Prinsip Kerja & Jawatan Aplikasi
The PTO drive shaft sits between the rear of the tractor and the front of the implement — specifically, between the tractor’s PTO output stub (1 3/8″ 6-spline at 540 rpm or 1 3/8″ 21-spline / 1 3/4″ 20-spline at 1000 rpm) and the input shaft of the Krone BiG Pack 1290 or other powered attachment. Power flows in one direction: enjin traktor → kotak gear traktor → output PTO → aci → input laksana → alat kerja.
Secara mekanikal, aci mempunyai tiga zon, setiap satu melakukan tugas tertentu:
- Kedua-dua sendi universal pada setiap hujung, benarkan aci menghantar tork pada sudut tertentu. Apabila traktor berpusing dan alat tersebut bersendi di atas tanah yang tidak rata, setiap pemasangan silang dan galas mengimbangi ketidaksejajaran sudut tersebut — tetapi hanya sehingga kira-kira 25° setiap sambungan untuk sambungan standard, atau 35–45° untuk sambungan CV sudut lebar.
- Tiub teleskop di tengah biarkan aci berubah panjang. Apabila traktor menjulang tinggi dan alat jatuh ke belakang, tiub luar betina dan tiub dalam jantan akan terpisah; apabila traktor dan alat kembali sejajar, tiub akan kembali bersama. Profil bintang, lemon atau spline yang ditarik sejuk memastikan tiub jantan dan betina terkunci dalam fasa putaran walaupun ia meluncur.
- Peranti keselamatan (bolt ricih, geseran atau klac ratchet) terletak di hujung alat dan merupakan barisan pertahanan terakhir. Apabila tork alat melebihi nilai yang dikalibrasi klac — contohnya apabila penanam putar melanggar akar yang tertimbus — klac tergelincir, terpotong atau terlepas, sekali gus memisahkan alat daripada traktor sebelum kotak gear boleh rosak.
Pelindung plastik dua keping adalah mekanikal, bukan simbolik. Setiap kon plastik disokong oleh kolar galas tertutup yang dipasang pada kuk berputar; kon itu sendiri tidak bergerak semasa aci berputar di dalamnya. Rantai kecil menambat pelindung pada titik tetap pada traktor atau alat supaya pelindung tidak dapat berputar walaupun kolar galas haus. Jika rantai hilang, keseluruhan sistem keselamatan akan gagal: pelindung berputar bersama aci, dan sebarang pakaian atau anggota badan longgar yang bersentuhan dengannya akan dililit pada RPM operasi. Sentiasa pastikan rantai telah disangkut sebelum mengaktifkan PTO.

Panduan Pemilihan — Cara Memilih Aci PTO yang Tepat
Gunakan senarai semak pra-pembelian 10 langkah di bawah untuk mengesahkan setiap dimensi sebelum membuat pesanan. Malangnya, aci PTO yang salah merupakan salah satu item pemulangan dan penggantian yang paling biasa dalam perdagangan pertanian-driveline, dan hampir setiap kes pemasangan yang salah berpunca daripada langkah yang terlepas daripada senarai ini.
| Langkah |
Tindakan |
Apa yang Perlu Disahkan |
Petua Pengamal |
| 1 |
Ukur stub PTO traktor |
Kenal pasti “1 3/8″ 6-spline”, “1 3/8″ 21-spline” atau “1 3/4″ 20-spline” menggunakan tolok spline atau vernier. |
Spline yang tidak sepadan adalah ralat susunan yang paling biasa. |
| 2 |
Aci input alat ukur |
Prosedur yang sama pada input kotak gear alat — perhatikan corak spline dan sebarang alur penguncian. |
Splin hujung pelaksanaan selalunya berbeza daripada hujung traktor. |
| 3 |
Ukur panjang tertutup |
Dengan alat pada jarak operasi minimum, ukur bahu ke bahu kedua-dua kuk. |
Panjang tertutup menetapkan panjang minimum yang mesti dimampatkan oleh aci anda. |
| 4 |
Ukur panjang yang dipanjangkan |
Angkat, lipat atau putar alat kepada geometri maksimum dan ukur semula. |
Panjang lanjutan menetapkan pertindihan minimum yang perlu dikekalkan oleh tiub teleskop. |
| 5 |
Tentukan keperluan kuasa |
Gunakan kW yang dinilai pada alat dan kelajuan PTO traktor (540/1000 rpm) untuk mengira siri yang diperlukan. |
Saiz siri ini di bawah spesifikasi menyebabkan kerosakan akibat keletihan dalam satu musim. |
| 6 |
Pilih peranti keselamatan |
Padankan alat: bolt ricih untuk beban stabil, geseran untuk beban kejutan, roda bergilir untuk beban lonjakan sekali-sekala. |
Jenis klac yang salah sama ada gagal melindungi atau tergelincir di bawah beban biasa. |
| 7 |
Pilih sambungan pantas yoke |
Pin tekan (lebih ringan), pin bolt (tugas berat), kolar bola (pemutus sambungan yang kerap) atau pelepasan cepat (pemutus sambungan setiap jam). |
Pilih untuk rutin harian pengendali, bukan pilihan yang paling murah. |
| 8 |
Sahkan sudut operasi |
Berjalan pada kedudukan alat terpanjang dan terpendek, ukur sudut aci pada setiap sambungan. |
Pengoperasian berterusan melebihi 35° setiap sambungan mengurangkan separuh jangka hayat. |
| 9 |
Tentukan sistem pengawal |
Pelindung standard ISO 5673 sesuai dengan 95% bekas; persekitaran haus tinggi mungkin memerlukan pelindung tugas berat tiga kon. |
Pengawal yang rosak mesti diganti — ia bukan pilihan. |
| 10 |
Sahkan keperluan pensijilan |
Pelanggan EU memerlukan CE; pembeli Australia merujuk silang AS 2153; sesetengah pasaran memerlukan EAC. |
Ketidakpadanan pensijilan boleh menghalang pelepasan kastam. |
Pemilih Pantas 3 Langkah — Apabila Anda Tergesa-gesa
- Ukur — panjang tertutup dari permukaan rintisan PTO ke bahu input pelaksanaan, dengan pelaksanaan pada jarak operasi minimum.
- Padanan — corak spline di kedua-dua hujung + gaya yoke (pin tekan / pin bolt / pelepas pantas).
- Sahkan — jalur kuasa traktor (HP @ 540 atau 1000 rpm) dan pilih peranti keselamatan yang sepadan dengan alat (bolt ricih untuk beban stabil, geseran untuk kejutan).
Jika mana-mana satu daripada tiga perkara tersebut tidak pasti, hantarkan gambar stub PTO traktor anda dan aci input alat, dengan pita pengukur yang boleh dilihat. Kami akan memberi maklum balas dengan SKU yang disyorkan dalam tempoh satu hari bekerja.
Panduan Pemasangan Langkah demi Langkah
⚠️ Keselamatan Didahulukan. Before any work, switch off the tractor engine, remove the key, engage the parking brake, and wait for all rotating components to stop. Never reach toward an unguarded PTO stub. Wear close-fitting clothing, safety boots and gloves throughout.
- Pre-installation safety checks. Engine off; key out of ignition; parking brake on; PTO disengaged at the cab lever. Confirm there is no one between the tractor and implement before beginning.
- Verify dimensions. With the implement at minimum operating distance, lay the new PTO shaft along the gap and confirm closed-length compression and spline-end matching. If the shaft is too long, do not force it — contact us for the correct length or for cut-to-fit instructions.
- Connect the tractor end first. Press the push-pin (or release the bolt-pin / quick-release collar), align the spline, push the yoke onto the PTO stub until the lock engages with an audible click. Pull back firmly to confirm the lock has seated.
- Connect the implement end. Repeat the same procedure on the implement input shaft. The two ends are not interchangeable — install the marked tractor-end yoke on the tractor, and the marked implement-end yoke on the implement.
- Anchor both guard chains. The plastic guard cones each carry a small chain. Hook each chain to a fixed point — never to the rotating shaft itself. The chain must hold the guard stationary while the shaft rotates inside it.
- Length verification. With the tractor and implement in their normal operating positions, confirm telescoping overlap is at least 1/3 of the male tube length. With the implement at maximum reach, confirm the tubes are not bottoming out (no metal-to-metal contact at minimum overlap).
- Operating-angle check. Walk the implement through its full geometry (lift, lower, fold, turn). Each universal joint should not exceed 35° at any point under load — for sustained operation, keep angles under 25° per joint.
- Initial lubrication. Apply 4–6 pumps of EP-2 lithium grease to each cross-and-bearing nipple, rotating the shaft 90° between pumps to fill all four needle bearings. Apply a thin film of grease to the male telescoping tube. Wipe excess.
- Final pre-start check. All chains hooked? Both yoke locks engaged? Guards intact? Operator clear? Only then enter the cab, start the engine and engage PTO at idle RPM for the first 10 seconds before ramping up.
PTO Troubleshooting Guide — 10 Field-Tested Fixes
Common PTO issues, their root causes, the field fix, and the prevention step that stops them coming back.
| Symptom |
Likely Cause |
Penyelesaian |
Prevention |
| Shear-bolt failing repeatedly within minutes of starting |
Wrong grade or diameter of bolt installed; implement bearing seized or transmission jammed; impact load from rocks in the field |
Verify the bolt is the correct grade specified on the clutch label (typically 8.8 or 10.9); inspect the implement for free rotation; clear any obstructions before re-engaging PTO. |
Carry only the specified shear bolts in the toolkit and never substitute hardware-store bolts of unknown grade. |
| Tractor rear axle vibrating at PTO speed |
Shaft out of dynamic balance after repair; cross-pair installed 90° out of phase; bent tube |
Send the shaft to a balancing shop; verify both yokes are aligned ‘in phase’ (the lugs of both yokes parallel); replace any bent tube. |
Mark both yokes with a paint stripe before disassembly so they can be re-installed in their original phase relationship. |
| Friction clutch slipping under normal load |
Friction discs glazed from prolonged slip, oil contamination on the friction surfaces, or springs fatigued |
Loosen the spring bolts, separate the discs, lightly hand-sand the friction faces with 80-grit paper, clean with brake-cleaner and re-tension to the torque on the clutch label. |
Run a 10-second slip routine at the start of every season to ‘bed-in’ the discs and verify spring tension annually. |
| Excessive grease ejected from cross at first start |
Over-greasing during last service; thermal expansion of grease in cold conditions |
Wipe excess grease away; if joint runs cool, reduce next service to 3 pumps per cross. |
In cold climates use a Grade 0 or 00 grease to prevent excessive ejection on cold starts. |
| Free-wheeling/over-running clutch grabbing in reverse |
Pawl springs fatigued or pawl seats worn from sustained reverse-load contact |
Replace the over-running clutch as a sealed unit and verify implement decelerates smoothly without back-driving. |
On hay and silage rakes, idle the engine for 5 seconds before disengaging PTO so the over-runner can release naturally. |
| Cross & bearing running hot to the touch |
Insufficient grease, contaminated grease, or operating angle exceeding 35° at full load |
Re-grease with a fresh EP-2 lithium charge; reduce operating angle by raising or lowering the implement; replace bearings if seals appear glazed. |
Stick to the lubrication interval printed on the guard label and keep operating angles within design limits. |
| Visible torsion deformation along the tube length |
Sustained torque overload from a stalled implement; or an undersized shaft for the application |
Replace the entire tube section — a torsioned tube cannot be straightened safely; revisit the shaft sizing. |
Listen for the characteristic ‘crack’ of a stall and disengage PTO immediately; never try to ‘power through’ a jammed implement. |
| Shielding rotating with the shaft instead of remaining stationary |
Bearing collars on the guard worn or seized; safety chain missing or broken |
Replace the bearing collars on the inner and outer cones; install or replace the safety chain hooking the guard to a fixed point. |
Check the safety chain at every connection — a stationary guard is the single biggest factor in PTO-related injury prevention. |
| Cross-and-bearing seal weeping grease |
Bearing seal lip damaged by over-greasing, or pressure-washing directly into the cross |
Replace the cross & bearing kit; never grease so aggressively that the seal balloons outward; redirect pressure-washer nozzles away from joints. |
Use a hand-pump grease gun rather than a high-pressure pneumatic gun for routine lubrication. |
| High-load power transmission insufficient — tractor lugs down |
PTO shaft under-rated for the implement; tube wall thickness too thin; clutch slipping unnoticed |
Re-evaluate the implement’s torque draw and step up to the next series shaft; verify clutch is engaging fully and not slipping. |
When in doubt, oversize the shaft series rather than under-spec — the marginal cost of a heavier model is far less than a field failure. |

Three questions we hear most often from buyers — tap to expand.
❓ Which international standards and certifications do your PTO shafts meet?
Aci PTO kami direka bentuk dan diuji mengikut ISO 5673-1 dan ISO 5673-2 (piawaian antarabangsa yang mengawal aci pemacu PTO pertanian dan pelindungnya), EN 12965 (keperluan PTO traktor dan jentera Eropah) dan ASAE S331.5 / ISO 500 (dimensi antara muka PTO). Bagi pasaran Australia, kami mematuhi panduan keselamatan traktor AS 2153. Kilang kami memegang pensijilan ISO 9001:2015 dan penandaan CE digunakan pada setiap sistem pelindung. Atas permintaan, kami boleh membekalkan penandaan EAC untuk Kesatuan Kastam Eurasia, laporan RoHS dan sijil kebolehkesanan bahan untuk tiub, palang dan yoke.
❓ Can your PTO shafts be used as direct replacements for branded shafts such as Bondioli & Pavesi or Walterscheid?
Yes — we manufacture interchangeable shafts that match the dimensional, spline and torque specifications of leading European and North-American brands. Customers commonly cross-reference our T-series, L-series, S-series and wide-angle shafts to Bondioli & Pavesi, Walterscheid, Comer, Weasler and Neapco part numbers. We will gladly map your existing model number to a compatible shaft if you provide the brand part number, working length, yoke types and any clutch settings. Please note that all branded names are used solely for cross-reference; we are not affiliated with those manufacturers and do not represent ourselves as their authorised supplier.
❓ What kind of warranty and after-sales support is included?
Each PTO shaft carries a 12-month workmanship warranty from the date of invoice covering yokes, cross & bearing kits, tubes and shielding. Wear items damaged through misuse — such as a friction clutch operated outside its torque rating — are replaced at cost. Our spare-parts library carries every component used in production, so dealers can hold a small kit (cross & bearing, yoke, push pin, guard cone) and service most failures locally. We also provide free technical support over WhatsApp and email, including video walk-throughs of installation, lubrication and shear-bolt replacement.
