⭐ Fitur Utama & Keunggulan Teknik

🔄

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.

🌡

Self-Contained Bearing Cartridges

Pre-loaded, pre-lubricated cartridge bearings drop in for rapid field replacement, slashing unplanned downtime from bearing failures by up to 70%.

🛠

Synthetic PAO Fill, -40 to +150 °C

Factory-filled with polyalphaolefin gear oil maintaining viscosity stability from arctic cold starts to sustained high-temperature tropical operation without degradation.

🔬

Through-Hardened Spur Gear Train

HRC 56-60 alloy steel spur gears designed for the high-impact reversing loads encountered during aggressive rotary tiller soil engagement.

⚖

3× Peak Torque Output Capacity

Oversized output shaft rated for transient torques three times nominal, absorbing the repeated shock loads when tiller blades strike buried rocks and roots.

📚 Panduan Pemilihan Transmisi

The correct gearbox specification depends on your tractor, implement, and field conditions. Evaluate these factors for the EP-RC51:

📌 Katalog Standar vs Spesifikasi Khusus
The EP-RC51 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-RC51 features Spline / Taper spline 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 29 Kg, the EP-RC51 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-RC51 with ratio(s) 1:1.47 / 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-RC51 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.

🛠 Panduan Instalasi & Pengaturan

  1. Before operating at full load, run through a graduated break-in sequence: 30 minutes at half-throttle, then 30 minutes at three-quarter throttle, before engaging full PTO speed.
  2. Inspect the implement mounting pad for flatness using a straightedge. Any warping exceeding 0.5 mm should be corrected before the new gearbox is installed.
  3. Use Nord-Lock washers or thread-locking compound on all mounting bolts to prevent vibration-induced loosening during operation.
  4. 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.
  5. Bersihkan permukaan tempat pemasangan alat secara menyeluruh, hilangkan semua karat, sisa material paking lama, serpihan cat, dan kotoran yang dapat menghalangi kontak yang rapat dengan flensa gearbox.
  6. Posisikan kotak roda gigi pada baut atau lubang pemasangan, pastikan poros input menghadap PTO traktor dan poros output sejajar dengan hub pisau atau rotor.
  7. 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.

❓ Pertanyaan yang Sering Diajukan

❓ 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.

❓ Spesifikasi oli transmisi apa yang dibutuhkan gearbox ini?

Gunakan oli gir tekanan ekstrem SAE 80W-90 atau SAE 85W-140 GL-5 dalam kondisi normal. Untuk iklim di bawah nol derajat Celcius, di bawah -20 °C, oli sintetis 75W-90 memastikan aliran yang tepat saat start dingin. Selalu periksa kaca pengintai atau tongkat pengukur oli sebelum setiap perpindahan gigi.

❓ Merek traktor mana yang kompatibel?

Kotak roda gigi kami menggunakan koneksi PTO standar (1 3/8″ 6-spline atau 1 3/4″ 20-spline) yang kompatibel dengan hampir semua merek — John Deere, Kubota, Massey Ferguson, New Holland, Case IH, Kioti, Mahindra, dan banyak lagi.

❓ Seberapa berisik gearbox ini saat beroperasi?

Desain bevel spiral kami menghasilkan 72-78 dB(A) pada jarak 1 meter di bawah beban nominal — jauh lebih senyap daripada alternatif bevel lurus (biasanya 82-88 dB). Operator merasakan pengurangan yang signifikan pada suara dengung roda gigi.
