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.

⚙ 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?
ご注文前に機器の詳細をご提供いただき、弊社で互換性を確認させていただければ、適合は保証いたします。万が一、互換性の問題が発生した場合は、お届け後30日以内であれば、未使用のギアボックスを無条件で交換または返金いたします。弊社は、初回のご注文で最適なギアボックスをお届けすることを目指しております。
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.
How do I determine the correct gearbox model for my equipment?
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?
定期点検（オイル交換、シール交換、ベアリング点検）は、標準工具を使用して現場で実施できます。大規模なオーバーホールには、ベアリング、シール、ガスケットを含む完全なオーバーホールキットをご用意しています。詳細なサービスマニュアルとビデオガイドは、サポートポータルからダウンロードできます。
Which gear oil do you recommend for Australian conditions?
For most Australian climates, SAE 80W-90 EP gear oil meeting GL-5 specification is ideal. In tropical regions with sustained high temperatures, we recommend 85W-140. For southern regions experiencing cold winters, synthetic 75W-90 provides better cold-start protection. Check the oil specification card shipped with your gearbox for the definitive recommendation.
Do you provide technical support after purchase?
Yes — every purchase includes access to our engineering support team for installation guidance, troubleshooting, maintenance advice, and parts ordering. Support is available via phone, email, and our online contact form. There is no charge for technical support during or after the warranty period.
Will this gearbox fit older-model power harrow equipment?
We maintain compatibility databases covering power harrow models from the past 25+ years. Most older models can be directly fitted with our current gearbox range. For discontinued or rare models, send us the mounting dimensions and shaft specifications, and we will confirm fitment or design a custom adapter.
What payment and ordering options do you offer?
We accept bank transfer, credit card, and purchase orders from established accounts. For large orders, we offer 30-day payment terms subject to credit approval. Orders can be placed through our website, by email, or by phone. Pro-forma invoices are available for pre-payment arrangements.
What does the warranty cover and for how long?
Our 24-month comprehensive warranty covers all defects in materials and workmanship, including bearings, gears, seals, and housing. It applies from the date of purchase and is backed by our ISO-certified quality management system. Extended warranty programs are available for bulk and fleet orders.
What is the expected lifespan under continuous soil cultivation operation?
Our Power Harrow gearbox is rated for 3,000 to 5,000+ operating hours with proper maintenance. Many customers in intensive Australian operations report achieving 5,000+ hours before requiring any internal service. Key factors affecting lifespan include oil change frequency, operating load, and environmental conditions.
