⭐ Key Features & Engineering Advantages
⚖
Quadruple-Barrier Environmental Sealing
Labyrinth + twin Viton FKM seals + armored debris shield achieve IP67, protecting against total submersion and high-pressure cleaning equipment.
🚀
Forced-Splash Oil Distribution
Gear-driven splash channels route lubricant to every bearing and mesh zone even on hillside slopes up to 35°, preventing dry-running at extreme operating angles.
💪
AISI 9310 Aircraft-Grade Gears
Vacuum-carburized, cryogenically treated gears reaching HRC 62-65 surface with a ductile core — the same metallurgy used in helicopter transmission gears.
⚙
99% Peak Efficiency, AGMA Class 12
Super-finished teeth ground to ≤ 0.2 μm Ra with class-leading accuracy, transmitting power with virtually zero parasitic friction at rated speed and load.
⚗
Hypoid Gear Precision Set
High-precision hypoid gears from 20MnCr5 steel, carburized and ground to AGMA Class 9, for smooth and quiet power transfer inside disc mower hubs.
🔒
Concentric Blade-Mount Hub
Precision-machined pilot diameter and balanced bolt circle ensure vibration-free disc rotation, maintaining uniform cutting height across the full mower bar width.

📚 Gearbox Selection Guide
The correct gearbox specification depends on your tractor, implement, and field conditions. Evaluate these factors for the EP-01-790:
🌾 Typical Application Scenarios
🌾 Mining site vegetation rehabilitation and control
🚘 Forestry site preparation and plantation row clearing
🌱 Stubble incorporation and green manure tillage
⛰ Municipal park and recreational reserve mowing
🌳 Silage paddock management and pasture renovation
🛠 Installation & Setup Guide
- 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.
- Disconnect the tractor PTO shaft and safely support the mower implement on jack stands or blocks before beginning the gearbox installation procedure.
- 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.
- 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.
- 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.
- 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.
