⭐ Belangrijkste kenmerken en technische voordelen

⚡

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.

🔨

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.

📚 Gids voor het kiezen van een versnellingsbak

The EP-1ZS-380 covers a specific performance envelope. Use these selection criteria to verify it aligns with your operational parameters:

📌 Output Shaft Type Compatibility
The EP-1ZS-380 features Spline 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.
📌 Weight and Mounting Considerations
At 42.5 Kg, the EP-1ZS-380 is designed for large-frame tractor implements and heavy-duty mowers. 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.
📌 Afstemming van de overbrengingsverhouding op de snelheid van de bladpunt
For the EP-1ZS-380 with ratio(s) 1:1.24, 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.
📌 Vermogensclassificatie afstemmen op aftakasvermogen (PTO) van de tractor
The EP-1ZS-380 is rated at 100 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.
📌 Keuze tussen 540 tpm en 1000 tpm aftakas
The EP-1ZS-380 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.

🛠 Installatie- en configuratiehandleiding

  1. 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.
  2. Na de eerste 10 bedrijfsuren alle bevestigingsbouten opnieuw vastdraaien volgens de specificaties en het oliepeil controleren. De eerste olieverversing uitvoeren na 50 bedrijfsuren.
  3. Koppel de aftakas van de tractor los en ondersteun het maaiwerktuig veilig met krikken of blokken voordat u begint met de installatie van de versnellingsbak.
  4. Voor units die meer dan 25 kg wegen, gebruik een kettingtakel, motortakel of een hijsinstallatie met twee personen om de versnellingsbak te positioneren. Probeer nooit zware versnellingsbakken in je eentje te tillen.
  5. Vul de versnellingsbak bij met de aanbevolen versnellingsbakolie (SAE 80W-90 of 85W-140 EP) tot het niveau dat is aangegeven op het kijkglas of de peilstok. Niet te veel bijvullen.
  6. Voordat u op vol vermogen gaat werken, doorloop een geleidelijke inloopperiode: 30 minuten op half gas, vervolgens 30 minuten op driekwart gas, voordat u het volledige aftakastoerental inschakelt.
  7. Controleer met een liniaal of de montageplaat van het werktuig vlak is. Eventuele krommingen van meer dan 0,5 mm moeten worden gecorrigeerd voordat de nieuwe versnellingsbak wordt gemonteerd.

❓ Veelgestelde vragen

❓ Do you offer technical support after purchase?

Yes. Our technical team provides installation guidance, troubleshooting support, and maintenance advice via phone, email, and video call. We also offer on-site training for fleet operators and dealer technicians.

❓ 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.

Third unit purchased for our growing fleet. Consistent quality every time. Their factory clearly has disciplined production processes.

★★★★★

📍 Punjab, India

Our mechanic was impressed by the machining quality when he opened the box. Everything was precisely finished and well-protected for shipping.

★★★★★

📍 Free State, South Africa

The split-line O-ring seal is a real bonus. Saves us time in the workshop and lets us spend more hours in the paddock. Great design.

★★★★☆

📍 Otago, New Zealand

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

★★★★☆

📍 Normandy, France

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.
