⭐ Belangrijkste kenmerken en technische voordelen

⚙

Bolt-On Precision Flange Mount

Machined flange with dowel pin locations for accurate, repeatable tiller frame alignment, eliminating vibration-inducing misalignment during extended tillage runs.

⚗

Gear-Ground Tooth Flanks, Ra 0.5 μm

Post-heat-treatment gear grinding achieves consistent surface finish and AGMA Class 9 geometry, reducing running-in wear and extending time to first service.

🔒

Hardened Dowel-Pin Alignment

Two precision ground dowel pins locate the housing halves within 0.02 mm, guaranteeing gear centre distance accuracy and eliminating assembly-induced backlash.

⚡

Zinc Flake Anti-Corrosion Fasteners

All external bolts finished with zinc-flake coating (Delta-Protekt) rated for 720 hours of salt spray, preventing seized fasteners during later disassembly.

🔄

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.

📚 Gids voor het kiezen van een versnellingsbak

Selecting a gearbox that matches your exact requirements avoids premature wear and costly downtime. Consider these points for the EP-MDH-40:

📌 Weight and Mounting Considerations
At 15 Kg (approx.), the EP-MDH-40 is designed for disc mower cutter bars. 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-MDH-40 with ratio(s) N/A (Hub Drive), 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-MDH-40 is rated at 40 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-MDH-40 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-MDH-40 uses a aluminium alloy or 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.

🛠 Installatie- en configuratiehandleiding

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. Gebruik Nord-Lock-ringen of schroefdraadborgmiddel op alle bevestigingsbouten om losraken door trillingen tijdens gebruik te voorkomen.
  6. 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.
  7. 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.

❓ Veelgestelde vragen

❓ What shipping methods are available?

Sea freight (20-35 days), air freight (5-10 days), and express courier (3-5 days) worldwide. Sea freight is most economical for bulk orders. All shipments include protective packaging, documentation, and full tracking.

❓ Can this unit directly replace my OEM gearbox?

Yes. Our mounting patterns, shaft diameters, and spline profiles match industry-standard OEM dimensions. We supply detailed technical drawings for cross-referencing. If your existing unit differs slightly, our engineering team can advise on adapters.

❓ What happens if I accidentally run it dry?

Stop the PTO immediately. Even a few minutes without oil causes severe gear scoring and bearing damage, typically requiring a full internal rebuild. Always verify oil level before engaging the PTO.

❓ How should I store the gearbox off-season?

Run briefly to warm the oil, then top up to the full mark. Apply grease to exposed shaft surfaces and seal any open ports. Store in a dry, covered area. Before next season, verify oil level and rotate input by hand to check free movement.

❓ Can I replace just the gear set?

Yes. Replacement gear sets are available for all models and are cost-effective when the housing, bearings, and shafts remain in good condition. We recommend replacing bearings and seals simultaneously for best results.

⭐ Klantenrecensies en praktijkverslagen

★★★★★

📍 Queensland, Australia

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

★★★★★

📍 Kent, England

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

★★★★★

📍 São Paulo, Brazil

Handles our Mediterranean conditions well — wet winters and dry summers. This gearbox just keeps working without fuss.

★★★★☆

📍 Skåne, Sweden

Bought for heavy vineyard maintenance work. Dust, heat, debris — it handles everything. The seals are particularly impressive in dirty conditions.

★★★★☆

📍 Alentejo, Portugal

Solid replacement unit. Took minimal effort to install. Once running, it is smooth and efficient. Good value for money.
