EP-AG135 Lawn Mower Gearbox

The EP-AG135 is a 50 HP, 1:1 ratio agricultural gearbox weighing only 16.5 kg — exceptional power density for its class. Pasture renovation contractors and seed farm operators choose the AG135 when they need a direct-drive unit that preserves full PTO speed for high-RPM finishing mower heads.

⭐ 主な特長とエンジニアリング上の利点

🔬

Multi-Position Bolt Pattern

Versatile mounting interface with tapped holes at 0°, 90°, and 180° orientations, fitting a wide range of implement frame geometries without adapter plates.

E-Coat + Powder Coat Finish

25 μm zinc-rich e-coat primer plus 80 μm polyester powder topcoat provides 1,000+ hours of ASTM B117 salt-spray corrosion resistance.

🚀

Heavy-Duty Triple-Lip Seals + Scraper

Three-lip shaft seals with external scraper rings prevent soil and moisture ingress even during tillage in waterlogged or heavily saturated ground.

💪

Dedicated Thrust Bearing Stage

Purpose-designed thrust bearings absorb the axial forces generated as tiller blades engage the soil, preventing shaft walk and premature seal extrusion.

Stainless Steel Breather Valve

Labyrinthed breather prevents pressure build-up during temperature swings while blocking water and dust ingress — a common failure point in cheaper gearboxes.

CNC-Bored Bearing Seats, IT6 Tolerance

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.

📚 ギアボックス選定ガイド

The EP-AG135 covers a specific performance envelope. Use these selection criteria to verify it aligns with your operational parameters:

📌出力軸タイプの互換性
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 — spline, taper, keyway, and flange — to match virtually any existing installation.
📌重量と取り付けに関する考慮事項
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.
📌 ギア比とブレード先端速度のマッチング
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 ÷ ratio. Multiply by blade diameter to get tip speed.
📌トラクターPTO馬力に対する出力定格の選定
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.
📌 540 RPM vs 1000 RPM PTO Selection
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 — the doubled speed will destroy bearings and gears within minutes.

🛠 インストールとセットアップガイド

  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.
  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.
  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.
  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.
  5. 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.
  6. 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.
  7. 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.

❓よくある質問

❓ Do you provide dimensional drawings?

Full technical drawings — mounting holes, shaft specs, envelope dimensions — are available for every model. Download from our product pages or request from our technical department at no charge.

❓ Do you offer technical support after purchase?

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.

❓ Is this gearbox safe to run at 1000 RPM PTO speed?

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.

❓ Can I mount this gearbox at non-standard angles?

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.

❓ How do I identify when my gearbox needs repair?

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.
