⭐ Key Features & Engineering Advantages
🌡
Interference-Fit Bearing Installation
All bearings installed with controlled interference fit using induction heating, preventing the spinning-in-bore failures common in slip-fit assemblies.
🛠
Hardened Shift Fork Mechanism
For multi-ratio models: induction-hardened shift fork and detent system provides positive gear engagement with tactile confirmation, preventing half-engagement damage.
🔬
Hot-Dip Galvanized Mounting Hardware
Grade 10.9 mounting bolts hot-dip galvanized to AS/NZS 4680, resisting corrosion in coastal and high-humidity farming regions like northern Queensland and Waikato.
⚖
Field-Rebuildable Modular Design
All internal components — gears, bearings, seals, shafts — are individually replaceable in the field with standard hand tools, eliminating the need to send units away for factory rebuild.
🚀
Dual-Lip NBR Oil Seals
Twin-lip nitrile seals with integrated dust excluder on every shaft exit, rated to IP65, preventing moisture and crop debris from entering the gear chamber.
💪
Optimized Lightweight Geometry
Finite-element-optimized casing walls remove unnecessary material while maintaining full load capacity, reducing installed weight by 15% versus previous-generation housings.

📚 Gearbox Selection Guide
The correct gearbox specification depends on your tractor, implement, and field conditions. Evaluate these factors for the EP01-672:
🌾 Typical Application Scenarios
🌾 Municipal park and recreational reserve mowing
🚘 Silage paddock management and pasture renovation
🌱 Construction site vegetation clearing and preparation
⛰ Roadside and highway verge vegetation management
🌳 Pipeline and powerline easement clearing
🛠 Installation & Setup Guide
- 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.
- 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.
