\u2b50 Ciri-ciri Utama & Kelebihan Kejuruteraan<\/h2>\n
\n
\n

🔬<\/p>\n

Multi-Position Bolt Pattern<\/h4>\n

Versatile mounting interface with tapped holes at 0\u00b0, 90\u00b0, and 180\u00b0 orientations, fitting a wide range of implement frame geometries without adapter plates.<\/p>\n<\/div>\n

\n

⚖<\/p>\n

E-Coat + Powder Coat Finish<\/h4>\n

25 \u03bcm zinc-rich e-coat primer plus 80 \u03bcm polyester powder topcoat provides 1,000+ hours of ASTM B117 salt-spray corrosion resistance.<\/p>\n<\/div>\n

\n

🚀<\/p>\n

Heavy-Duty Triple-Lip Seals + Scraper<\/h4>\n

Three-lip shaft seals with external scraper rings prevent soil and moisture ingress even during tillage in waterlogged or heavily saturated ground.<\/p>\n<\/div>\n

\n

💪<\/p>\n

Dedicated Thrust Bearing Stage<\/h4>\n

Purpose-designed thrust bearings absorb the axial forces generated as tiller blades engage the soil, preventing shaft walk and premature seal extrusion.<\/p>\n<\/div>\n

\n

⚙<\/p>\n

Stainless Steel Breather Valve<\/h4>\n

Labyrinthed breather prevents pressure build-up during temperature swings while blocking water and dust ingress \u2014 a common failure point in cheaper gearboxes.<\/p>\n<\/div>\n

\n

⚗<\/p>\n

CNC-Bored Bearing Seats, IT6 Tolerance<\/h4>\n

All bearing bores finish-bored to ISO IT6 on CNC horizontal boring mills, ensuring perfect bearing fit and eliminating the fretting corrosion caused by loose seats.<\/p>\n<\/div>\n<\/div>\n

🔄 Cross-Reference Compatibility for EP-AG135<\/h3>\n

The EP-AG135 is engineered as a direct replacement or upgrade for gearboxes fitted to equipment from leading manufacturers including:<\/p>\n

Fella • Sonalika • Branson • Dongfeng • John Deere • AGCO • Rhino • LS Tractor<\/p>\n

\ud83d\udcda Panduan Pemilihan Kotak Gear<\/h2>\n

The EP-AG135 covers a specific performance envelope. Use these selection criteria to verify it aligns with your operational parameters:<\/p>\n

\n\ud83d\udccc Keserasian Jenis Aci Output<\/summary>\n
The EP-AG135 features 1 3\/8 Z6, Cone base aequilate spline shaft 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\ud83d\udccc Pertimbangan Berat dan Pemasangan<\/summary>\n
At 16.5 Kg, the EP-AG135 is designed for mid-size utility tractor attachments. 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📌 Matching Gear Ratio to Blade Tip Speed<\/summary>\n
For the EP-AG135 with ratio(s) 1:1, 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📌 Sizing Power Rating to Tractor PTO HP<\/summary>\n
The EP-AG135 is rated at 50 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
\n\ud83d\udccc Pilihan PTO 540 RPM vs 1000 RPM<\/summary>\n
The EP-AG135 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 \u2014 the doubled speed will destroy bearings and gears within minutes.<\/div>\n<\/details>\n

\ud83d\udee0 Panduan Pemasangan & Persediaan<\/h2>\n
    \n
  1. 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.<\/li>\n
  2. 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.<\/li>\n
  3. 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.<\/li>\n
  4. 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.<\/li>\n
  5. Sapukan manik pengedap silikon RTV yang nipis dan sekata pada permukaan bebibir pelekap jika gasket pra-potong tidak disertakan dengan kotak gear baharu.<\/li>\n
  6. Sambungkan aci pemacu PTO ke spline input kotak gear. Tolak aci sepenuhnya dan sahkan ia boleh bergerak bebas melalui julat lengkap pergerakan hitch tiga titik.<\/li>\n
  7. Selepas 10 jam pertama operasi, tork semula semua bolt pelekap mengikut spesifikasi dan sahkan paras minyak. Lakukan saliran minyak pertama dan isi semula pada 50 jam.<\/li>\n<\/ol>\n

    \u2753 Soalan Lazim<\/h2>\n
    \n
    \n\u2753 Adakah anda menyediakan lukisan dimensi?<\/summary>\n
    \n

    Lukisan teknikal penuh \u2014 lubang pelekap, spesifikasi aci, dimensi sampul surat \u2014 tersedia untuk setiap model. Muat turun dari halaman produk kami atau minta dari jabatan teknikal kami tanpa sebarang caj.<\/p>\n<\/div>\n<\/details>\n

    \n❓ Do you offer technical support after purchase?<\/summary>\n
    \n

    Yes. Our technical team provides installation guidance, troubleshooting support, and maintenance advice via phone, email, and video call. We also offer on-site training for fleet operators and dealer technicians.<\/p>\n<\/div>\n<\/details>\n

    \n❓ Is this gearbox safe to run at 1000 RPM PTO speed?<\/summary>\n
    \n

    This unit is rated for 540 RPM input. Operating at 1000 RPM without the correct gear set will over-speed bearings and gears, causing rapid failure. Contact our team if you need a 1000 RPM-rated configuration.<\/p>\n<\/div>\n<\/details>\n

    \n❓ Can I mount this gearbox at non-standard angles?<\/summary>\n
    \n

    Most models are designed for vertical or horizontal output as specified. Mounting at unusual angles can affect oil distribution. Contact our engineering team to confirm suitability before installing in a non-standard orientation.<\/p>\n<\/div>\n<\/details>\n

    \n❓ How do I identify when my gearbox needs repair?<\/summary>\n
    \n

    Warning signs: unusual grinding or whining noise, increased vibration, oil leakage, metallic particles on the magnetic drain plug, elevated operating temperature, or detectable play in the output shaft.<\/p>\n<\/div>\n<\/details>\n<\/div>\n
