⭐ Główne cechy i zalety inżynieryjne
💧 Heavy-Duty Shaft Seals
Reinforced double-lip seals with integrated spring-loaded wipers prevent abrasive soil and mud from entering the gear chamber during vertical boring operations.
⚡ Maximum Torque Output
High reduction ratios (3:1 to 4:1) deliver sustained high-torque output at low speed — essential for augering through dense clay, shale, and root-filled ground without stalling.
🔧 Standard Auger Compatibility
Output shaft dimensions accommodate standard 2-inch hex and round auger bit connections used across major post hole digger and earth auger brands.
💥 Thrust Bearing Protection
Oversized angular contact thrust bearings absorb the significant axial loads generated during deep boring (up to 1.5m depth), protecting gear mesh alignment and extending service life.
🌡️ Field-Serviceable Design
Split housing construction with external drain and fill plugs allows lubricant changes and seal replacement in the field without removing the gearbox from the implement.
📈 Multiple Mounting Options
Compatible with both Category I and Category II three-point hitch post hole digger frames with standard bolt patterns.

🔎 Przewodnik po wyborze i rozmiarach
Post hole digger gearbox selection depends on boring depth, soil type, and tractor PTO output. Here is a structured approach to selecting the EP-GT40U:
⚙ 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-GT40U 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.

🛠 Przewodnik instalacji i konfiguracji
Follow these steps to install the EP-GT40U on your implement. Always refer to the included instruction manual for model-specific torque values and safety precautions.
- Attach the post hole digger frame to the tractor three-point hitch (Category I or II). Raise the frame and secure it in the vertical position.
- Remove the old gearbox by unbolting the top flange from the digger frame. Support the gearbox weight during removal — pit digger gearboxes can weigh 19-59 kg.
- Clean the frame mounting surface and inspect for cracks, worn bolt holes, or frame distortion.
- Lift the new EP-GT40U gearbox into position and align the mounting bolt holes with the digger frame. Install bolts and torque to the specified value (typically 60-90 Nm).
- Connect the PTO shaft to the gearbox input. Ensure the shear bolt is installed and spline engagement is complete.
- Attach the auger bit to the output shaft. Verify the retaining pin or bolt is secure and the auger rotates freely without wobble.
- Fill the gearbox with SAE 90 gear oil to the level plug. Lower the digger to the ground and run a test bore at low throttle to verify operation.
❓ Najczęściej zadawane pytania
What auger bit connection does the output shaft accept?
Standard output accepts 2-inch (50.8mm) round shaft auger bits. Some models also offer hex output shaft options. Confirm your auger bit connection type before ordering.
Can I bore into rocky soil with this gearbox?
Yes, within limits. Our pit digger gearboxes are designed for dense clay and moderate rock. For continuous boring in solid rock or heavily fractured stone, use our heavy-duty models (EP-01-084 or EP-2300058) rated at 50HP or above.
How deep can I dig with this gearbox?
Boring depth is limited by auger bit length, not the gearbox. Our gearboxes handle standard auger extensions for holes up to 1.5 meters deep in most soil types.
What causes the gearbox to stall during boring?
Common causes: hitting solid rock or large roots, insufficient tractor PTO horsepower, dull auger bit teeth, or operating in waterlogged ground. Reduce feed pressure, sharpen or replace auger teeth, and ensure tractor HP matches the gearbox rated power.
What oil and maintenance does a pit digger gearbox need?
Use SAE 90 or EP90 gear oil. Change after first 30 hours, then every 100 hours of boring operation. Inspect output shaft seal for soil ingress after every 20 boring hours and replace if worn.
