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.
🏆 Extended Warranty
We stand behind our products with an industry-leading warranty, reflecting our confidence in the durability and reliability of every PTO shaft we supply.

Targeted Installation Procedure – Hayrake PTO Shaft
⚠ 安全第一: PTOを解除し、エンジンを停止し、イグニッションキーを抜き、駆動系を作業する前にすべての可動部品が完全に停止するまで待ってください。ぴったりとした衣服や手袋など、適切な個人用保護具（PPE）を着用してください。
フェーズ1：準備
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.
フェーズ2：長さの検証
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).
フェーズ3：トラクター接続
トラクター側のヨークをPTOスタブに完全に押し込みます。クイックリリースカラーが保持溝にカチッとはまるはずです。ヨークを後ろに引いて、ロックされていることを確認してください。プレーンボアヨークを使用する場合は、せん断ピンを挿入し、割りピンで固定します。
フェーズ4：接続の実装
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.
フェーズ5：ガードの取り付け
2つのガード半分をシャフトの周りに組み立てて、クリップで留めます。回転防止チェーンを取り付けます。1つはトラクターの固定ポイントに、もう1つは作業機のフレームに取り付けます。ガードがシャフトやヨークのどの部分にも接触することなく、手で自由に回転することを確認してください。
フェーズ6：運用テスト
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.

Frequently Asked Questions – PTO Shaft for Hayrake
❓ How do I measure the correct closed length?
Hitch the implement to the tractor in its normal working position. Measure the straight-line distance from the face of the tractor PTO stub to the face of the implement input shaft. The shaft closed length should be approximately 10–15 mm less than this measurement.
❓ 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.
❓ Are your PTO shafts balanced?
Yes. All our PTO shaft assemblies are dynamically balanced during manufacture. This reduces vibration, extends bearing life, and provides smoother operation compared to unbalanced aftermarket alternatives.
❓ How often should I grease the PTO shaft?
Grease all U-joint nipples every 8–10 hours of operation, or at the start of each working day. Grease the telescoping profile tubes at the same interval. Use EP2 lithium-complex grease or as recommended in your product manual.
❓ 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.
❓ What is the difference between a shear bolt and a friction clutch?
A shear bolt is a sacrificial pin that breaks when torque exceeds its rated capacity. It is inexpensive but requires manual replacement after each event. A friction clutch slips when overloaded and automatically re-engages when the overload clears, offering uninterrupted operation in applications prone to frequent shock loads.
❓ Can I upgrade my existing hayrake PTO shaft to a heavier series?
In most cases, yes. As long as the yoke spline sizes match your tractor PTO stub and implement input shaft, you can upgrade to a heavier series for increased torque capacity and durability. Our technical team can advise on the correct upgrade path for your equipment.
