1.What is a Flail Shredders PTO Shaft?
The Flail Shredders PTO Shaft is a key component that transmits power from the tractor to the grass shredder.
- It connects the tractor’s PTO output to the Alloway grass shredder, ensuring stable power transmission.
- The flexible slip or coupling design automatically slips under resistance or overload, protecting the equipment and the tractor’s gearbox.
- It is compatible with various models and RPM grass shredders, ensuring efficient and safe grass shredding operations.
2. Flail Shredders PTO Shafts Main Components
- PTO Input Shaft: Connects to the tractor or power source, carrying the main power.
- PTO Output Shaft: Connects to the shredder, providing power output.
- Center Housing: Contains a sliding coupling, allowing the input and output shafts to rotate independently.
- Sliding Clutch Assembly: A combination of friction plates, pressure plates, and springs provides overload protection.
- Safety Guard: Covers rotating parts to prevent accidental operation.
- Locking Ring: Secures the output shaft, ensuring reliable power transmission.
- Lubrication Nozzle: Facilitates regular lubrication of bearings and moving parts.
- PTO Universal Joint: Connects the output shaft to the shredder, enabling flexible transmission.
- Warning Labels and Instructions: Indicates operational risks and safe operating procedures.
3. PTO Shaft Compatibility & Clutch Selection Guide
3.1 Compatibility Information
Our Flail Shredders PTO Shaft is compatible with the following Alloway lawn shredder models: S15CD, S20CD, S22CD, S25CD, S27CD.
3.3 Clutch Matching Instructions
Our Flail Shredders PTO Shaft is compatible with the following Alloway lawn shredder models: S15CD, S20CD, S22CD, S25CD, S27CD.
- Clutch Matching Instructions
- Alloway grass shredders use different types of clutches at the connection point:
- Some models use dedicated clutches and must be replaced with the exact same specifications.
- Some models use universal clutches, with various alternatives available to suit different needs.
- The key criterion is whether the input shaft has a groove structure similar to that of a tractor PTO output shaft.
👉 If the input shaft does not have a groove, a clutch of the exact same model must be used for replacement.
