⭐ Belangrijkste kenmerken en technische voordelen

💪

Heavy-Duty Triple-Lip Seals + Scraper

Three-lip shaft seals with external scraper rings prevent soil and moisture ingress even during tillage in waterlogged or heavily saturated ground.

⚙

Dedicated Thrust Bearing Stage

Purpose-designed thrust bearings absorb the axial forces generated as tiller blades engage the soil, preventing shaft walk and premature seal extrusion.

⚗

Stainless Steel Breather Valve

Labyrinthed breather prevents pressure build-up during temperature swings while blocking water and dust ingress — a common failure point in cheaper gearboxes.

🔒

CNC-Bored Bearing Seats, IT6 Tolerance

All bearing bores finish-bored to ISO IT6 on CNC horizontal boring mills, ensuring perfect bearing fit and eliminating the fretting corrosion caused by loose seats.

⚡

Laser-Etched Traceability Code

Every housing is laser-marked with a unique serial number linking to full material, heat-treatment, and inspection records for complete supply-chain traceability.

🔄

Balanced Gear Set Assembly

Complete gear sets are dynamically balanced as a matched pair to ISO G6.3, reducing transmitted vibration to the mower frame and extending component fatigue life.

📚 Gids voor het kiezen van een versnellingsbak

The correct gearbox specification depends on your tractor, implement, and field conditions. Evaluate these factors for the EP-9.279:

📌 Standaardcatalogus versus specificaties op maat
The EP-9.279 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-9.279 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 38 Kg, the EP-9.279 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-9.279 with ratio(s) 1:1.5 / 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.
📌 Vermogensclassificatie afstemmen op aftakasvermogen (PTO) van de tractor
The EP-9.279 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.

🛠 Installatie- en configuratiehandleiding

  1. 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.
  2. Ensure the PTO shaft has at least 50% spline overlap in all operating positions. Inadequate overlap causes rapid spline wear and potential shaft separation.
  3. Record the installation date, tractor hour meter reading, and gearbox serial number in your maintenance log for warranty and service interval tracking.
  4. 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.
  5. 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.
  6. 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.
  7. 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.

❓ Veelgestelde vragen

❓ How does your pricing compare to genuine OEM parts?

Our gearboxes use equivalent or superior materials at typically 30-50% less than OEM pricing. Independent testing confirms comparable or better performance and service life. The savings are significant for fleet operators.

❓ What gear oil specification does this gearbox require?

Use SAE 80W-90 or SAE 85W-140 GL-5 extreme-pressure gear oil under normal conditions. For sub-zero climates below -20 °C, a synthetic 75W-90 ensures proper cold-start flow. Always check the sight glass or dipstick before each shift.

❓ Which tractor brands are compatible?

Our gearboxes use standard PTO connections (1 3/8″ 6-spline or 1 3/4″ 20-spline) compatible with virtually every brand — John Deere, Kubota, Massey Ferguson, New Holland, Case IH, Kioti, Mahindra, and more.

❓ Hoeveel lawaai maakt deze versnellingsbak tijdens gebruik?

Onze spiraalvormige tandwieloverbrengingen produceren 72-78 dB(A) op 1 meter afstand onder nominale belasting – aanzienlijk stiller dan alternatieven met rechte tandwieloverbrenging (doorgaans 82-88 dB). Gebruikers merken een merkbare vermindering van het geluid van de tandwielen.

❓ Wat is het verschil tussen de verschillende verhoudingsopties?

De verhouding bepaalt de balans tussen snelheid en koppel aan de uitgang. Een verhouding van 1:1 zorgt voor een constant aftakastoerental (hoog toerental van de messen); een verhouding van 1:1,93 halveert bijna de uitgangssnelheid en verdubbelt het koppel. Kies de verhouding op basis van de gewenste messensnelheid en de vegetatiedichtheid.

⭐ Klantenrecensies en praktijkverslagen

★★★★★

📍 South Australia, Australia

Running in extreme cold (-25 °C) winters and hot summers. Synthetic oil in this gearbox handles both extremes without issue.

★★★★★

📍 Faisalabad, Pakistan

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

★★★★★

📍 Poltava, Oekraïne

Third year of heavy use on our paddock clearing. Still going strong with just regular oil changes. The best aftermarket gearbox I have found.

★★★★☆

📍 Córdoba, Argentinië

Good gearbox with a solid, hefty feel. Delivery to Argentina was fast. Only needed a small spacer washer to fit our older mower model.

★★★★☆

📍 Bordeaux, France

Handles our tropical conditions well — humidity and monsoon rain. This gearbox just keeps working without fuss.
