📚 Gearbox Selection Guide<\/h2>\n

The correct gearbox specification depends on your tractor, implement, and field conditions. Evaluate these factors for the EP-01-790:<\/p>\n

\n📌 Standard Catalog vs Custom Specification<\/summary>\n
The EP-01-790 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-01-790 features 1 3\/8 Z6 \/ Keyway 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, the EP-01-790 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📌 Matching Gear Ratio to Blade Tip Speed<\/summary>\n
For the EP-01-790 with ratio(s) 1:1.92 \/ 1:2.5, 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-01-790 is rated at 40 \/ 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

🛠 Installation & Setup Guide<\/h2>\n
    \n
  1. 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
  2. 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
  3. Disconnect the tractor PTO shaft and safely support the mower implement on jack stands or blocks before beginning the gearbox installation procedure.<\/li>\n
  4. For units weighing over 25 kg, use a chain hoist, engine crane, or two-person lift to position the gearbox. Never attempt to lift heavy gearboxes solo.<\/li>\n
  5. Fill the gearbox with the recommended gear oil (SAE 80W-90 or 85W-140 EP) to the level indicated on the sight glass or dipstick. Do not overfill.<\/li>\n
  6. 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
  7. 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<\/ol>\n

    ❓ Frequently Asked Questions<\/h2>\n
    \n
    \n❓ Do you manufacture custom ratios and shaft types?<\/summary>\n
    \n

    Absolutely. We offer custom gear ratios, shaft profiles, and mounting configurations. Minimum order quantities apply for fully custom designs. Lead time is typically 4-6 weeks from order confirmation.<\/p>\n<\/div>\n<\/details>\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❓ What gear oil specification does this gearbox require?<\/summary>\n
    \n

    Use SAE 80W-90 or SAE 85W-140 GL-5 extreme-pressure gear oil under normal conditions. For sub-zero climates below -20 \u00b0C, a synthetic 75W-90 ensures proper cold-start flow. Always check the sight glass or dipstick before each shift.<\/p>\n<\/div>\n<\/details>\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<\/div>\n
