⭐ Viktiga funktioner och tekniska fördelar
💥 Anti-Vibration Mounting
Precision-machined mating surfaces and oversized mounting bolts reduce gear mesh vibration by 40% compared to spur gear designs, protecting both the gearbox and tiller frame.
🌡️ All-Season Operation
Rated for continuous operation from -20°C to +110°C with synthetic EP gear lubricant, supporting spring preparation through autumn harvest tilling cycles.
📈 Adjustable Column Lengths
Available with multiple column length options to accommodate different tiller widths and tractor three-point hitch configurations.
⚙ Heavy-Duty Spiral Bevel Gears
Manufactured from 20CrMnTi alloy steel with carburizing treatment to 58-62 HRC surface hardness, providing exceptional wear resistance during high-torque soil cultivation at depths up to 300mm.
🛡 Reinforced Cast Iron Body
QT500-7 ductile cast iron housing engineered to withstand repeated vibration and impact loads generated during rotary tilling of compacted and rocky soils.
💧 Triple-Sealed Against Soil Ingress
Three-stage sealing system with labyrinth seal, double-lip oil seal, and external dust cap provides complete protection against fine soil particles and moisture penetration.

🔎 Urvals- och storleksguide
Choosing the right cultivator gearbox affects tilling depth, soil finish, and fuel efficiency. Use these criteria to determine if the EP20100.131.00 meets your needs:
⚙ Matcha utväxlingsförhållandet till tillämpningen
Förhållande 1:1 till 1:1,5 — Minimal hastighetsreduktion; används när redskapets blad-/pinnarhastighet ska matcha kraftuttagsvarvtalet noggrant. Vanligt för finklippare och lättare applikationer.
Förhållande 1:1,5 till 1:2 — Måttlig vridmomentökning med proportionell hastighetsminskning. Lämplig för vanliga rotorklippare, medeltunga gräsklippare och universalredskap.
Förhållande 1:2,5 till 1:3+ — Hög vridmomentförstärkning för tunga laster. Oumbärligt för rotorkultivatorer, grävmaskiner och röjsågar som arbetar i tätt material.
⚡ Matcha traktorns hk med växellådans effekt
Välj alltid en växellåda med en nominell effekt (hk) som är lika med eller större än traktorns maximala kraftuttagseffekt. Att köra en växellåda över sin nominella effekt orsakar överhettning, snabbare kugghjulsslitage och för tidigt haveri. Som en god praxis, bibehåll en säkerhetsmarginal på 10-20% över din faktiska driftsbelastning.
🔄 540 varv/min vs 1000 varv/min — Vilket kraftuttagsvarvtal?
540 varv/min kraftuttag is the standard for most agricultural implements under 100HP. The EP20100.131.00 is designed for 540 RPM input. 1000 varv/min kraftuttag används på traktorer med högre hästkrafter (vanligtvis 75 hk+) och kräver en växellåda som är specifikt klassad för den hastigheten. Anslut inte en växellåda på 540 varv/min till ett kraftuttag på 1000 varv/min utan en hastighetsadapter.
🛡 Aluminium kontra gjutjärnshölje
AluminiumBäst för kompakttraktorer under 25 hk, kustnära/fuktiga miljöer och tillämpningar där vikten spelar roll (gräsklippare, små rotorklippare). Utmärkt värmeavledning och korrosionsbeständighet.
GjutjärnKrävs för medeltunga till tunga tillämpningar över 25 hk. Överlägsen stöttålighet och strukturell styvhet för röjning, tung gräsklippning, kultivering och grävning av efterhål.
🔧 Standard vs. specialväxellåda
Våra standardmodeller täcker 90% av vanliga jordbruksväxellådor med monterings- och axeldimensioner enligt branschstandard. För OEM-tillverkare eller unika redskapsdesigner som kräver icke-standardiserade utväxlingar, axelkonfigurationer eller monteringsmönster erbjuder vi fullständig kundanpassad tillverkning med en MOQ på så lite som 50 enheter.

🛠 Installations- och installationsguide
Follow these steps to install the EP20100.131.00 on your implement. Always refer to the included instruction manual for model-specific torque values and safety precautions.
- Park the tractor on level ground, lower the cultivator fully, and disconnect the PTO shaft. Ensure the engine is off and hydraulics are depressurized.
- Support the cultivator frame securely with jack stands. Remove the column-to-frame mounting bolts and disconnect the gearbox output from the rotor drive.
- Unbolt and remove the old gearbox assembly. Note the column length and any spacer/shim positions for reassembly reference.
- Clean all mating surfaces on the cultivator frame. Install any required gaskets or O-rings supplied with the new EP20100.131.00 gearbox.
- Mount the new gearbox to the frame, inserting and hand-tightening bolts first. Verify shaft alignment with the rotor drive before final torquing to 80-100 Nm.
- Reconnect the PTO shaft to the gearbox input. Verify full spline engagement depth and install the shear bolt or overload clutch.
- Fill with the recommended gear oil to the level plug. Run at idle PTO speed for 10 minutes without ground engagement to bed in the gears.
❓ Vanliga frågor
Can I use this gearbox for a power harrow?
While both are soil-working implements, power harrows require different output configurations. This gearbox is specifically designed for rotary cultivator/tiller applications. Contact us for our power harrow gearbox range.
What maintenance schedule do you recommend?
Change oil after first 50 hours, then every 150 operating hours. Inspect seals for soil ingress after each use. Grease the input shaft spline every 100 hours. Check bolt torques monthly during heavy-use seasons.
How do I handle a seized gearbox?
First, drain the oil and inspect for metal contamination. If gears are not damaged, flush with diesel fuel, refill with fresh oil, and run at no-load for 5 minutes. If metal fragments are present, the gearbox requires professional rebuild or replacement.
Does operating depth affect gearbox life?
Yes. Deeper tilling (200mm+) significantly increases load on the gearbox. Ensure your tractor PTO horsepower exceeds the gearbox rated power by at least 20% when operating at maximum depth in heavy soils.
What warranty coverage applies?
All EP cultivator gearboxes carry a 12-month warranty against manufacturing defects. Damage from overloading, incorrect oil, or improper installation is excluded.
