⭐ Belangrijkste kenmerken en technische voordelen

Five-Stage Hermetic Sealing

Labyrinth + double Viton + pressurized grease chamber + armored shield maintain hermetic integrity even during full submersion or high-pressure washdown.

🔒

8-Bolt Forged 4340 Output Hub

Nickel-chrome-moly steel output hub rated for 80 kg blade assemblies and sustained cutting torques above 2,000 Nm — our strongest output interface.

FKM Viton High-Temperature Seals

Fluoroelastomer shaft seals rated from -25 °C to +200 °C, maintaining leak-free performance through the extreme seasonal temperature swings encountered in all-weather farming.

🔄

Sub-180 mm Hub Profile

Slim vertical envelope allows close disc spacing for continuous, overlap-free cutting — critical for clean swath formation in thick alfalfa and mixed-grass stands.

🔨

Self-Contained Bearing Cartridges

Pre-loaded, pre-lubricated cartridge bearings drop in for rapid field replacement, slashing unplanned downtime from bearing failures by up to 70%.

🌡

Synthetic PAO Fill, -40 to +150 °C

Factory-filled with polyalphaolefin gear oil maintaining viscosity stability from arctic cold starts to sustained high-temperature tropical operation without degradation.

📚 Gids voor het kiezen van een versnellingsbak

The EP-01-661 covers a specific performance envelope. Use these selection criteria to verify it aligns with your operational parameters:

📌 Output Shaft Type Compatibility
The EP-01-661 features 1 3/4 Z20 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.
📌 Weight and Mounting Considerations
At 57.5 Kg, the EP-01-661 is designed for large-frame tractor implements and heavy-duty mowers. Confirm your implement frame and three-point hitch can support this weight plus the weight of the blade assembly. Mounting bolt pattern and orientation should match your existing layout.
📌 Afstemming van de overbrengingsverhouding op de snelheid van de bladpunt
For the EP-01-661 with ratio(s) 1:1.3, 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.
📌 Vermogensclassificatie afstemmen op aftakasvermogen (PTO) van de tractor
The EP-01-661 is rated at 80 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-01-661 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.

🛠 Installatie- en configuratiehandleiding

  1. Run the gearbox at no load for 5-10 minutes, then shut down and re-check oil level — new seals and bearings often absorb a small amount of initial oil.
  2. Clean the implement mounting surface thoroughly, removing all rust, old gasket material, paint flakes, and debris that could prevent flush contact with the gearbox flange.
  3. Position the gearbox onto the mounting studs or bolt holes, verifying the input shaft faces the tractor PTO and the output shaft aligns with the blade hub or rotor.
  4. Ensure the PTO shaft has at least 50% spline overlap in all operating positions. Inadequate overlap causes rapid spline wear and potential shaft separation.
  5. Record the installation date, tractor hour meter reading, and gearbox serial number in your maintenance log for warranty and service interval tracking.
  6. If replacing an existing unit, drain the old oil completely, remove mounting fasteners, and carefully lower the old gearbox. Photograph the orientation and note any shim washers used.
  7. Insert all mounting bolts finger-tight first, then torque to specification in a cross (star) pattern to ensure even clamping. Typical torque: 80-120 Nm depending on bolt size.

❓ Veelgestelde vragen

❓ Can I buy individual spare parts?

Yes. We stock complete spare part inventories — gear sets, bearings, seals, shafts, and hardware — for every model we produce. Parts ship worldwide and most in-stock items dispatch within 24 hours of order.

❓ Do you provide dimensional drawings?

Full technical drawings — mounting holes, shaft specs, envelope dimensions — are available for every model. Download from our product pages or request from our technical department at no charge.

❓ Do you offer technical support after purchase?

Yes. Our technical team provides installation guidance, troubleshooting support, and maintenance advice via phone, email, and video call. We also offer on-site training for fleet operators and dealer technicians.

❓ 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.
