⭐ Ciri-ciri Utama & Kelebihan Kejuruteraan

🌡

Interference-Fit Bearing Installation

All bearings installed with controlled interference fit using induction heating, preventing the spinning-in-bore failures common in slip-fit assemblies.

🛠

Hardened Shift Fork Mechanism

For multi-ratio models: induction-hardened shift fork and detent system provides positive gear engagement with tactile confirmation, preventing half-engagement damage.

🔬

Hot-Dip Galvanized Mounting Hardware

Grade 10.9 mounting bolts hot-dip galvanized to AS/NZS 4680, resisting corrosion in coastal and high-humidity farming regions like northern Queensland and Waikato.

⚖

Field-Rebuildable Modular Design

All internal components — gears, bearings, seals, shafts — are individually replaceable in the field with standard hand tools, eliminating the need to send units away for factory rebuild.

🚀

Dual-Lip NBR Oil Seals

Twin-lip nitrile seals with integrated dust excluder on every shaft exit, rated to IP65, preventing moisture and crop debris from entering the gear chamber.

💪

Optimized Lightweight Geometry

Finite-element-optimized casing walls remove unnecessary material while maintaining full load capacity, reducing installed weight by 15% versus previous-generation housings.

🔧 Keserasian & Rujukan Silang Peralatan

🔄 Cross-Reference Compatibility for EP01-672

The EP01-672 is engineered as a direct replacement or upgrade for gearboxes fitted to equipment from leading manufacturers including:

Rhino • LS Tractor • Fella • Sonalika • Branson • Dongfeng • John Deere • AGCO

Penafian: Nama jenama di atas dirujuk semata-mata untuk pengenalpastian keserasian. Ever-power Australia Mower Gearbox Co.,Ltd. tidak bergabung dengan, disokong oleh atau dibenarkan oleh mana-mana pengeluar tersenarai. Semua tanda dagangan adalah milik pemilik masing-masing.

📚 Panduan Pemilihan Kotak Gear

The correct gearbox specification depends on your tractor, implement, and field conditions. Evaluate these factors for the EP01-672:

📌 Katalog Standard vs Spesifikasi Tersuai
The EP01-672 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.
📌 Keserasian Jenis Aci Output
The EP01-672 features 1 3/8 Z6 / Optic axis 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.
📌 Pertimbangan Berat dan Pemasangan
At 18.5 Kg, the EP01-672 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.
📌 Matching Gear Ratio to Blade Tip Speed
For the EP01-672 with ratio(s) 1.92:1 / 1.47:1, 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 ÷ ratio. Multiply by blade diameter to get tip speed.
📌 Sizing Power Rating to Tractor PTO HP
The EP01-672 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.

🛠 Panduan Pemasangan & Persediaan

  1. 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.
  2. 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.
  3. Sapukan manik pengedap silikon RTV yang nipis dan sekata pada permukaan bebibir pelekap jika gasket pra-potong tidak disertakan dengan kotak gear baharu.
  4. 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.
  5. 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.
  6. Tanggalkan aci PTO traktor dan sokong alat pemotong rumput dengan selamat pada penyangga atau blok bicu sebelum memulakan prosedur pemasangan kotak gear.
  7. Bagi unit yang beratnya melebihi 25 kg, gunakan pengangkat rantai, kren enjin atau pengangkat dua orang untuk meletakkan kotak gear. Jangan sekali-kali cuba mengangkat kotak gear berat secara bersendirian.

❓ Soalan Lazim

❓ What gear oil specification does this gearbox require?

Use SAE 80W-90 or SAE 85W-140 GL-5 extreme-pressure gear oil under normal conditions. For sub-zero climates below -20 °C, a synthetic 75W-90 ensures proper cold-start flow. Always check the sight glass or dipstick before each shift.

❓ Which tractor brands are compatible?

Our gearboxes use standard PTO connections (1 3/8″ 6-spline or 1 3/4″ 20-spline) compatible with virtually every brand — John Deere, Kubota, Massey Ferguson, New Holland, Case IH, Kioti, Mahindra, and more.

❓ How noisy is this gearbox during operation?

Our spiral bevel designs produce 72-78 dB(A) at 1 metre under rated load — significantly quieter than straight-bevel alternatives (typically 82-88 dB). Operators notice a meaningful reduction in gear whine.

❓ What is the difference between ratio options?

Ratio determines the speed/torque trade-off at the output. 1:1 maintains PTO speed (high blade RPM); 1:1.93 nearly halves output speed while doubling torque. Choose based on your target blade tip speed and vegetation density.

❓ What is the lead time for standard models?

In-stock standard models ship within 3-5 business days. For models requiring custom ratios or configurations, typical lead time is 4-6 weeks. Rush production is available for urgent requirements.
