⭐ Fitur Utama & Keunggulan Teknik

🚀

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 Viton High-Temperature Seals

Fluoroelastomer shaft seals rated from -25 °C to +200 °C, maintaining leak-free performance through the extreme seasonal temperature swings encountered in all-weather farming.

⚡

Sub-180 mm Hub Profile

Slim vertical envelope allows close disc spacing for continuous, overlap-free cutting — critical for clean swath formation in thick alfalfa and mixed-grass stands.

📚 Panduan Pemilihan Transmisi

Selecting a gearbox that matches your exact requirements avoids premature wear and costly downtime. Consider these points for the EP-GS4RC:

📌 Weight and Mounting Considerations
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.
📌 Menyesuaikan Rasio Gigi dengan Kecepatan Ujung Pisau
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.
📌 Penentuan Ukuran Daya yang Sesuai dengan Daya PTO Traktor
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.
📌 Pilihan PTO 540 RPM vs 1000 RPM
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.
📌 Casing Besi Cor vs Casing Aluminium
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.

🛠 Panduan Instalasi & Pengaturan

  1. Pastikan poros PTO memiliki tumpang tindih spline minimal 50% di semua posisi pengoperasian. Tumpang tindih yang tidak memadai menyebabkan keausan spline yang cepat dan potensi pemisahan poros.
  2. Catat tanggal pemasangan, pembacaan meter jam traktor, dan nomor seri gearbox dalam buku catatan perawatan Anda untuk keperluan garansi dan pelacakan interval servis.
  3. Jika mengganti unit yang sudah ada, tiriskan oli lama sepenuhnya, lepaskan pengencang pemasangan, dan turunkan gearbox lama dengan hati-hati. Foto orientasinya dan catat ring pengganjal yang digunakan.
  4. Pasang semua baut pemasangan dengan cara dikencangkan secukupnya terlebih dahulu, kemudian kencangkan sesuai spesifikasi dengan pola silang (bintang) untuk memastikan pengencangan yang merata. Torsi tipikal: 80-120 Nm tergantung pada ukuran baut.
  5. Dengan alat terangkat dan mata pisau tidak menyentuh tanah, aktifkan PTO pada kecepatan idle rendah. Dengarkan apakah ada suara yang tidak biasa dan amati apakah ada getaran atau kebocoran oli.
  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.

❓ Pertanyaan yang Sering Diajukan

❓ 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.

⭐ Ulasan Pelanggan & Laporan Lapangan

★★★★★

📍 Tasmania, Australia

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.
