High-Performance Agricultural Gearbox for Stone Burier Applications
Your stone burier depends on a gearbox that can translate raw PTO power into productive soil preparation force — reliably, efficiently, and without unexpected failure. That is exactly what our Stone Burier agricultural gearbox delivers. Mounted centrally on the stone burier frame, this gearbox powers the rotor that lifts soil and rocks, sifts them through a rear screen, and buries stones below the surface while leaving a smooth, stone-free seedbed on top.
We engineer each gearbox specifically for the mechanical profile of soil preparation. The gear geometry, bearing selection, and housing design are all optimized for the load patterns, duty cycles, and environmental exposures unique to stone burier operations across Australian farming conditions.

⚙ From PTO to Screening Rotor — Stone Burier Gearbox Anatomy
De Stone Burier gearbox operation can be understood through four interconnected systems:
1 — Input System: Your tractor’s PTO shaft engages with the gearbox through a hardened splined input shaft. The interface transmits torque while allowing minor angular misalignment. Inside, spherical roller bearings support the input shaft and manage the combined loading of transmitted torque and driveline forces.
2 — Conversion System: Precision crown gears inside the gearbox reduce PTO speed while multiplying torque to match the screening rotor’s demands. Mounted centrally on the stone burier frame, this gearbox powers the rotor that lifts soil and rocks, sifts them through a rear screen, and buries stones below the surface while leaving a smooth, stone-free seedbed on top. The gears are manufactured from carburized alloy steel, ground to tight tolerances, and profiled for quiet, efficient power transfer.
3 — Output System: The transformed power exits through the output shaft to the stone burier’s working mechanism, specifically driving the screening rotor for core soil preparation function. The output connection is engineered for vibration-free, backlash-free transmission at the point of work.
4 — Protection System: Every shaft penetration is protected by a labyrinth seal, creating multi-barrier defense against dust, moisture, and crop debris. synthetic PAO 75W-90 provides continuous splash lubrication. The grey cast iron housing features integrated cooling fins for thermal management.

🛠 Installation Procedure for Your Stone Burier Gearbox
This guide covers the complete process of replacing the gearbox on your stone burier. Each step includes specific details for soil preparation equipment — follow them in sequence for best results.
Step 1 — Connect Output to screening rotor
Connect the output coupling to the screening rotor drive on your stone burier. Ensure the shaft engagement depth meets the minimum specified in the manual. Tighten all retaining hardware to the correct torque value. After connection, rotate the output by hand to verify smooth, unrestricted movement.
Step 2 — Post-Installation Checks (10-Hour Service)
Voer een 10-uurs onderhoudsbeurt uit: controleer het aanhaalmoment van de bevestigingsbouten opnieuw, inspecteer op lekkages, controleer het oliepeil en bevestig dat de aftakasbeveiliging op zijn plaats zit. Verwijder eventueel opgehoopt vuil uit de versnellingsbakbehuizing om een effectieve warmteafvoer te garanderen. Noteer de installatiegegevens in uw onderhoudslogboek.
Stap 3 — Vullen met smeermiddel
Vul de versnellingsbakolie bij via de vulopening. Gebruik de oliesoort die in de installatiehandleiding wordt aanbevolen. Vul bij tot er net olie uit het niveaucontrolegaatje (indien aanwezig) begint te sijpelen of tot het de bodem van de vulopening bereikt. Veeg gemorste olie van de behuizing. Controleer of de magnetische aftapplug volledig vastzit.
Step 4 — Remove Old Gearbox
Detach the driveline yoke from the gearbox input. If the gearbox also has an output coupling to the screening rotor, disconnect that as well. Support the gearbox from below with a hydraulic jack. Remove the mounting fasteners progressively, keeping at least two bolts finger-tight until you are ready to slide the unit out.
Stap 5 — Testrun & Inloop
With the stone burier raised or in a safe test position, start the PTO at idle speed. Observe the gearbox for any vibration, unusual noise, or oil seepage. Run for 20 minutes at reduced speed. If all is normal, increase to the operating PTO speed and run for an additional 10 minutes while monitoring temperature. Re-check all mountings.
Step 6 — Connect PTO Driveline
Schuif de aftakas-aandrijfasflens over de ingaande as van de versnellingsbak. Zorg voor volledige aangrijping: de flens moet langs de borggroef schuiven en vastklikken. Test de aangrijping door stevig aan de flens te trekken; deze mag niet loskomen. Controleer of de lengte van de aandrijfas voldoende telescopische slag mogelijk maakt over het volledige bewegingsbereik van het werktuig.
Step 7 — Prepare the Mounting Surface
Scrape any old gasket material or RTV sealant from the stone burier’s gearbox mounting face. Use a flat file to remove any burrs around bolt holes. Verify all mounting holes align correctly by test-fitting the new gearbox without bolts. Check for flatness — a feeler gauge should show less than 0.1mm across the mounting surface.
⚠ Belangrijk: Werk voor uw eigen veiligheid nooit onder onondersteunde apparatuur. Gebruik geschikte hijsinstallaties bij het hanteren van de versnellingsbak.
⚠ Fault Diagnosis Guide — Stone Burier Gearbox
Even the best-engineered gearbox may encounter operational issues over its service life. This guide covers the most common symptoms reported with stone burier gearboxes and provides actionable field solutions.
⚠ Olielekkage bij asafdichtingen
Waarschijnlijke oorzaak: Overfilled oil level creating excess internal pressure
Wat te doen: Controleer de ontluchtingsdop — een verstopte ontluchtingsdop zet de behuizing onder druk en perst olie langs de afdichtingen. Vervang de ontluchtingsdop en verwijder eventueel vuil. Als de lekkage aanhoudt, vervang dan de betreffende afdichting. Controleer het asoppervlak onder de afdichting op groeven of corrosie die de afdichtingslip kunnen beschadigen.
⚠ Overmatige trillingen tijdens gebruik
Waarschijnlijke oorzaak: Worn universal joints in the driveline
Wat te doen: Vibration in a stone burier gearbox system usually originates from the driveline, not the gearbox itself. Inspect the PTO shaft U-joints — a worn joint creates a twice-per-revolution vibration pulse. Confirm the driveline is the correct length for the tractor-to-implement distance. Re-torque the gearbox mounting bolts.
⚠ Abnormaal schurend of piepend geluid
Waarschijnlijke oorzaak: Insufficient lubricant or incorrect oil grade
Wat te doen: Check oil level immediately — low oil is the most common cause of gear noise in stone burier gearboxes. If oil level is correct, the lubricant may have degraded — perform a complete oil change. Persistent noise indicates internal wear requiring professional assessment.
⚠ Gearbox Running Excessively Hot
Waarschijnlijke oorzaak: Operating beyond rated horsepower or duty cycle
Wat te doen: Measure housing temperature (normal operating range: 40-80°C depending on ambient temperature). If consistently above 90°C, verify oil volume, clean the housing, and check that the gear ratio produces the correct output speed. An incorrect ratio forces the gearbox to work harder, generating excess heat.
⚠ De uitgaande as stopt met draaien terwijl de ingaande as draait
Waarschijnlijke oorzaak: Stripped gear teeth or broken gear
Wat te doen: Als de versnellingsbak een breekpen of slipkoppeling heeft, controleer dan of deze geactiveerd is. Een geactiveerde overbelastingsbeveiliging is een beveiligingsmaatregel, geen defect. Vervang de breekpen en onderzoek de oorzaak van de overbelasting. Als de overbelastingsbeveiliging intact is, maar er geen vermogen wordt geleverd, is er sprake van een defect aan een intern tandwiel of een as.
