Power take-off (PTO) Shaft

PTO Shaft and Power Take-Off Components — OEM Agricultural Driveline Manufacturing

A power take-off (PTO) shaft transmits engine power from a tractor or vehicle to an attached implement or driven machine. It is one of the most fundamental mechanical interfaces in agricultural equipment — standardised in dimensions and operating speed to allow interchangeability across tractor and implement brands worldwide.

SMI manufactures PTO shafts, yokes, safety shields and associated driveline components to customer drawing and specification. Production covers casting, machining, surface treatment and export packaging — with finished assemblies supplied to agricultural equipment manufacturers and distributors in Europe and other global markets, including supply to customers in Germany.

Technical Background — PTO Standards and Configurations

Agricultural PTO shafts are standardised under ISO 500, which defines shaft dimensions, spline profiles, operating speeds and safety requirements. Three principal configurations are in common use:

Type Speed Splines Shaft Diameter Application
Standard 540 RPM 6 1⅜ inch General agricultural implements
High speed — small 1000 RPM 21 1⅜ inch Higher power applications
High speed — large 1000 RPM 20 1¾ inch High torque applications

SMI can manufacture to any of these standard configurations or to customer-specified non-standard profiles. Spline dimensions, shaft length, yoke type and safety shield configuration are all customisable to the specific implement or equipment requirement.

Components Supplied

PTO Shafts — Complete Assemblies

Complete PTO shaft assemblies comprising inner and outer telescoping tubes, universal joints, yokes and safety shields. Shaft length, tube diameter, joint angle capacity and safety shield type are specified to the customer’s implement design. Standard yellow finish or alternative surface treatments available.

Yokes and Quick-Release Connectors

Cast and forged yoke components in standard and custom configurations — including push-pin, bolt-on and quick-release locking types. Spline bore dimensions manufactured to ISO 500 or customer specification. Available in standard silver/natural finish or painted to customer colour requirement.

Safety Shields

Plastic safety shields for PTO shaft assemblies — manufactured to ISO 500 safety requirements. Standard black configuration or custom colour. Shield geometry designed to the specific shaft assembly dimensions.

Spare Parts and Sub-Components

Individual universal joints, cross kits, bearing cups and yoke components available as spare parts supply alongside complete shaft assemblies. All parts manufactured to the same drawing and specification as the original assembly.

Manufacturing and Export Capability

The gallery images above show SMI’s PTO shaft production and export preparation process — from painted shaft assemblies on the production line through to completed export packaging. Key manufacturing stages include:

  • Casting and forging — yoke and component manufacture to dimensional drawing
  • Machining — spline cutting, bore machining and surface finishing to specified tolerances
  • Surface treatment — powder coating and paint finishing, standard yellow or customer-specified colour
  • Assembly — complete shaft assembly with universal joints, safety shields and end fittings
  • Export packaging — wooden frame pallet with plastic wrapping, labelled for export, ocean freight ready

Finished assemblies are manufactured in China and exported globally. SMI’s production capability supports both small development orders and large-volume OEM supply programmes.

OEM and Custom Supply

SMI’s PTO shaft manufacturing capability is available to agricultural equipment manufacturers and distributors requiring:

  • OEM supply to drawing — shaft assemblies manufactured to the customer’s engineering drawing or CAD model
  • Custom configuration — shaft length, spline profile, yoke type, joint angle, surface finish and shield colour to specification
  • Branded packaging — customer branding on shaft assemblies and packaging
  • Spare parts programmes — ongoing supply of replacement components alongside new shaft assemblies
  • Development support — SMI can assist customers in specifying the correct shaft configuration for new implement designs

Typical Applications

  • Rotary mowers and flail mowers
  • Balers and forage harvesters
  • Spreaders and sprayers
  • Tillers and cultivators
  • Pumps and generators driven from tractor PTO
  • Industrial and truck-mounted applications — water pumps, blowers, winches, compactors

Hammer Crusher Parts

The Handling Materials of Hammer Crusher:
Hammer crusher is used for crushing medium hard materials with weak abrasiveness, and the compression strength of the materials to be crushed should not exceed 100MPa, and the water content should be lower than 15%. The materials of hammer crusher are coal, salt, chalk, gypsum, tile and limestone and also fiber structure and broken wood and paper with strong elasticity and tenacity.

Features:
1. The working hammer adopts new technology for casting, so that it is wear resistant and impact resistant.
2. The granularity can be adjusted according to the requirement of the customers.
3. Hammer crusher has a sealed structure which solves the problems of powder dust pollution in the crushing workshop and ash leakage of the machine.
4. This crusher has the advantages of attractive appearance, compact structure and few easy-wearing parts and convenient maintenance.

Working principle:
The electromotor drives the rotor to rotate with high speed in the crushing chamber. The materials are fed into the machine from the upper feeding mouth and are crushed under the hitting, impacting, cutting and grinding of the hammer which is moving with high speed. On the bottom of the rotor, there is sieve plate and the crushed materials that is smaller than the screen size are discharged from the sieve plate, and the coarse particles bigger than the screen size are retained on the sieve plate to be hit and ground again by the hammer and finally be discharged from the machine from the sieve plate.

The Application and Usage of Hammer Crusher:
Hammer crusher, which is also called hammer mill or hammer crusher machine, is widely used for crushing the medium hard and crisp materials in mine, cement, coal, metallurgy, building material, highway and chemical industry.

All hammer crusher parts supplied by Sino Mahince Industry are made in China. The hammer crusher parts including hammer crusher spare parts which Sino Machine Industry supplied were produced per customer’s drawings or specifications.

Our fixed jaw plates and cone liners are engineered to significantly improve wear life, leveraging decades of application expertise and on-site experience to tailor them to specific machine requirements.

All our heavy-duty parts—from heavy-duty castings and forgings to critical spare parts like crusher components, pumping unit gearboxes, and Chute Sidewall—are manufactured in China. Every part, whether standard or custom, is produced strictly according to customer drawings, specifications, or unique operational needs.

Sino Machine Industries ha desarrollado una amplia gama de nuevas piezas resistentes, incluyendo piezas de trituradora (como placas de mandíbula fija y revestimientos de cono), cajas de engranaje para unidades de bombeo (maquinaria petrolera) y pared lateral de canal (equipo de soporte mecánico para minas de carbón).

Nuestras placas de mandíbula fija y revestimientos de cono están diseñados para mejorar significativamente la vida útil contra el desgaste, aprovechando décadas de experiencia en aplicaciones y conocimientos sobre el terreno para adaptarlos a las necesidades específicas de cada máquina.

Todas nuestras piezas resistentes —desde fundiciones y forjados resistentes hasta repuestos críticos como componentes de trituradora, cajas de engranaje para unidades de bombeo y pared lateral de canal— se fabrican en China. Cada pieza, ya sea estándar o personalizada, se produce estrictamente según los dibujos, especificaciones o necesidades operativas únicas del cliente.
