How a PTO Shaft Works on a Hayrake
The PTO shaft transmits rotational energy from the tractor’s rear PTO stub to the input shaft of the hayrake. The assembly consists of two yokes connected by a telescoping profile tube, with universal joints (U-joints) at each end allowing angular misalignment as the tractor and implement articulate over uneven ground.
During hay windrow formation, the tractor PTO stub rotates at a standardised speed. This rotation passes through the first U-joint, travels along the profile tube (which telescopes to accommodate changes in distance), and exits through the second U-joint into the implement gearbox. A safety guard encloses the entire rotating assembly to prevent entanglement.
On the hayrake specifically, the PTO shaft drives the main gearbox, which in turn powers the working elements. Overload protection—typically a shear bolt or friction clutch—is integrated at the implement-end yoke to safeguard the driveline against sudden blockages or shock loads.
Core Advantages of Our PTO Shaft for Hayrake
⚙ Heat-Treated Components
Every yoke and U-joint cross in our hayrake PTO shaft is induction-hardened and tempered, delivering superior fatigue resistance compared to standard cast components.
⚖ Precision-Balanced Assembly
Computer-balanced shaft assemblies minimise vibration, reducing wear on tractor and implement bearings and extending overall driveline life.
🔒 Integrated Overload Protection
Factory-fitted torque limiters protect your investment by automatically disengaging under shock loads, preventing costly repairs to gearboxes and drivelines.
🔧 Telescoping Design
Profile tubes telescope smoothly to accommodate field undulations and turning manoeuvres, ensuring consistent power delivery during operation.
🛡 Full Safety Guarding
CE-compliant safety shields with bearing-mounted rotation enclose the entire shaft, meeting Australian WHS requirements and protecting operators.

Targeted Installation Procedure – Hayrake PTO Shaft
⚠ Safety First: Disengage the PTO, switch off the engine, remove the ignition key, and allow all moving parts to come to a complete stop before working on the driveline. Wear appropriate PPE including close-fitting clothing and gloves.
Phase 1: Preparation
Lay out all shaft components and cross-reference against the packing list. Confirm the shaft series, closed length, and yoke specifications match your hayrake setup. Grease all U-joint nipples and slide the profile tubes back and forth several times to distribute lubricant.
Phase 2: Length Verification
With the hayrake hitched to the tractor in its normal operating position, measure the PTO-to-input distance. The shaft must have a minimum of 1/3 tube overlap at full extension and must not bottom out at the shortest position. Trim the tubes if the factory length requires adjustment (refer to cutting instructions in the product manual).
Phase 3: Tractor Connection
Push the tractor-end yoke fully onto the PTO stub. The quick-release collar should snap over the retaining groove. Pull back on the yoke to confirm it is locked. If using a plain-bore yoke, insert the shear pin and secure with a cotter pin.
Phase 4: Implement Connection
Connect the implement-end yoke to the hayrake’s input. If a clutch assembly is fitted at this end, ensure the clutch housing is oriented with the grease nipple accessible. Tighten any set screws to the specified torque.
Phase 5: Guard Fitting
Assemble the two guard halves around the shaft and clip together. Attach the anti-rotation chains: one chain to a stationary tractor point, one chain to the implement frame. Verify the guards spin freely by hand without contacting any part of the shaft or yokes.
Phase 6: Operational Test
Start the tractor, engage PTO at low idle, and run the hayrake unloaded for two to three minutes. Check for vibration, abnormal noise, or heat at the U-joints. If all checks pass, proceed to normal operating speed and begin field work. Re-torque all fasteners after the initial run-in period.
PTO Shaft Troubleshooting Guide for Hayrake
⚠ Clicking or knocking noise at low speed
Possible Cause: Bantalan jarum sambungan U aus; dudukan longgar pada poros PTO
Recommended Action: Ganti rakitan sambungan U; periksa keausan spline dan mekanisme penguncian yoke.
⚠ Shaft will not telescope smoothly
Possible Cause: Korosi atau kotoran di dalam tabung profil; pelumasan yang tidak memadai.
Recommended Action: Bersihkan dan lumasi tabung profil; ganti jika terlihat goresan.
⚠ Safety guard not rotating freely
Possible Cause: Bantalan pelindung macet; pelindung rusak atau tidak sejajar
Recommended Action: Ganti bantalan pelindung; luruskan atau ganti bagian pelindung; pasang kembali rantai dengan benar.
⚠ Unusual whining or grinding sound
Possible Cause: Kerusakan bantalan input gearbox; poros tidak sejajar
Recommended Action: Periksa kotak roda gigi alat pertanian; sejajarkan kembali traktor dan alat pertanian; periksa tumpang tindih panjang poros.
⚠ Excessive vibration during operation
Possible Cause: Worn U-joint cross bearings; shaft out of balance; excessive operating angle
Recommended Action: Replace U-joint cross kit; check yoke alignment; reduce operating angle to <25°

Frequently Asked Questions – PTO Shaft for Hayrake
❓ Bagaimana cara mengukur panjang tertutup yang tepat?
Pasang alat pertanian ke traktor pada posisi kerja normalnya. Ukur jarak garis lurus dari permukaan poros PTO traktor ke permukaan poros input alat pertanian. Panjang poros saat tertutup harus sekitar 10–15 mm lebih pendek dari pengukuran ini.
❓ Can the shaft be shortened to fit my setup?
Yes. The telescoping profile tubes can be cut to a shorter length using an angle grinder or chop saw. Ensure a minimum of 1/3 overlap remains between the inner and outer tubes after cutting. Deburr all cut edges before reassembly.
❓ Apakah poros PTO Anda seimbang?
Ya. Semua rakitan poros PTO kami diseimbangkan secara dinamis selama proses pembuatan. Hal ini mengurangi getaran, memperpanjang umur bantalan, dan memberikan pengoperasian yang lebih halus dibandingkan dengan alternatif aftermarket yang tidak seimbang.
❓ Seberapa sering saya harus melumasi poros PTO?
Lumasi semua nipel sambungan U setiap 8–10 jam pengoperasian, atau di awal setiap hari kerja. Lumasi tabung profil teleskopik pada interval yang sama. Gunakan gemuk kompleks litium EP2 atau seperti yang direkomendasikan dalam manual produk Anda.
❓ What PTO shaft series do I need for my hayrake?
For most hayrake applications in the 15–50 HP range, we recommend the T1 / L1 (Light duty) or T2 / L2 (Light-medium duty) series. If you operate near the upper end of this range or in particularly demanding conditions, consider stepping up to the G1 (Compact) series for additional safety margin.
❓ Will this shaft fit my tractor and hayrake?
Our PTO shafts are available with all standard yoke types and spline sizes (1-3/8" 6-spline, 1-3/4" 6-spline, 1-3/4" 20-spline, and more). Provide your tractor model and hayrake make/model, and our team will confirm compatibility before dispatch.
❓ Apa perbedaan antara baut geser dan kopling gesek?
Baut geser adalah pin pengorbanan yang patah ketika torsi melebihi kapasitas nominalnya. Harganya murah tetapi memerlukan penggantian manual setelah setiap kejadian. Kopling gesek selip ketika kelebihan beban dan secara otomatis terhubung kembali ketika kelebihan beban hilang, menawarkan pengoperasian tanpa gangguan dalam aplikasi yang rentan terhadap beban kejut yang sering terjadi.
❓ Can I upgrade my existing hayrake PTO shaft to a heavier series?
Dalam kebanyakan kasus, ya. Selama ukuran spline yoke sesuai dengan poros PTO traktor dan poros input implement Anda, Anda dapat melakukan upgrade ke seri yang lebih berat untuk meningkatkan kapasitas torsi dan daya tahan. Tim teknis kami dapat memberikan saran tentang jalur upgrade yang tepat untuk peralatan Anda.
