Gearbox for Combined Tillage

High-Performance Agricultural Gearbox for Combined Tillage Applications

Productive multi-function tillage starts with dependable power transmission. The Combined Tillage gearbox we manufacture is a precision instrument — not a commodity part. The combined tillage gearbox is a multi-output unit that simultaneously drives discs, tines, and packer rollers from a single PTO input. Positioned centrally on the implement frame, it distributes power to each working element through separate gear trains.

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.

🔧 Inside the Combined Tillage Gearbox — Engineering Principles

The gearbox in your combined tillage machine is a precision power conversion device. Let us trace the energy pathway:

Input: Capturing PTO Energy

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 spherical roller bearings selected specifically for the load profile of multi-function tillage applications.

Transformation: The Gear Train

Inside the housing, precisely meshed straight bevel gears convert PTO high-speed input into modified speed and amplified torque for the multi-shaft output. The combined tillage gearbox is a multi-output unit that simultaneously drives discs, tines, and packer rollers from a single PTO input. Positioned centrally on the implement frame, it distributes power to each working element through separate gear trains. Gear tooth profiles are case-hardened to HRC 58-62 and precision-ground, achieving 96-98% mechanical efficiency.

Output: Driving the Multi-Shaft Output

The gearbox output shaft connects directly to the combined tillage machine’s multi-shaft output, delivering torque-multiplied power for productive multi-function tillage. The output coupling is machined to precise tolerances for responsive, zero-backlash power delivery.

Protection: Sealing & Lubrication

A multi-layer protection system extends service life: grey cast iron housing resists impact and corrosion, VITON FKM lip seals block contaminants, mineral 85W-90 GL-4 maintains hydrodynamic film on all surfaces, and a breather vent equalizes pressure during temperature changes.

🎯 Combined Tillage Gearbox Sizing Guide — Get the Right Fit First Time

Use this step-by-step guide to identify the exact gearbox model for your combined tillage machine. Click each step for detailed instructions.

Step 1: Required multi-shaft output Speed

How: Refer to your combined tillage machine manufacturer’s manual for the recommended multi-shaft output operating speed

Why it matters: Together with PTO speed, this defines the exact gear ratio your gearbox needs

Step 2: Operating Environment

How: Assess exposure to dust, moisture, chemicals, and temperature extremes in your typical multi-function tillage conditions

Why it matters: Determines the appropriate seal grade, surface coating, and housing material specification

Step 3: Working Hours per Season

How: Estimate your annual operating hours for the combined tillage machine to determine appropriate service life rating

Why it matters: High-hour operations justify premium bearing and gear specifications for lowest cost per hour

Step 4: Rotation Direction

How: Determine whether the multi-shaft output on your combined tillage machine requires clockwise or counter-clockwise output when viewed from the drive end

Why it matters: Incorrect rotation direction will damage the implement or produce no useful work

Step 5: Mounting Bolt Pattern

How: Measure the bolt hole positions, centre distances, and overall envelope on your combined tillage machine’s gearbox mounting flange

Why it matters: Ensures direct bolt-on installation without any fabrication or adapter plates

Step 6: Torque Demand

How: Calculate the peak torque your multi-function tillage application generates — including shock loads from obstacles or material variations

Why it matters: The gearbox must handle peak torque without activating overload protection during normal operation

Step 7: Output Shaft Type

How: Identify the coupling type on your combined tillage machine — keyed, splined, flanged, or hollow bore

Why it matters: Mismatched outputs require costly adapter couplings and introduce potential failure points

🔧 Technician’s Installation Manual — Combined Tillage Gearbox

Follow these instructions for a successful installation of your new Combined Tillage gearbox. Correct installation is critical for achieving maximum service life and warranty coverage.

Step 1: 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 2: Position & Secure New Gearbox

Carefully lift the new Combined Tillage gearbox into position on the mounting flange, aligning all bolt holes. Insert mounting bolts hand-tight first, confirming proper alignment. Once all bolts are started, torque them in a star (cross) pattern to the value specified in the installation manual. Verify the gearbox sits flush against the frame with no gaps.

Step 3: 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 4: Connect Output to multi-shaft output

Attach the gearbox output shaft to the combined tillage machine’s multi-shaft output 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 5: 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.

Step 6: Prepare the Mounting Surface

Clean the mounting flange on the combined tillage machine 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 7: 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.

⚠ Ważne: Always consult the specific installation manual shipped with your Combined Tillage gearbox for model-specific torque values and procedures.

🔎 Diagnostic Checklist — Combined Tillage Gearbox

Use this diagnostic reference to identify and resolve common Combined Tillage gearbox issues in the field. Most problems can be diagnosed and addressed without removing the gearbox from the combined tillage machine.

⚠ Abnormal Grinding or Whining Noise

Probable Cause: Insufficient lubricant or incorrect oil grade

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.

⚠ Wyciek oleju z uszczelnień wału

Probable Cause: Overfilled oil level creating excess internal pressure

Recommended Action: First, check and correct the oil level — overfilling is a surprisingly common cause of seal leaks. Clean or replace the breather cap. If oil level is correct and breather is clear, the seal has worn and should be replaced using our seal kit.

⚠ Wał wyjściowy przestaje się obracać, podczas gdy wał wejściowy się obraca

Probable Cause: Stripped gear teeth or broken gear

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 internal damage and requires professional service.

⚠ Excessive Vibration During Operation

Probable Cause: Worn universal joints in the driveline

Recommended Action: First check all mounting bolt torques — vibration frequently loosens fasteners, which then amplifies the vibration. Next, inspect the PTO driveline U-joints for wear or binding. Verify driveline angles are within specification. Finally, check the output coupling to the multi-shaft output for wear or damage.

⚠ Skrzynia biegów wydaje metaliczny dźwięk stukania podczas włączania WOM

Probable Cause: Loose internal components or retaining hardware

Recommended Action: A clunking sound specifically on PTO engagement (but not during operation) usually indicates driveline lash — check driveline telescoping tube for wear. If the clunk occurs during operation, it may indicate excessive gear backlash from internal wear. Have the gearbox inspected if the sound is progressive.

If any issue cannot be resolved with the actions above, contact our technical support team for expert diagnosis. We can arrange remote troubleshooting or dispatch a replacement unit for critical breakdown situations.
