⭐ Key Features & Engineering Advantages<\/h2>\n
\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

\n

🔄<\/p>\n

Laser-Etched Traceability Code<\/h4>\n

Every housing is laser-marked with a unique serial number linking to full material, heat-treatment, and inspection records for complete supply-chain traceability.<\/p>\n<\/div>\n

\n

🔨<\/p>\n

Balanced Gear Set Assembly<\/h4>\n

Complete gear sets are dynamically balanced as a matched pair to ISO G6.3, reducing transmitted vibration to the mower frame and extending component fatigue life.<\/p>\n<\/div>\n

\n

🌡<\/p>\n

Integrated Overload Shear Hub<\/h4>\n

Built-in shear bolt hub on the output protects the entire gear train from catastrophic damage when blades strike immovable objects like buried concrete or steel.<\/p>\n<\/div>\n

\n

🛠<\/p>\n

Thermo-Compensating Bearing Spacer<\/h4>\n

Calibrated aluminium spacer between bearing sets expands proportionally with temperature, maintaining optimal preload from cold start through peak operating temperature.<\/p>\n<\/div>\n<\/div>\n

📚 Gearbox Selection Guide<\/h2>\n

Getting gearbox selection right the first time saves money and headaches. Here is a systematic approach to specifying the EP-MDH-65:<\/p>\n

\n📌 Cast Iron Housing vs Aluminium Housing<\/summary>\n
The EP-MDH-65 uses a aluminium alloy or cast iron housing. Cast iron excels in vibration damping, impact resistance, and heat dissipation \u2014 ideal for rough, rocky mowing conditions. Aluminium is lighter and more corrosion-resistant, better suited to wet environments and weight-sensitive implements.<\/div>\n<\/details>\n
\n📌 Standard Catalog vs Custom Specification<\/summary>\n
The EP-MDH-65 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-MDH-65 features Flange mount hub 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 22 Kg (approx.), the EP-MDH-65 is designed for disc mower cutter bars. 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-MDH-65 with ratio(s) N\/A (Hub Drive), 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

🛠 Installation & Setup Guide<\/h2>\n
    \n
  1. Use Nord-Lock washers or thread-locking compound on all mounting bolts to prevent vibration-induced loosening during operation.<\/li>\n
  2. 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
  3. Clean the implement mounting surface thoroughly, removing all rust, old gasket material, paint flakes, and debris that could prevent flush contact with the gearbox flange.<\/li>\n
  4. Position the gearbox onto the mounting studs or bolt holes, verifying the input shaft faces the tractor PTO and the output shaft aligns with the blade hub or rotor.<\/li>\n
  5. Ensure the PTO shaft has at least 50% spline overlap in all operating positions. Inadequate overlap causes rapid spline wear and potential shaft separation.<\/li>\n
  6. Record the installation date, tractor hour meter reading, and gearbox serial number in your maintenance log for warranty and service interval tracking.<\/li>\n
  7. 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<\/ol>\n

    ❓ Frequently Asked Questions<\/h2>\n
    \n
    \n❓ What quality inspections do you perform?<\/summary>\n
    \n

    Every gearbox undergoes 100% dimensional inspection (CMM), gear tooth geometry verification (Gleason analyzer), hardness testing, oil-leak testing, and no-load run-in testing before shipment.<\/p>\n<\/div>\n<\/details>\n

    \n❓ What warranty do you provide?<\/summary>\n
    \n

    Every gearbox ships with a 12-month warranty covering material and workmanship defects under normal operating conditions. Warranty claims are handled through our dealer network with replacement units dispatched within 48 hours of approval.<\/p>\n<\/div>\n<\/details>\n

    \n❓ How do I determine the correct model for my mower?<\/summary>\n
    \n

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

    \n❓ Is synthetic gear oil recommended?<\/summary>\n
    \n

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

    \n❓ What shipping methods are available?<\/summary>\n
    \n

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