations, enabling implement designs that standard 90° gearboxes cannot accommodate.

🛠

Application-Tuned Non-Standard Ratio

Gear ratio calculated specifically for target output RPM and torque, matched to the precise blade speed requirements of the intended mowing/mulching implement.

🔬

Tip-Relief Quiet Gear Profile

Tooth profile modifications (tip relief + lead crowning) reduce gear-mesh noise by 6 dB versus standard straight bevel designs, improving operator comfort.

⚖

Abrasion-Resistant Cast Housing

Extra-thick grey iron walls with hardened mounting faces, resisting the abrasive wear caused by constant soil contact during deep tillage operations.

🚀

Bolt-On Precision Flange Mount

Machined flange with dowel pin locations for accurate, repeatable tiller frame alignment, eliminating vibration-inducing misalignment during extended tillage runs.

💪

Gear-Ground Tooth Flanks, Ra 0.5 μm

Post-heat-treatment gear grinding achieves consistent surface finish and AGMA Class 9 geometry, reducing running-in wear and extending time to first service.

📚 Guía de selección de cajas de cambios

A well-matched gearbox delivers years of trouble-free service. Follow this guide to confirm the EP-9.259 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-9.259 is rated at 30 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-9.259 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-9.259 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-9.259 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-9.259 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. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.

❓ Preguntas frecuentes

❓ 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.

❓ Do you manufacture custom ratios and shaft types?

Absolutely. We offer custom gear ratios, shaft profiles, and mounting configurations. Minimum order quantities apply for fully custom designs. Lead time is typically 4-6 weeks from order confirmation.

❓ What PTO shaft should I pair with this gearbox?

Use a standard agricultural PTO shaft rated for your tractor HP output with the matching spline profile. We strongly recommend shafts with shear bolt or friction clutch protection to prevent gearbox damage from sudden overloads.

⭐ Opiniones de clientes e informes de campo

📍 Queensland, Australia

Running it on a 25-35 HP tractor through rocky paddocks. Handles rocks and rough ground without complaint. Very impressed with the build.

★★★★★

📍 Tuscany, Italy

Purchased two units for our operation. Consistent quality between both units, which tells me their factory QC is solid. Will buy again.

★★★★★

📍 Punjab, India

Replaced a failed OEM unit on a 15-year-old mower. This new gearbox is actually smoother and quieter than the original ever was.

★★★★☆

📍 Free State, South Africa

Best aftermarket unit I have used in 20+ years of farming. Bolt holes aligned first try. Oil sight glass is a thoughtful touch.

★★★★☆

📍 Otago, New Zealand

Precision manufacturing is evident when you look at the gear teeth. Mesh noise is minimal. Very satisfied with this purchase.
