📚 Gearbox Selection Guide<\/h2>\n

Choosing the right mower gearbox is critical for implement performance and longevity. Use the following criteria when evaluating the EP-140:<\/p>\n

\n📌 Matching Gear Ratio to Blade Tip Speed<\/summary>\n
For the EP-140 with ratio(s) 1:1.5 \/ 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📌 Sizing Power Rating to Tractor PTO HP<\/summary>\n
The EP-140 is rated at 60 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📌 540 RPM vs 1000 RPM PTO Selection<\/summary>\n
The EP-140 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
\n📌 Cast Iron Housing vs Aluminium Housing<\/summary>\n
The EP-140 uses a grey 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-140 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

🛠 Installation & Setup Guide<\/h2>\n
    \n
  1. 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
  2. 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
  3. 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
  4. Apply a thin, even bead of RTV silicone sealant to the mounting flange face if a pre-cut gasket is not included with the new gearbox.<\/li>\n
  5. Connect the PTO drive shaft to the gearbox input spline. Push the shaft on fully and verify it telescopes freely through the complete range of three-point hitch travel.<\/li>\n
  6. After the first 10 hours of operation, re-torque all mounting bolts to specification and verify oil level. Perform the first oil drain and refill at 50 hours.<\/li>\n
  7. Disconnect the tractor PTO shaft and safely support the mower implement on jack stands or blocks before beginning the gearbox installation procedure.<\/li>\n<\/ol>\n

    ❓ Frequently Asked Questions<\/h2>\n
    \n
    \n❓ Which tractor brands are compatible?<\/summary>\n
    \n

    Our gearboxes use standard PTO connections (1 3\/8″ 6-spline or 1 3\/4″ 20-spline) compatible with virtually every brand \u2014 John Deere, Kubota, Massey Ferguson, New Holland, Case IH, Kioti, Mahindra, and more.<\/p>\n<\/div>\n<\/details>\n

    \n❓ How noisy is this gearbox during operation?<\/summary>\n
    \n

    Our spiral bevel designs produce 72-78 dB(A) at 1 metre under rated load \u2014 significantly quieter than straight-bevel alternatives (typically 82-88 dB). Operators notice a meaningful reduction in gear whine.<\/p>\n<\/div>\n<\/details>\n

    \n❓ What is the difference between ratio options?<\/summary>\n
    \n

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

    \n❓ What is the lead time for standard models?<\/summary>\n
    \n

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

    \n❓ How do I select the right gear ratio?<\/summary>\n
    \n

    Match the ratio to your blade tip speed target. Lower ratios (e.g. 1:1) give higher blade RPM for finish mowing; higher ratios (e.g. 1:1.93 or above) trade speed for torque, ideal for thick brush. Calculate: output RPM = input RPM \u00f7 ratio.<\/p>\n<\/div>\n<\/details>\n<\/div>\n
