🔧 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

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

Pourquoi c'est important : Associé à la vitesse de la prise de force, cela définit le rapport de transmission exact dont votre boîte de vitesses a besoin.

Step 2: Operating Environment

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

Pourquoi c'est important : Détermine le degré d'étanchéité approprié, le revêtement de surface et les spécifications du matériau du boîtier

Step 3: Working Hours per Season

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

Pourquoi c'est important : Les opérations à forte cadence justifient des spécifications haut de gamme pour les roulements et les engrenages afin d'obtenir le coût horaire le plus bas.

Step 4: Rotation Direction

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

Pourquoi c'est important : Un sens de rotation incorrect endommagera l'outil ou ne produira aucun travail utile.

Step 5: Mounting Bolt Pattern

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

Pourquoi c'est important : Permet une installation directe par boulonnage, sans aucune fabrication ni plaque d'adaptation.

Step 6: Torque Demand

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

Pourquoi c'est important : La boîte de vitesses doit supporter le couple maximal sans déclencher la protection contre les surcharges en fonctionnement normal.

Step 7: Output Shaft Type

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

Pourquoi c'est important : 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

Retirez le bouchon de remplissage et ajoutez lentement l'huile de boîte de vitesses recommandée jusqu'au repère de niveau. Utilisez la viscosité spécifiée dans la documentation de la boîte (généralement SAE 80W-90 GL-5 ou équivalent). Remettez le bouchon de remplissage en place et serrez-le à la main, puis à l'aide d'une clé. Vérifiez que le bouchon de mise à l'air libre est propre et dégagé.

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

Repérez le bouchon de vidange de la boîte de vitesses existante et placez un récipient de récupération en dessous. Retirez le bouchon et laissez l'huile s'écouler complètement. Examinez l'huile afin de détecter la présence de particules métalliques ou une décoloration pouvant indiquer une usure interne. Notez la référence de l'ancienne boîte de vitesses, le diamètre des boulons de fixation et les dimensions de l'arbre pour référence.

⚠ Important : 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.

⚠ Bruit de grincement ou de sifflement anormal

Cause probable : Lubrifiant insuffisant ou huile de qualité inadéquate

Action recommandée : Vidangez l'huile et vérifiez l'absence de particules métalliques. Remplissez-la avec l'huile de la viscosité appropriée. Si le bruit persiste après la vidange, une inspection des roulements ou des engrenages est nécessaire. Contactez l'assistance technique pour obtenir des instructions de réfection.

⚠ Fuite d'huile au niveau des joints d'arbre

Cause probable : Un niveau d'huile trop élevé crée une pression interne excessive.

Action recommandée : Vérifiez et corrigez d'abord le niveau d'huile : un excès d'huile est une cause étonnamment fréquente de fuites au niveau du joint. Nettoyez ou remplacez le bouchon de reniflard. Si le niveau d'huile est correct et que le reniflard est dégagé, le joint est usé et doit être remplacé à l'aide de notre kit de joints.

⚠ Output Shaft Stops Turning While Input Rotates

Cause probable : Stripped gear teeth or broken gear

Action recommandée : 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.

⚠ Vibrations excessives pendant le fonctionnement

Cause probable : Joints de cardan usés dans la transmission

Action recommandée : 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.

⚠ La boîte de vitesses produit un claquement métallique lors de l'engagement de la prise de force.

Cause probable : composants internes desserrés ou quincaillerie de fixation

Action recommandée : Un claquement lors de l'engagement de la prise de force (mais pas en fonctionnement) indique généralement un jeu dans la transmission ; vérifiez l'usure du tube télescopique. Si le claquement se produit en fonctionnement, il peut indiquer un jeu excessif des engrenages dû à l'usure interne. Si le bruit s'aggrave, faites inspecter la boîte de vitesses.

Si un problème quelconque ne peut être résolu par les actions ci-dessus, contactez notre équipe d'assistance technique Pour un diagnostic expert, nous pouvons organiser un dépannage à distance ou expédier une unité de remplacement en cas de panne critique.
