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
The 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)
Perform a 10-hour service: re-check mounting bolt torque, inspect for leaks, verify oil level, and confirm the PTO safety guard is in place. Clean any accumulated debris from the gearbox housing to maintain effective heat dissipation. Log the installation details in your equipment maintenance records.
Step 3 — Fill With Lubricant
Add gear oil through the fill port. Use the grade recommended in the installation manual. Fill until oil just begins to weep from the level check hole (if provided) or reaches the bottom of the fill port. Wipe any spilled oil from the housing. Confirm the magnetic drain plug is fully seated.
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.
Step 5 — Test Run & Break-In
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
Slide the PTO driveline yoke over the gearbox input spline. Ensure full engagement — the yoke should slide past the retaining groove and click into place. Test the engagement by pulling firmly on the yoke; it should not detach. Verify that the driveline length allows adequate telescoping stroke throughout the full range of implement movement.
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.
⚠ Маңызды: For safety, never work under unsupported equipment. Use proper lifting devices when handling the gearbox unit.
⚠ 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.
⚠ Білік тығыздағыштарынан майдың ағуы
Likely cause: Майдың шамадан тыс толтырылуы ішкі қысымның жоғарылауына әкеледі
What to do: Inspect the breather cap — a blocked breather pressurizes the housing and forces oil past seals. Replace the breather and clean any debris. If leaking continues, replace the affected seal. Check the shaft surface under the seal for grooves or corrosion that may be cutting the seal lip.
⚠ Жұмыс кезінде шамадан тыс діріл
Likely cause: Қозғалтқыш жолындағы тозған әмбебап қосылыстар
What to do: 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.
⚠ Қалыптан тыс сықырлау немесе ыңылдау шуылы
Likely cause: Майлау материалы жеткіліксіз немесе майдың дұрыс емес деңгейі
What to do: 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
Likely cause: Operating beyond rated horsepower or duty cycle
What to do: 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.
⚠ Кіріс айналған кезде шығыс білігі айналуын тоқтатады
Likely cause: Тісті доңғалақтың жұлынған тістері немесе сынған берілісі
What to do: If the gearbox has a shear pin or slip clutch, inspect it for activation. A tripped overload device is a protective event, not a failure — replace the pin and investigate what caused the overload. If the overload device is intact but no output is produced, internal gear or shaft failure has occurred.
