⭐ Główne cechy i zalety inżynieryjne
⚙ 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.
⚡ Optimized for High-Torque Tilling
3:1 reduction ratio amplifies tractor PTO torque by 300%, delivering the sustained rotational force required to break through hardpan, clay, and heavily compacted field soils.
🔧 Universal Tiller Fitment
Input and output shaft specifications match standard rotary cultivator mounting dimensions used across European, Japanese, and Chinese tiller brands.
💥 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.

🔎 Przewodnik po wyborze i rozmiarach
Matching a rotary cultivator gearbox to your tilling requirements involves balancing torque multiplication, working speed, and soil conditions. Here is how to evaluate the EP-30:
⚙ Dopasowanie przełożenia do zastosowania
Stosunek 1:1 do 1:1,5 — Minimalna redukcja prędkości; stosowana, gdy prędkość ostrza/zębów narzędzia powinna być zbliżona do prędkości WOM. Typowe dla kosiarek wykańczających i lekkich zastosowań.
Stosunek 1:1,5 do 1:2 — Umiarkowany wzrost momentu obrotowego z proporcjonalnym spadkiem prędkości. Nadaje się do standardowych kosiarek obrotowych, kosiarek o średniej mocy i narzędzi ogólnego zastosowania.
Stosunek 1:2,5 do 1:3+ — Wysokie wzmocnienie momentu obrotowego przy dużych obciążeniach. Niezbędne dla kultywatorów obrotowych, koparek do dołków i podkaszarek pracujących w gęstym materiale.
⚡ Dopasowanie mocy ciągnika do mocy skrzyni biegów
Zawsze wybieraj przekładnię o mocy znamionowej (KM) równej lub większej od maksymalnej mocy wyjściowej WOM Twojego ciągnika. Praca przekładni z mocą przekraczającą moc znamionową powoduje przegrzewanie, przyspieszone zużycie przekładni i przedwczesną awarię. Zaleca się zachowanie marginesu bezpieczeństwa 10-20% powyżej rzeczywistego obciążenia roboczego.
🔄 540 obr./min czy 1000 obr./min — która prędkość WOM?
WOM 540 obr./min is the standard for most agricultural implements under 100HP. The EP-30 is designed for 540 RPM input. WOM 1000 obr./min jest stosowany w ciągnikach o większej mocy (zazwyczaj 75 KM i więcej) i wymaga skrzyni biegów specjalnie przystosowanej do tej prędkości. Nie podłączaj skrzyni biegów 540 obr./min do WOM o prędkości 1000 obr./min bez adaptera prędkości.
🛡 Obudowa aluminiowa kontra żeliwna
Aluminium:Najlepszy do kompaktowych ciągników o mocy poniżej 25 KM, środowisk nadmorskich/wilgotnych oraz zastosowań, w których waga ma znaczenie (kosiarki wykańczające, małe kosiarki obrotowe). Doskonałe odprowadzanie ciepła i odporność na korozję.
Lane żelazo: Wymagane do zastosowań o średniej i dużej mocy powyżej 25 KM. Doskonała odporność na wstrząsy i sztywność konstrukcyjna do koszenia krzewów, intensywnego koszenia, uprawy roli i kopania dołków.
🔧 Standardowa a niestandardowa skrzynia biegów

🛠 Przewodnik instalacji i konfiguracji
Follow these steps to install the EP-30 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 EP-30 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.
❓ Najczęściej zadawane pytania
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.
What gear oil does this cultivator gearbox require?
Use SAE 90 or GL-5 rated EP90 heavy-duty gear oil. The high-torque tilling application demands extreme-pressure additives to protect the gear teeth. Fill to the level plug — approximately 1.5 to 2.5 liters depending on model.
How do I know which column length to order?
Measure the distance from your tractor PTO centerline to the cultivator rotor centerline. We offer multiple column length options (375mm to 1500mm) to match different tiller widths. Contact us with your tiller model for a recommendation.
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.
