⭐ Key Features & Engineering Advantages

🔬

Integrated Overload Shear Hub

Built-in shear bolt hub on the output protects the entire gear train from catastrophic damage when blades strike immovable objects like buried concrete or steel.

⚖

Thermo-Compensating Bearing Spacer

Calibrated aluminium spacer between bearing sets expands proportionally with temperature, maintaining optimal preload from cold start through peak operating temperature.

🚀

CNC-Machined Spiral Bevel Gears

Gears cut from 20CrMnTi alloy on Gleason CNC generators, case-carburized to HRC 58-62 with 1.2 mm case depth for 10+ million cycle fatigue life under rated torque.

💪

96-98% Power Transmission Efficiency

Precision-lapped tooth contact patterns reduce mesh friction losses to under 4%, delivering near-full PTO horsepower to the blade assembly with minimal heat build-up.

⚙

Pre-Filled EP90 Gear Lubricant

Ships factory-filled with extreme-pressure SAE 90 gear oil and includes a clear sight glass for instant oil-level verification before each operating session.

⚗

QT450-10 Ductile Iron Shell

Nodular graphite iron housing absorbs 40% more impact energy than grey iron, protecting internal components when the mower strikes concealed rocks or fence posts.

📚 Gearbox Selection Guide

A well-matched gearbox delivers years of trouble-free service. Follow this guide to confirm the EP-RTS50 is the optimal choice for your needs:

📌 Sizing Power Rating to Tractor PTO HP
The EP-RTS50 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-RTS50 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.
📌 Cast Iron Housing vs Aluminium Housing
The EP-RTS50 uses a grey cast iron housing. Cast iron excels in vibration damping, impact resistance, and heat dissipation — ideal for rough, rocky mowing conditions. Aluminium is lighter and more corrosion-resistant, better suited to wet environments and weight-sensitive implements.
📌 Standard Catalog vs Custom Specification
The EP-RTS50 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.
📌 Output Shaft Type Compatibility
The EP-RTS50 features Flange mount 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.

🌾 Typical Application Scenarios

🛠 Installation & Setup Guide

  1. 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.
  2. Disconnect the tractor PTO shaft and safely support the mower implement on jack stands or blocks before beginning the gearbox installation procedure.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. Use Nord-Lock washers or thread-locking compound on all mounting bolts to prevent vibration-induced loosening during operation.

❓ Frequently Asked Questions

❓ What is the recommended oil change schedule?

Drain and replace oil after the first 50 hours of break-in. After that, change oil every 200-300 hours or at least once per season. Always drain warm oil for complete evacuation and inspect the magnetic drain plug for metallic debris.

❓ Do you manufacture custom ratios and shaft types?

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.

❓ What PTO shaft should I pair with this gearbox?

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.

❓ How does your pricing compare to genuine OEM parts?

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.

❓ What gear oil specification does this gearbox require?

Use SAE 80W-90 or SAE 85W-140 GL-5 extreme-pressure gear oil under normal conditions. For sub-zero climates below -20 °C, a synthetic 75W-90 ensures proper cold-start flow. Always check the sight glass or dipstick before each shift.

⭐ Customer Reviews & Field Reports

★★★★★

📍 Victoria, Australia

We fitted six of these across our fleet. Every single unit has performed flawlessly through two complete cutting seasons.

★★★★★

📍 Poltava, Ukraine

Excellent for paddock clearing. The sealed bearings makes maintenance easy and keeps unplanned downtime to a minimum.

★★★★★

📍 Córdoba, Argentina

Runs noticeably cooler than the old gearbox it replaced. The improved cooling design and better oil volume are making a real difference.

★★★★☆

📍 Bordeaux, France

We tested this against a competitor unit side by side. This one runs quieter, stays cooler, and the oil stayed cleaner over 200 hours.

★★★★☆

📍 Adana, Turkey

First purchase from this manufacturer and I am thoroughly impressed. Build quality, documentation, and support were all top-notch.
