EP-RC33 Lawn Mower Gearbox

The EP-RC33 offers three switchable ratios (1:1.47, 1:1.69, 1:1.93) at 30 HP in a 26 kg housing. Property maintenance contractors and rural fire authorities choose the RC33 because it lets them adapt blade speed to changing vegetation — from fine lawn finish to thick seasonal grass and light scrub — with a single gearbox.

説明


Built to Last: EP-RC33 Multi-Ratio Rotary Cutter Gearbox

EP-RC33 is built for the operator who values uptime above all else. This agricultural gearbox handles 30 / 30 / 30 HP through precision-machined spiral bevel gears, supported by premium bearings and multi-stage sealing for maximum service life.

⭐ 主な特長とエンジニアリング上の利点

🚀

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.

Standard 1 3/8″ 6-Spline PTO Input

Industry-standard input spline accepts all 540 RPM PTO shafts, ensuring bolt-on compatibility with tractors from 15 HP sub-compacts to 50 HP utility models.

Induction-Hardened Output Shaft

Output shaft journals hardened to HRC 50-55 via controlled induction heating, extending bearing seat life beyond 3,000 operating hours before re-machining is needed.

🔒

Triple-Stage Shaft Sealing

Inner labyrinth + double-lip FKM seal + external V-ring slinger form a three-barrier defense against water, mud, and fine dust penetrating to the bearing cavities.

Integrated External Cooling Fins

35% additional surface area from machined cooling ribs accelerates heat rejection, keeping oil temperature below 80 °C during sustained full-load summer mowing.

📚 ギアボックス選定ガイド

The EP-RC33 covers a specific performance envelope. Use these selection criteria to verify it aligns with your operational parameters:

📌出力軸タイプの互換性
The EP-RC33 features 1 3/8 Z6 / Optic axis 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.
📌重量と取り付けに関する考慮事項
At 26 Kg, the EP-RC33 is designed for compact and sub-compact tractor implements. Confirm your implement frame and three-point hitch can support this weight plus the weight of the blade assembly. Mounting bolt pattern and orientation should match your existing layout.
📌 ギア比とブレード先端速度のマッチング
For the EP-RC33 with ratio(s) 1:1.93 / 1:1.69 / 1:1.47, 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-RC33 is rated at 30 / 30 / 30 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-RC33 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.

🛠 インストールとセットアップガイド

  1. 全負荷運転を行う前に、段階的な慣らし運転を行ってください。まず、スロットルを半分開けて30分間運転し、次にスロットルを4分の3開けて30分間運転してから、PTOを全開速度で運転してください。
  2. 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。
  3. 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。
  4. 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。
  5. 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。
  6. 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。
  7. 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。

❓よくある質問

❓ Is this gearbox safe to run at 1000 RPM PTO speed?

This unit is rated for 540 RPM input. Operating at 1000 RPM without the correct gear set will over-speed bearings and gears, causing rapid failure. Contact our team if you need a 1000 RPM-rated configuration.

❓ Can I mount this gearbox at non-standard angles?

Most models are designed for vertical or horizontal output as specified. Mounting at unusual angles can affect oil distribution. Contact our engineering team to confirm suitability before installing in a non-standard orientation.

❓ How do I identify when my gearbox needs repair?

Warning signs: unusual grinding or whining noise, increased vibration, oil leakage, metallic particles on the magnetic drain plug, elevated operating temperature, or detectable play in the output shaft.

❓ Can I visit your manufacturing facility?

We welcome factory visits and audits from prospective partners. Our production facility is equipped for full tours, and we can arrange local transport from the nearest airport. Contact us to schedule a convenient date.

❓ 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.
