⭐ 主な特長とエンジニアリング上の利点

🚀

1 3/4″ Z20 Heavy-Duty Input Spline

Oversized 20-spline input rated for tractors to 160 HP, with hardened spline teeth and precision-honed bore for zero-backlash PTO engagement.

💪

Double-Row Output Bearings

Paired tapered roller bearings at the output position handle 45+ kN radial load, holding the shaft rigid under maximum cutting force from thick brush.

⚙

Five-Stage Hermetic Sealing

Labyrinth + double Viton + pressurized grease chamber + armored shield maintain hermetic integrity even during full submersion or high-pressure washdown.

⚗

8-Bolt Forged 4340 Output Hub

Nickel-chrome-moly steel output hub rated for 80 kg blade assemblies and sustained cutting torques above 2,000 Nm — our strongest output interface.

🔒

FKMバイトン高温シール

フッ素エラストマー製のシャフトシールは、-25℃から+200℃までの温度範囲に対応し、全天候型農業で遭遇する極端な季節的な温度変化においても漏れのない性能を維持します。

⚡

180mm未満のハブプロファイル

スリムな垂直形状により、ディスクの間隔を狭くすることができ、連続的で重なりのない刈り取りが可能になります。これは、密集したアルファルファや混合草地において、きれいな刈り跡を形成するために不可欠です。

📚 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-GS4RC:

📌重量と取り付けに関する考慮事項
At 19 Kg, the EP-GS4RC 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.
📌 ギア比とブレード先端速度のマッチング
For the EP-GS4RC with ratio(s) 1:1.46 / 1:1.93, 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-GS4RC is rated at 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.
📌 540 RPM vs 1000 RPM PTO Selection
The EP-GS4RC 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.
📌 Cast Iron Housing vs Aluminium Housing
The EP-GS4RC uses a grey 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. PTOシャフトは、すべての動作位置において、少なくとも50%のスプライン重なりを確保してください。重なりが不十分な場合、スプラインの摩耗が急速に進み、シャフトが分離する可能性があります。
  2. Record the installation date, tractor hour meter reading, and gearbox serial number in your maintenance log for warranty and service interval tracking.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.

❓よくある質問

❓ How do I determine the correct model for my mower?

You need four pieces of information: (1) tractor PTO HP, (2) PTO speed (540 or 1000 RPM), (3) current gearbox mounting dimensions, and (4) output shaft type. Send us these details and we will cross-reference the best match.

❓ Is synthetic gear oil recommended?

Synthetic PAO-based 75W-90 or 80W-140 GL-5 oil is excellent, especially in extreme temperatures. Synthetics offer better cold-flow, higher film strength, and longer drain intervals. Fully compatible with all our seal materials.

❓ 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.

⭐ お客様の声と現場レポート

★★★★★

📍 オーストラリア、タスマニア州

Our mechanic was impressed by the machining quality when he opened the box. Everything was precisely finished and well-protected for shipping.

★★★★★

📍 Saskatchewan, Canada

The split-line O-ring seal is a real bonus. Saves us time in the workshop and lets us spend more hours in the paddock. Great design.

★★★★★

📍 Hokkaido, Japan

Oil change was simple thanks to the drain and fill locations being well-positioned. Small details like this show engineering thought.

★★★★☆

📍 Castilla, Spain

We needed a gearbox fast after a mid-season failure. This arrived in 5 days, bolted on in an hour, and has been perfect since.

★★★★☆

📍 Mendoza, Argentina

Bolt pattern matched my slasher perfectly. Quieter than the original gearbox it replaced and the oil stays clean much longer between changes.
