How a PTO Shaft Works on a Tree Shaker
The PTO shaft transmits rotational energy from the tractor’s rear PTO stub to the input shaft of the tree shaker. 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 mechanical fruit and nut harvesting, 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 tree shaker 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 Tree Shaker
⚙ Heat-Treated Components
Every yoke and U-joint cross in our tree shaker 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.

Installation Guide – PTO Shaft on Tree Shaker
⚠ Warning: Always shut down the tractor engine, disengage the PTO, and wait for all rotating parts to stop completely before beginning installation. Follow your tractor and implement manufacturer’s safety instructions.
Step 1: Pre-Installation Inspection
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 tree shaker requirements.
Step 2: Set Correct Shaft Length
Park the tractor with the tree shaker 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.
Step 3: Connect Tractor-End Yoke
Slide the tractor-end yoke onto the PTO stub shaft. Ensure the splines engage fully and the locking mechanism (push-pin or collar) clicks into place. Verify there is no excessive radial play.
Step 4: Connect Implement-End Yoke
Align the implement-end yoke with the tree shaker’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.
Step 5: Install Safety Guards
Slide the guard halves over the shaft and connect them using the supplied clips. Attach the guard retention chains—one to the tractor drawbar or a fixed point, one to the implement frame. The guards must be able to rotate freely and must never be attached to a rotating component.
Step 6: Final Check & Test Run
Verify all connections are secure. Start the tractor engine and engage the PTO at idle speed. Observe the shaft for smooth rotation, unusual vibration, or noise. Gradually increase to operating speed. Re-check all fasteners after the first hour of operation.

Frequently Asked Questions – PTO Shaft for Tree Shaker
❓ ¿Realizan envíos a zonas regionales y remotas de Australia?
Por supuesto. Realizamos envíos a todos los códigos postales australianos a través de las principales empresas de transporte. Las zonas regionales y remotas pueden tener tiempos de tránsito ligeramente más largos, pero trabajamos con varias empresas de transporte para garantizar una entrega fiable en todo el país.
❓ ¿Puedo usar un eje de 540 rpm en una toma de fuerza de 1000 rpm?
No. Usar un eje con una velocidad nominal de 540 rpm en una toma de fuerza (TDF) de 1000 rpm provocará una velocidad excesiva, vibraciones peligrosas y una posible falla catastrófica. Siempre ajuste la velocidad nominal del eje tanto a la configuración de la TDF del tractor como a los requisitos del implemento.
❓ ¿Se puede acortar el eje para adaptarlo a mi configuración?
Sí. Los tubos telescópicos se pueden cortar a una longitud menor con una amoladora angular o una sierra de corte. Asegúrese de que quede un solapamiento mínimo de 1/3 entre los tubos interior y exterior después del corte. Elimine las rebabas de todos los bordes cortados antes del reensamblaje.
❓ 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.
❓ What PTO shaft series do I need for my tree shaker?
For most tree shaker applications in the 80–350 HP range, we recommend the T5 / L5 (Heavy duty) or T6 / L6 (Super heavy duty) series. If you operate near the upper end of this range or in particularly demanding conditions, consider stepping up to the S8 (Wide-angle) series for additional safety margin.
❓ Can I upgrade my existing tree shaker PTO shaft to a heavier series?
En la mayoría de los casos, sí. Siempre que las dimensiones de las estrías de la horquilla coincidan con el eje de entrada de la toma de fuerza de su tractor y el eje de entrada del implemento, puede actualizar a una serie más robusta para obtener mayor capacidad de torsión y durabilidad. Nuestro equipo técnico puede asesorarle sobre la actualización más adecuada para su equipo.
❓ Will this shaft fit my tractor and tree shaker?
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 tree shaker make/model, and our team will confirm compatibility before dispatch.
❓ What warranty do you offer on PTO shafts?
All PTO shafts carry a manufacturer’s warranty against defects in materials and workmanship. Warranty terms vary by series. Contact our team for specific warranty details applicable to your purchase.
