High-Performance Agricultural Gearbox for Disc Mower Applications
Productive hay cutting starts with dependable power transmission. The Disc Mower gearbox we manufacture is a precision instrument — not a commodity part. The disc mower gearbox sits within the cutter bar, driving a series of spinning discs via an internal gear train. Each disc rotates at high speed (approximately 3,000 RPM), and the gearbox distributes PTO power evenly across all discs to ensure a uniform cut.
From the hardened gear teeth to the heavy-duty shaft seals, every element is selected and assembled to deliver thousands of hours of trouble-free service. Australian farmers operating in dust, heat, mud, and moisture rely on this gearbox to perform consistently throughout the most demanding seasons.

🔧 Power Pathway: How Your Disc Mower Gearbox Works
Let us examine how the gearbox in a disc mower operates:
| Subsystem |
Function |
| PTO Input |
Power enters through a precision-machined splined coupling accepting 540 RPM (1-3/8″) or 1000 RPM (1-3/4″) PTO output. The input shaft rides on double-row tapered roller bearings selected specifically for the load profile of hay cutting applications. |
| Gear Reduction |
Precision planetary gears inside the gearbox reduce PTO speed while multiplying torque to match the disc drive train’s demands. The disc mower gearbox sits within the cutter bar, driving a series of spinning discs via an internal gear train. Each disc rotates at high speed (approximately 3,000 RPM), and the gearbox distributes PTO power evenly across all discs to ensure a uniform cut. The gears are manufactured from carburized alloy steel, ground to tight tolerances, and profiled for quiet, efficient power transfer. |
| Output Drive |
The transformed power exits through the output shaft to the disc mower’s working mechanism, specifically driving the disc drive train for core hay cutting function. The output connection is engineered for vibration-free, backlash-free transmission at the point of work. |
| Sealing & Lubrication |
Every shaft penetration is protected by a VITON FKM lip seal, creating multi-barrier defense against dust, moisture, and crop debris. mineral 85W-90 GL-4 provides continuous splash lubrication. The cast iron housing features integrated cooling fins for thermal management. |

🔧 Technician’s Installation Manual — Disc Mower Gearbox
Follow these instructions for a successful installation of your new Disc Mower gearbox. Correct installation is critical for achieving maximum service life and warranty coverage.
Step 1: Remove Old Gearbox
Disconnect the PTO driveline from the gearbox input shaft. Support the gearbox weight with a floor jack or overhead hoist (typical weight: 15-70 kg depending on model). Remove all mounting bolts in a criss-cross pattern to relieve clamping stress evenly. Carefully lower the old gearbox and set it aside.
Step 2: Drain & Document Old Gearbox
Locate the drain plug on the existing gearbox and position a catch container underneath. Remove the drain plug and allow all oil to drain completely — inspect the oil for metal particles or discolouration that may indicate internal wear. Record the old gearbox model number, mounting bolt size, and shaft dimensions for reference.
Step 3: Connect Output to disc drive train
Attach the gearbox output shaft to the disc mower’s disc drive train drive coupling. For keyed connections, align the keyway and slide the coupling on, then secure with the retaining bolt and torque to specification. For splined outputs, apply anti-seize to the splines and verify full engagement before locking.
Step 4: Prepare the Mounting Surface
Clean the mounting flange on the disc mower frame with a wire brush and solvent, removing all old sealant, rust, and debris. Inspect the mounting surface for cracks, stripped threads, or warping. Chase any damaged bolt threads with a tap. Apply a thin film of anti-seize compound to the mounting face if specified.
Step 5: Fill With Lubricant
Remove the fill plug and slowly add the recommended gear oil until it reaches the level indicator. Use the lubricant grade specified in the gearbox documentation (typically SAE 80W-90 GL-5 or equivalent). Replace the fill plug and hand-tighten, then snug with a wrench. Verify the breather cap is clean and unobstructed.
Step 6: Connect PTO Driveline
Align the PTO driveline with the gearbox input shaft and slide the yoke onto the splines until the locking mechanism engages. Verify the spline count matches (6-spline for 540 RPM, 21-spline for 1000 RPM). Check that driveline operating angles do not exceed 15° — excessive angles cause premature U-joint failure and vibration.
Step 7: Safety Preparation
Park the tractor on firm, level ground. Engage the parking brake and place wheel chocks. Turn off the engine and remove the key. Disconnect the PTO shaft from the disc mower. Allow all components to cool completely before touching. Wear appropriate PPE including gloves and safety glasses.
Step 8: Test Run & Break-In
Start the tractor and engage the PTO at low RPM (approximately 300 RPM). Listen carefully for any grinding, whining, knocking, or clicking sounds. Run at low speed for 15-20 minutes, monitoring the gearbox housing temperature by hand (carefully). Check for oil leaks at all seals and the mounting interface. Gradually increase to full operating speed.
⚠ Quan trọng: Always consult the specific installation manual shipped with your Disc Mower gearbox for model-specific torque values and procedures.

⚠ Tiếng mài hoặc tiếng rít bất thường
Probable Cause: Thiếu chất bôi trơn hoặc sử dụng loại dầu không phù hợp.
Recommended Action: Drain and inspect oil for metal particles. Refill with correct grade. If noise persists after oil change, bearing or gear inspection is required. Contact support for rebuild guidance.
⚠ Hộp số hoạt động quá nóng
Probable Cause: Operating beyond rated horsepower or duty cycle
Recommended Action: Check oil level and grade against the specification. Clean all debris from the housing exterior — especially the cooling fins. If the disc mower is being operated at or above the gearbox’s rated power, reduce forward speed or PTO load. Consider upgrading to synthetic gear oil for improved thermal performance.
⚠ Khó khăn khi kết nối trục truyền động PTO với hộp số
Probable Cause: Rust or debris on the input shaft splines
Recommended Action: Clean the input shaft splines with a wire brush and apply a light coat of anti-seize. Slowly rotate the PTO shaft while pushing to align the splines. If the splines will not engage, verify the spline count matches your PTO standard — 6-spline for 540 RPM, 21-spline for 1000 RPM.
⚠ Trục đầu ra ngừng quay trong khi trục đầu vào quay
Probable Cause: Răng bánh răng bị mòn hoặc bánh răng bị hỏng
Recommended Action: Check the overload protection device first — this is the most likely cause if the gearbox was recently subjected to a sudden overload. Replace the shear bolt or reset the slip clutch per the manual. If overload protection is intact, the gearbox has
