⭐ Belangrijkste kenmerken en technische voordelen

⚖

Quadruple-Barrier Environmental Sealing

Labyrinth + twin Viton FKM seals + armored debris shield achieve IP67, protecting against total submersion and high-pressure cleaning equipment.

🚀

Forced-Splash Oil Distribution

Gear-driven splash channels route lubricant to every bearing and mesh zone even on hillside slopes up to 35°, preventing dry-running at extreme operating angles.

💪

AISI 9310 Aircraft-Grade Gears

Vacuum-carburized, cryogenically treated gears reaching HRC 62-65 surface with a ductile core — the same metallurgy used in helicopter transmission gears.

⚙

99% Peak Efficiency, AGMA Class 12

Super-finished teeth ground to ≤ 0.2 μm Ra with class-leading accuracy, transmitting power with virtually zero parasitic friction at rated speed and load.

⚗

Hypoid Gear Precision Set

High-precision hypoid gears from 20MnCr5 steel, carburized and ground to AGMA Class 9, for smooth and quiet power transfer inside disc mower hubs.

🔒

Concentric Blade-Mount Hub

Precision-machined pilot diameter and balanced bolt circle ensure vibration-free disc rotation, maintaining uniform cutting height across the full mower bar width.

📚 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-01-790:

📌 Standaardcatalogus versus specificaties op maat
The EP-01-790 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-01-790 features 1 3/8 Z6 / Keyway 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 22 Kg, the EP-01-790 is designed for compact and sub-compact tractor implements. 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-01-790 with ratio(s) 1:1.92 / 1:2.5, 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-01-790 is rated at 40 / 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.

🛠 Installatie- en configuratiehandleiding

  1. 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.
  2. Na de eerste 10 bedrijfsuren alle bevestigingsbouten opnieuw vastdraaien volgens de specificaties en het oliepeil controleren. De eerste olieverversing uitvoeren na 50 bedrijfsuren.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. Controleer met een liniaal of de montageplaat van het werktuig vlak is. Eventuele krommingen van meer dan 0,5 mm moeten worden gecorrigeerd voordat de nieuwe versnellingsbak wordt gemonteerd.

❓ Veelgestelde vragen

❓ 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.

❓ 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.
