🔄 Cross-Reference Compatibility for EP-RC51<\/h3>\n

The EP-RC51 is engineered as a direct replacement or upgrade for gearboxes fitted to equipment from leading manufacturers including:<\/p>\n

Bush Hog • Kioti • Vicon • Bomford • Valtra • Yanmar • Lovol • New Holland<\/p>\n

Penafian: Nama merek di atas hanya dirujuk untuk identifikasi kompatibilitas. Ever-power Australia Mower Gearbox Co.,Ltd. tidak berafiliasi dengan, didukung oleh, atau diotorisasi oleh produsen mana pun yang tercantum. Semua merek dagang milik pemiliknya masing-masing.<\/p>\n<\/div>\n

\ud83d\udcda Panduan Pemilihan Transmisi<\/h2>\n

The correct gearbox specification depends on your tractor, implement, and field conditions. Evaluate these factors for the EP-RC51:<\/p>\n

\n\ud83d\udccc Katalog Standar vs Spesifikasi Khusus<\/summary>\n
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.<\/div>\n<\/details>\n
\n📌 Output Shaft Type Compatibility<\/summary>\n
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 \u2014 spline, taper, keyway, and flange \u2014 to match virtually any existing installation.<\/div>\n<\/details>\n
\n📌 Weight and Mounting Considerations<\/summary>\n
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.<\/div>\n<\/details>\n
\n\ud83d\udccc Menyesuaikan Rasio Gigi dengan Kecepatan Ujung Pisau<\/summary>\n
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 \u00f7 ratio. Multiply by blade diameter to get tip speed.<\/div>\n<\/details>\n
\n\ud83d\udccc Penentuan Ukuran Daya yang Sesuai dengan Daya PTO Traktor<\/summary>\n
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.<\/div>\n<\/details>\n

\ud83d\udee0 Panduan Instalasi & Pengaturan<\/h2>\n
    \n
  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.<\/li>\n
  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.<\/li>\n
  3. Use Nord-Lock washers or thread-locking compound on all mounting bolts to prevent vibration-induced loosening during operation.<\/li>\n
  4. Run the gearbox at no load for 5-10 minutes, then shut down and re-check oil level \u2014 new seals and bearings often absorb a small amount of initial oil.<\/li>\n
  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.<\/li>\n
  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.<\/li>\n
  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.<\/li>\n<\/ol>\n

    \u2753 Pertanyaan yang Sering Diajukan<\/h2>\n
    \n
    \n❓ What PTO shaft should I pair with this gearbox?<\/summary>\n
    \n

    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.<\/p>\n<\/div>\n<\/details>\n

    \n❓ How does your pricing compare to genuine OEM parts?<\/summary>\n
    \n

    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.<\/p>\n<\/div>\n<\/details>\n

    \n\u2753 Spesifikasi oli transmisi apa yang dibutuhkan gearbox ini?<\/summary>\n
    \n

    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 \u00b0C, oli sintetis 75W-90 memastikan aliran yang tepat saat start dingin. Selalu periksa kaca pengintai atau tongkat pengukur oli sebelum setiap perpindahan gigi.<\/p>\n<\/div>\n<\/details>\n

    \n\u2753 Merek traktor mana yang kompatibel?<\/summary>\n
    \n

    Kotak roda gigi kami menggunakan koneksi PTO standar (1 3\/8\u2033 6-spline atau 1 3\/4\u2033 20-spline) yang kompatibel dengan hampir semua merek \u2014 John Deere, Kubota, Massey Ferguson, New Holland, Case IH, Kioti, Mahindra, dan banyak lagi.<\/p>\n<\/div>\n<\/details>\n

    \n\u2753 Seberapa berisik gearbox ini saat beroperasi?<\/summary>\n
    \n

    Desain bevel spiral kami menghasilkan 72-78 dB(A) pada jarak 1 meter di bawah beban nominal \u2014 jauh lebih senyap daripada alternatif bevel lurus (biasanya 82-88 dB). Operator merasakan pengurangan yang signifikan pada suara dengung roda gigi.<\/p>\n<\/div>\n<\/details>\n<\/div>\n
