⭐ Belangrijkste kenmerken en technische voordelen

🌡

Interference-Fit Bearing Installation

All bearings installed with controlled interference fit using induction heating, preventing the spinning-in-bore failures common in slip-fit assemblies.

🛠

Hardened Shift Fork Mechanism

For multi-ratio models: induction-hardened shift fork and detent system provides positive gear engagement with tactile confirmation, preventing half-engagement damage.

🔬

Hot-Dip Galvanized Mounting Hardware

Grade 10.9 mounting bolts hot-dip galvanized to AS/NZS 4680, resisting corrosion in coastal and high-humidity farming regions like northern Queensland and Waikato.

⚖

Field-Rebuildable Modular Design

All internal components — gears, bearings, seals, shafts — are individually replaceable in the field with standard hand tools, eliminating the need to send units away for factory rebuild.

🚀

Dual-Lip NBR Oil Seals

Twin-lip nitrile seals with integrated dust excluder on every shaft exit, rated to IP65, preventing moisture and crop debris from entering the gear chamber.

💪

Optimized Lightweight Geometry

Finite-element-optimized casing walls remove unnecessary material while maintaining full load capacity, reducing installed weight by 15% versus previous-generation housings.

📚 Gids voor het kiezen van een versnellingsbak

The correct gearbox specification depends on your tractor, implement, and field conditions. Evaluate these factors for the EP01-672:

📌 Standaardcatalogus versus specificaties op maat
The EP01-672 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 EP01-672 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.
📌 Weight and Mounting Considerations
At 18.5 Kg, the EP01-672 is designed for mid-size utility tractor attachments. 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 EP01-672 with ratio(s) 1.92:1 / 1.47:1, 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 EP01-672 is rated at 50 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. 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.
  2. 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.
  3. 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.
  4. 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.
  5. Na de eerste 10 bedrijfsuren alle bevestigingsbouten opnieuw vastdraaien volgens de specificaties en het oliepeil controleren. De eerste olieverversing uitvoeren na 50 bedrijfsuren.
  6. 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.
  7. 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.

❓ Veelgestelde vragen

❓ 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.

❓ Wat is de levertijd voor standaardmodellen?

Standaardmodellen die op voorraad zijn, worden binnen 3-5 werkdagen verzonden. Voor modellen met aangepaste verhoudingen of configuraties bedraagt ​​de gemiddelde levertijd 4-6 weken. Spoedproductie is mogelijk voor dringende bestellingen.
