⭐ 主な特長とエンジニアリング上の利点

⚙

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.

📚 ギアボックス選定ガイド

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

📌重量と取り付けに関する考慮事項
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.
📌 ギア比とブレード先端速度のマッチング
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.
📌トラクターPTO馬力に対する出力定格の選定
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.
📌 540 RPM 対 1000 RPM PTO の選択
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.
📌鋳鉄製ハウジング vs アルミニウム製ハウジング
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.

🛠 インストールとセットアップガイド

  1. 重量が25kgを超えるユニットの場合は、チェーンホイスト、エンジンクレーン、または2人作業用のリフトを使用してギアボックスを設置してください。重いギアボックスを一人で持ち上げようとしないでください。
  2. ギアボックスには、サイトグラスまたはディップスティックに示されたレベルまで、推奨ギアオイル（SAE 80W-90または85W-140 EP）を注入してください。入れすぎないでください。
  3. 全負荷運転を行う前に、段階的な慣らし運転を行ってください。まず、スロットルを半分開けて30分間運転し、次にスロットルを4分の3開けて30分間運転してから、PTOを全開速度で運転してください。
  4. 定規を使って、作業機の取り付け面が平坦かどうかを点検してください。0.5mmを超える歪みがある場合は、新しいギアボックスを取り付ける前に修正する必要があります。
  5. 運転中の振動による緩みを防ぐため、すべての取り付けボルトにNord-Lockワッシャーまたはねじロック剤を使用してください。
  6. ギアボックスを無負荷状態で5～10分間運転した後、停止させてオイルレベルを再確認してください。新しいシールやベアリングは、初期段階で少量のオイルを吸収することがよくあります。
  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.

❓よくある質問

❓ 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.

⭐ お客様の声と現場レポート

★★★★★

📍 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

しっかりとした交換部品です。取り付けは最小限の手間で済みました。稼働後はスムーズで効率的です。価格に見合った価値があります。
