⭐ Key Features & Engineering Advantages
🔬
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.

📚 Gearbox Selection Guide
The EP-AG135 covers a specific performance envelope. Use these selection criteria to verify it aligns with your operational parameters:
🌾 Typical Application Scenarios
🌾 Flail mulching of pruning residue in fruit plantations
🚘 Orchard and vineyard floor maintenance between rows
🌱 Mining site vegetation rehabilitation and control
⛰ Forestry site preparation and plantation row clearing
🌳 Stubble incorporation and green manure tillage
🛠 Installation & Setup Guide
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
