PTO Shaft for Mower – Reliable Power Where It Matters
The mower is a workhorse of modern farming, and its productivity depends entirely on the integrity of the PTO shaft connecting it to the tractor. Our mower PTO drive shaft is engineered for the specific torque, speed, and articulation demands of grass and hay cutting. With heat-treated components and precision-balanced joints, it delivers trouble-free operation across thousands of hectares.

Understanding PTO Shaft Mechanics for the Mower
In grass and hay cutting, the mower draws all its operating power through the PTO shaft. This shaft is essentially a rotating driveline that connects the tractor’s PTO output to the implement’s working mechanism via a series of universal joints and a telescoping tube.
The tractor-side yoke slides onto the PTO stub (typically 1-3/8" 6-spline or 1-3/4" 6-spline), locking into place. As the PTO engages, the stub begins to rotate, sending power through the shaft. The U-joints at each end allow the shaft to flex as the tractor and mower move independently over terrain.
The telescoping section—made from a profiled tube (lemon, star, or triangular cross-section)—slides freely to absorb changes in the distance between tractor and implement. On the mower end, the shaft connects to a gearbox or direct-drive mechanism that converts PTO speed and torque into the specific motion needed for grass and hay cutting.

Installation Guide – PTO Shaft on Mower
⚠ Peringatan: Selalu matikan mesin traktor, lepaskan PTO, dan tunggu hingga semua bagian yang berputar berhenti sepenuhnya sebelum memulai pemasangan. Ikuti petunjuk keselamatan dari produsen traktor dan alat pertanian Anda.
Langkah 1: Inspeksi Pra-Pemasangan
Unpack the PTO shaft and inspect all components for shipping damage. Verify that the yoke splines, U-joints, profile tubes, and safety guards are in perfect condition. Confirm the shaft series and length match your mower requirements.
Langkah 2: Atur Panjang Poros yang Tepat
Park the tractor with the mower in its normal working position. Measure the distance from the tractor PTO stub face to the implement input shaft face. Adjust the telescoping tubes so that the shaft closed length is approximately 10–15 mm shorter than this measured distance to allow for suspension travel.
Langkah 3: Hubungkan Yoke Ujung Traktor
Geser dudukan ujung traktor ke poros PTO. Pastikan alur terpasang sepenuhnya dan mekanisme pengunci (pin tekan atau kerah) berbunyi klik. Periksa apakah tidak ada pergerakan radial yang berlebihan.
Langkah 4: Menghubungkan Implement-End Yoke
Align the implement-end yoke with the mower’s input shaft. Slide the yoke onto the splines or into the keyway and secure with the appropriate locking mechanism. If a torque limiter is present, ensure it is correctly oriented per the manufacturer’s markings.
Langkah 5: Pasang Pelindung Keamanan
Geser kedua bagian pelindung ke atas poros dan sambungkan menggunakan klip yang disediakan. Pasang rantai penahan pelindung—satu ke batang penarik traktor atau titik tetap, satu ke rangka alat pertanian. Pelindung harus dapat berputar bebas dan tidak boleh dipasang pada komponen yang berputar.
Langkah 6: Pemeriksaan Akhir & Uji Coba
Pastikan semua sambungan terpasang dengan aman. Hidupkan mesin traktor dan aktifkan PTO pada kecepatan idle. Amati poros untuk melihat apakah putarannya lancar, getaran yang tidak biasa, atau suara bising. Tingkatkan kecepatan secara bertahap hingga kecepatan operasi. Periksa kembali semua pengencang setelah satu jam pengoperasian pertama.
PTO Shaft Troubleshooting Guide for Mower
| Gejala | Kemungkinan Penyebab | Tindakan yang Disarankan |
|---|---|---|
| Pelindung pengaman tidak berputar bebas | Bantalan pelindung macet; pelindung rusak atau tidak sejajar | Ganti bantalan pelindung; luruskan atau ganti bagian pelindung; pasang kembali rantai dengan benar. |
| Poros PTO terputus selama pengoperasian | Kerah pengunci aus; alur penahan pada poros PTO rusak. | Ganti dudukan pelepas cepat; periksa dan perbaiki alur poros PTO jika aus. |
| Excessive vibration during operation | Worn U-joint cross bearings; shaft out of balance; excessive operating angle | Replace U-joint cross kit; check yoke alignment; reduce operating angle to <25° |
| Penumpukan panas pada sambungan U | Pelumasan tidak memadai; sudut operasi berlebihan; kerusakan bantalan. | Segera lumasi sambungan U; kurangi sudut pengoperasian; ganti kit silang jika bantalan rusak. |
| Poros tidak akan memanjang dengan mulus. | Korosi atau kotoran di dalam tabung profil; pelumasan yang tidak memadai. | Bersihkan dan lumasi tabung profil; ganti jika terlihat goresan. |
| Bunyi klik atau ketukan pada kecepatan rendah | Bantalan jarum sambungan U aus; dudukan longgar pada poros PTO | Ganti rakitan sambungan U; periksa keausan spline dan mekanisme penguncian yoke. |
| Overload clutch slipping under normal load | Clutch plates worn or contaminated; incorrect torque setting | Adjust clutch torque setting; replace clutch plates if worn or oil-contaminated |
| Baut geser berulang kali patah | Penyumbatan tidak diatasi; jenis baut yang digunakan salah; ukuran poros terlalu kecil | Bersihkan sumber penyumbatan; gunakan hanya baut dengan mutu yang ditentukan; pertimbangkan untuk mengganti ke seri poros berikutnya. |

Frequently Asked Questions – PTO Shaft for Mower
❓ Can I use a 540 rpm shaft on a 1000 rpm PTO?
No. Using a shaft rated for 540 rpm on a 1000 rpm PTO will result in excessive speed, dangerous vibration, and potential catastrophic failure. Always match the shaft speed rating to both the tractor PTO setting and the implement requirement.
❓ Garansi apa yang Anda tawarkan untuk poros PTO?
Semua poros PTO memiliki garansi pabrik terhadap cacat material dan pengerjaan. Ketentuan garansi berbeda-beda tergantung serinya. Hubungi tim kami untuk detail garansi spesifik yang berlaku untuk pembelian Anda.
❓ Apa penyebab kegagalan sambungan U-joint sebelum waktunya?
Penyebab umum meliputi pelumasan yang tidak memadai, sudut pengoperasian yang berlebihan (lebih dari 25°), pengoperasian pada kecepatan lebih tinggi dari yang ditentukan, ketidaksejajaran antara traktor dan alat pertanian, dan kurangnya inspeksi rutin. Mengikuti jadwal perawatan yang direkomendasikan secara signifikan memperpanjang masa pakai sambungan U.
❓ Will this shaft fit my tractor and mower?
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 mower make/model, and our team will confirm compatibility before dispatch.
❓ What PTO shaft series do I need for my mower?
For most mower applications in the 30–90 HP range, we recommend the T2 / L2 (Light-medium duty) or T3 / L3 (Medium duty) series. If you operate near the upper end of this range or in particularly demanding conditions, consider stepping up to the S6 (Standard) series for additional safety margin.
❓ 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.
❓ Can I upgrade my existing mower 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.
❓ 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.
