Industrial-Strength Power Harrow Gearbox — Reliable Power for Soil Cultivation
When soil cultivation efficiency is your priority, the gearbox connecting your tractor to the power harrow becomes the most critical component on the implement. Our agricultural gearbox for Power Harrow applications uses advanced gear technology to maximize power transfer while minimizing heat generation and mechanical wear. The power harrow gearbox distributes PTO torque across multiple vertical tine shafts via an internal gear train. Bolted to the harrow’s main beam, it ensures each set of tines counter-rotates to crumble clods without inverting the soil profile.
Backed by rigorous quality control and bench-tested before shipment, every unit meets the exacting standards demanded by professional Australian farmers who cannot afford mid-season breakdowns.

📝 Step-by-Step: How to Select Your Power Harrow Gearbox
Before ordering your Power Harrow gearbox, confirm these critical parameters to ensure perfect fitment and performance:
Working Hours per Season
Estimate your annual operating hours for the power harrow to determine appropriate service life rating
High-hour operations justify premium bearing and gear specifications for lowest cost per hour
Torque Demand
Calculate the peak torque your soil cultivation application generates — including shock loads from obstacles or material variations
La caja de cambios debe soportar el par máximo sin activar la protección contra sobrecarga durante el funcionamiento normal.
Mounting Bolt Pattern
Measure the bolt hole positions, centre distances, and overall envelope on your power harrow’s gearbox mounting flange
Garantiza una instalación directa mediante pernos sin necesidad de modificaciones ni placas adaptadoras.
Operating Environment
Assess exposure to dust, moisture, chemicals, and temperature extremes in your typical soil cultivation conditions
Determina el grado de sellado, el recubrimiento de la superficie y las especificaciones del material de la carcasa adecuados.
Tipo de eje de salida
Identify the coupling type on your power harrow — keyed, splined, flanged, or hollow bore
Las salidas incompatibles requieren costosos acoplamientos adaptadores e introducen posibles puntos de fallo.
Dirección de rotación
Determine whether the tine drive on your power harrow requires clockwise or counter-clockwise output when viewed from the drive end
Una dirección de rotación incorrecta dañará el implemento o no producirá ningún trabajo útil.
Power Requirement
Match the gearbox HP rating to your tractor’s PTO horsepower output and the power harrow’s demand
Under-rating leads to overheating and premature failure; over-rating adds unnecessary cost and weight

⚙ Fitting Guide: Power Harrow Gearbox on Your power harrow
Installing a new gearbox on your harrowing implement is a straightforward process when done methodically. Allow approximately 1-2 hours for a complete replacement using standard hand tools.
Separate the PTO driveline and the output connection to the tine drive. Mark the orientation of the gearbox on the frame before removal. Use an appropriate lifting device (the gearbox may be heavier than it looks). Remove mounting bolts working from the outside in, then gently pull the gearbox away from the mounting surface.
Apply a thin coat of lithium grease to the input shaft splines. Engage the PTO driveline, confirming the splines mesh fully and the safety collar locks into position. Check the driveline angles: measure with an inclinometer if possible. Angles above 15° require a CV (constant velocity) joint upgrade to prevent vibration damage.
Perform an initial low-speed test: engage PTO at half speed for 10 minutes, stop, check for leaks and abnormal heat. If clear, run at full speed for 20 minutes under light load. After the initial test, perform a short field trial under actual soil cultivation conditions at reduced forward speed. Monitor gearbox temperature and sound throughout.
Mate the gearbox output to the tine drive input. If using a flanged connection, align the bolt holes and use grade 8.8 or higher fasteners torqued to specification. If keyed or splined, confirm the coupling seats fully before applying locking hardware. Verify zero binding by hand-rotating the assembly.
Complete a first-service at 10 operating hours: retorque all fasteners, change the break-in oil and replace with fresh oil of the specified grade, inspect seals and breather, and confirm the tine drive connection remains tight. This early service removes any metallic particles generated during initial gear run-in.
Ensure the power harrow is fully supported and cannot roll or tip. Shut down the tractor, remove the key, and disconnect the battery if working near electrical components. Lower all hydraulic implements to the ground. Put on safety gloves, steel-cap boots, and eye protection before beginning any work.
Thoroughly clean the harrowing implement’s gearbox mating surface. Remove all rust, paint, and sealant residue. Inspect the mounting face for any damage — dents, cracks, or corrosion that could prevent a flush fit. If mounting studs are used, verify they are tight and undamaged.

📚 Power Harrow Gearbox — Your Questions Answered
Can I return a gearbox if it does not fit my power harrow?
Si nos facilita los detalles de su equipo antes de realizar el pedido y confirmamos la compatibilidad, le garantizamos que encajará perfectamente. En el improbable caso de que surja algún problema de compatibilidad, le ofrecemos un cambio o reembolso sin preguntas para las cajas de cambios sin usar dentro de los 30 días posteriores a la entrega. Nuestro objetivo es que reciba la caja de cambios correcta en su primer pedido.
Can the output shaft be customized for my specific power harrow?
Absolutely. We manufacture gearboxes with keyed, splined, flanged, hex, and hollow-bore output shaft configurations. If your power harrow requires a non-standard output size, spline count, or connection type, our engineering team will design and machine it to your exact specifications at no additional lead time for common modifications.
¿Cómo puedo determinar el modelo de caja de cambios correcto para mi equipo?
Provide us with your tractor brand/model and PTO speed, the power harrow manufacturer and model, and the old gearbox part number if available. Alternatively, measure the input/output shaft dimensions and mounting bolt pattern. Our selection engineers will identify the correct match, typically within 24 hours.
Can the gearbox be serviced or rebuilt in the field?
Routine service (oil changes, seal replacement, bearing inspection) can be performed on-site with standard tools. For major rebuilds, we supply complete overhaul kits containing all bearings, seals, and gaskets. Detailed service manuals and video guides are available for download from our support portal.
¿Qué aceite para engranajes recomienda para las condiciones australianas?
Para la mayoría de los climas australianos, el aceite para engranajes SAE 80W-90 EP con especificación GL-5 es ideal. En regiones tropicales con temperaturas elevadas sostenidas, recomendamos 85W-140. Para las regiones del sur con inviernos fríos, el aceite sintético 75W-90 ofrece una mejor protección en el arranque en frío. Consulte la ficha técnica del aceite que se incluye con su caja de cambios para obtener la recomendación definitiva.
Do you provide technical support after purchase?
