EP20.100J.01WW Lawn Mower Gearbox

EP20.100J.01WW Lawn Mower Gearbox

Despite weighing only 16 kg, the EP20.100J.01WW handles 100-120 HP through its 1:1 ratio and module 5.4 gear set — an industry-leading power-to-weight ratio. High-performance mower OEMs and racing-turf maintenance teams specify this model when minimum implement weight is as critical as maximum power throughput.

⭐ 主な特長とエンジニアリング上の利点

🔄

マグネット式排水栓

ネオジム製ドレンプラグは、慣らし運転時や通常運転時に発生する鉄系摩耗粉を捕捉し、ギアやベアリングを摩耗粉の再循環による損傷から保護します。

🔨

大容量オイルサンプ設計

30%は標準モデルに比べてオイル容量が大きく、高負荷での草刈り作業が続く際の作動温度を8～12℃下げ、潤滑油の寿命を延ばします。

🌡

分割式Oリングシール

精密加工されたハウジング分割ラインとフッ素樹脂製Oリングにより、従来の紙製またはRTVガスケット接合部におけるガスケットの伸びや再締め付けの必要性がなくなります。

🛠

低バックラッシュプリロードアセンブリ

ベアリングの予圧と制御されたギアのかみ合いクリアランスにより、全体のバックラッシュは0.08mm未満に抑えられ、これは逆負荷用途や精密切削作業において非常に重要です。

🔬

Redundant Lubrication Groove System

Machined oil distribution grooves in the housing bore supplement splash lubrication, providing a secondary oil path to bearings if sump level drops slightly below specification.

⚖

Reinforced Grey Cast Iron Housing

HT250-grade grey iron casing with 14 mm wall thickness, ribbed for vibration damping and thermal dissipation, resisting cracking from rock strikes at mowing speed.

📚 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 EP20.100J.01WW:

📌 ギア比とブレード先端速度のマッチング
For the EP20.100J.01WW with ratio(s) 1:1, 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 EP20.100J.01WW is rated at 100 / 120 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 対 1000 RPM PTO の選択
The EP20.100J.01WW 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.
📌鋳鉄製ハウジング vs アルミニウム製ハウジング
The EP20.100J.01WW 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 EP20.100J.01WW 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. Ensure the PTO shaft has at least 50% spline overlap in all operating positions. Inadequate overlap causes rapid spline wear and potential shaft separation.
  2. Record the installation date, tractor hour meter reading, and gearbox serial number in your maintenance log for warranty and service interval tracking.
  3. 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.
  4. 取り付けボルトはすべて、まず指で軽く締めてから、十字形（星形）になるように規定トルクで締め付け、均等に締め付けます。標準的なトルク値は、ボルトのサイズによって80～120Nmです。
  5. 作業機を持ち上げ、ブレードが地面から離れている状態で、PTOを低速アイドル回転で作動させます。異音がないか、振動やオイル漏れがないかを確認してください。
  6. 3点ヒッチが故障した場合にギアボックスが地面に接触しないよう、芝刈り機の作業装置安全チェーンまたは拘束装置が正しく接続されていることを確認してください。
  7. 新しいギアボックスにプレカットガスケットが付属していない場合は、取り付けフランジ面にRTVシリコンシーラントを薄く均一に塗布してください。

❓よくある質問

❓ 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.

❓ これはマルチング用途に適していますか？

はい。当社のギアボックスは、マルチング式芝刈り機や草刈り機に広く使用されています。マルチング作業には、実際のP​​TO出力よりも定格出力の高い25-30%モデルをお選びください。これにより、マルチング作業特有の断続的な衝撃荷重に対する安全マージンが確保されます。

❓ どのような品質検査を実施していますか？

すべてのギアボックスは、出荷前に100%寸法検査（CMM）、歯車歯形状検証（グリーソンアナライザー）、硬度試験、オイル漏れ試験、および無負荷慣らし運転試験を受けます。

⭐ お客様の声と現場レポート

★★★★★

📍 Tasmania, Australia

The cooling fin design is a real bonus. Saves us time in the workshop and lets us spend more hours in the paddock. Great design.

★★★★★

📍 スペイン、カスティーリャ地方

Oil change was simple thanks to the drain and fill locations being well-positioned. Small details like this show engineering thought.

★★★★★

📍アルゼンチン、メンドーサ

We needed a gearbox fast after a mid-season failure. This arrived in 5 days, bolted on in an hour, and has been perfect since.

★★★★☆

📍 ドイツ、バイエルン州

Bolt pattern matched my slasher perfectly. Quieter than the original gearbox it replaced and the oil stays clean much longer between changes.

★★★★☆

📍 Thessaly, Greece

Installed on our rotary cutter for sugarcane/crop field work. Oil seal quality is excellent — no leakage despite dusty and humid conditions.
