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.

📚 Gids voor het kiezen van een versnellingsbak

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:

📌 Vermogensclassificatie afstemmen op aftakasvermogen (PTO) van de tractor
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.
📌 Keuze tussen 540 tpm en 1000 tpm aftakas
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.
📌 Gietijzeren behuizing versus aluminium behuizing
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.
📌 Standaardcatalogus versus specificaties op maat
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.
📌 Output Shaft Type Compatibility
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.

🛠 Installatie- en configuratiehandleiding

  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. Na de eerste 10 bedrijfsuren alle bevestigingsbouten opnieuw vastdraaien volgens de specificaties en het oliepeil controleren. De eerste olieverversing uitvoeren na 50 bedrijfsuren.
  4. Koppel de aftakas van de tractor los en ondersteun het maaiwerktuig veilig met krikken of blokken voordat u begint met de installatie van de versnellingsbak.
  5. Voor units die meer dan 25 kg wegen, gebruik een kettingtakel, motortakel of een hijsinstallatie met twee personen om de versnellingsbak te positioneren. Probeer nooit zware versnellingsbakken in je eentje te tillen.
  6. Vul de versnellingsbak bij met de aanbevolen versnellingsbakolie (SAE 80W-90 of 85W-140 EP) tot het niveau dat is aangegeven op het kijkglas of de peilstok. Niet te veel bijvullen.
  7. Voordat u op vol vermogen gaat werken, doorloop een geleidelijke inloopperiode: 30 minuten op half gas, vervolgens 30 minuten op driekwart gas, voordat u het volledige aftakastoerental inschakelt.

❓ Veelgestelde vragen

❓ Is this gearbox safe to run at 1000 RPM PTO speed?

This unit is rated for 540 RPM input. Operating at 1000 RPM without the correct gear set will over-speed bearings and gears, causing rapid failure. Contact our team if you need a 1000 RPM-rated configuration.

❓ Can I mount this gearbox at non-standard angles?

Most models are designed for vertical or horizontal output as specified. Mounting at unusual angles can affect oil distribution. Contact our engineering team to confirm suitability before installing in a non-standard orientation.

❓ 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.

⭐ Klantenrecensies en praktijkverslagen

★★★★★

📍 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, Sweden

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, New Zealand

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