EP-RC61T Lawn Mower Gearbox

EP-RC61T Lawn Mower Gearbox

With four selectable ratios (1:1 to 1:1.93) and 60 HP capacity, the EP-RC61T is designed for operators who run multiple implement types from one tractor. Custom harvesters and agri-service businesses reduce downtime and inventory by keeping a single EP-RC61T on hand instead of stocking four separate gearboxes.

⭐ 主な特長とエンジニアリング上の利点

⚖

Tip-Relief Quiet Gear Profile

Tooth profile modifications (tip relief + lead crowning) reduce gear-mesh noise by 6 dB versus standard straight bevel designs, improving operator comfort.

🚀

Abrasion-Resistant Cast Housing

Extra-thick grey iron walls with hardened mounting faces, resisting the abrasive wear caused by constant soil contact during deep tillage operations.

💪

Bolt-On Precision Flange Mount

Machined flange with dowel pin locations for accurate, repeatable tiller frame alignment, eliminating vibration-inducing misalignment during extended tillage runs.

⚙

Gear-Ground Tooth Flanks, Ra 0.5 μm

Post-heat-treatment gear grinding achieves consistent surface finish and AGMA Class 9 geometry, reducing running-in wear and extending time to first service.

⚗

Hardened Dowel-Pin Alignment

Two precision ground dowel pins locate the housing halves within 0.02 mm, guaranteeing gear centre distance accuracy and eliminating assembly-induced backlash.

🔒

Zinc Flake Anti-Corrosion Fasteners

All external bolts finished with zinc-flake coating (Delta-Protekt) rated for 720 hours of salt spray, preventing seized fasteners during later disassembly.

📚 ギアボックス選定ガイド

Choosing the right mower gearbox is critical for implement performance and longevity. Use the following criteria when evaluating the EP-RC61T:

📌 ギア比とブレード先端速度のマッチング
For the EP-RC61T with ratio(s) 1:1 / 1:1.21 / 1:1.46 / 1:1.93, 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-RC61T is rated at 60 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-RC61T 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-RC61T 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.
📌 標準カタログ vs カスタム仕様
The EP-RC61T 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.

🛠 インストールとセットアップガイド

  1. 定規を使って、作業機の取り付け面が平坦かどうかを点検してください。0.5mmを超える歪みがある場合は、新しいギアボックスを取り付ける前に修正する必要があります。
  2. 運転中の振動による緩みを防ぐため、すべての取り付けボルトにNord-Lockワッシャーまたはねじロック剤を使用してください。
  3. ギアボックスを無負荷状態で5～10分間運転した後、停止させてオイルレベルを再確認してください。新しいシールやベアリングは、初期段階で少量のオイルを吸収することがよくあります。
  4. 作業機の取り付け面を徹底的に清掃し、錆、古いガスケット材、塗料の剥がれ、およびギアボックスフランジとの密着を妨げる可能性のある破片をすべて取り除きます。
  5. ギアボックスをマウントスタッドまたはボルト穴に配置し、入力シャフトがトラクターのPTOに面し、出力シャフトがブレードハブまたはローターと一直線になっていることを確認します。
  6. PTOシャフトは、すべての動作位置において、少なくとも50%のスプライン重なりを確保してください。重なりが不十分な場合、スプラインの摩耗が急速に進み、シャフトが分離する可能性があります。
  7. Record the installation date, tractor hour meter reading, and gearbox serial number in your maintenance log for warranty and service interval tracking.

❓よくある質問

❓ What is the difference between ratio options?

Ratio determines the speed/torque trade-off at the output. 1:1 maintains PTO speed (high blade RPM); 1:1.93 nearly halves output speed while doubling torque. Choose based on your target blade tip speed and vegetation density.

❓ What is the lead time for standard models?

In-stock standard models ship within 3-5 business days. For models requiring custom ratios or configurations, typical lead time is 4-6 weeks. Rush production is available for urgent requirements.

❓ How do I select the right gear ratio?

Match the ratio to your blade tip speed target. Lower ratios (e.g. 1:1) give higher blade RPM for finish mowing; higher ratios (e.g. 1:1.93 or above) trade speed for torque, ideal for thick brush. Calculate: output RPM = input RPM ÷ ratio.

❓ What is the expected operational lifespan?

With proper maintenance, our gearboxes typically deliver 3,000 to 5,000 operating hours. Many units in the field have exceeded 6,000 hours. Lifespan depends on operating load, maintenance compliance, and field conditions.

❓ Is this suitable for mulching applications?

Yes. Our gearboxes are widely used on mulching mowers and brush cutters. For mulching, select a model rated 25-30% above your actual PTO horsepower to provide a safety margin against the intermittent shock loads typical of mulching.

⭐ お客様の声と現場レポート

★★★★★

📍 Western Australia, Australia

We ordered in bulk for our dealer network. Customer return rate is near zero. That speaks volumes about reliability.

★★★★★

📍 Bordeaux, France

Fast shipping, professional packaging, and the gearbox itself is built like a tank. Highly recommended for serious agricultural work.

★★★★★

📍 Adana, Turkey

Installed on a disc mower that sees 8+ hours of use per day during season. Absolutely dependable. That is all I ask of a gearbox.

★★★★☆

📍 Saskatchewan, Canada

We maintain 40+ mowers for council contracts. Switching to this brand has reduced our gearbox failure rate by over 60 percent.

★★★★☆

📍 Hokkaido, Japan

Running in extreme cold (-25 °C) winters and hot summers. Synthetic oil in this gearbox handles both extremes without issue.
