Agricultural PTO Shafts

Main advantages of agricultural power output shaft

① High power transmission efficiency

Transfer up to 90% of the engine power directly from the tractor to the implement.

Compared to hydraulic or belt drive systems, it minimizes energy loss to the greatest extent possible.

② Multifunctionality and compatibility

Standard sizes (such as 1-3/8 inch, 1-3/4 inch axles) are suitable for most tractors and implements.

We offer two models, 540 RPM and 1000 RPM, to meet different power requirements.

Compatible with 1-5 types of attachment systems.

③ Durability and long lifespan

Made of high-strength steel with corrosion-resistant coating.

The telescopic design allows for length adjustment to prevent damage during operation.

Sealed universal joints can reduce wear caused by dust and moisture.

④ Security function

The PTO protective cover can prevent entanglement accidents (mandatory according to OSHA/ISO standards).

Shear bolts and sliding clutches can prevent overload and prevent equipment damage.

If the shaft gets stuck or jammed, the automatic release mechanism will release.

⑤ Easy to maintain and repair

Lubricating grease fittings can easily lubricate joints.

Modular design allows for quick replacement of worn parts (yokes, bearings, protective devices).

The universal joint reconstruction kit extends its service life.

⑥ Cost effectiveness

No need to install a separate engine on the equipment, reducing fuel and maintenance costs.

Can be exchanged between multiple machines to reduce spare parts inventory requirements.

Main applications in agriculture

① Hay and feed equipment

Rotary cutters and lawn mowers - efficiently cut grass and feed crops.

Hay baler (round and square) - compresses hay into bundles for storage.

Feed harvester - for harvesting crops such as corn or grass, used for silage feed.

② Cultivation and sowing

Rotary tiller - prepares planting soil by crushing clumps.

Seeding machine and seeder - ensure precise seed placement.

Plowing machine - removes weeds between crop rows.

③ Crop harvesting and processing

Combine harvester (spiral drive) - Move grains from the harvester to the trailer.

Grain Spiral Conveyor - Transfer harvested grains to storage bins.

Potato and sugar beet harvesters - providing power for excavation and sorting mechanisms.

④ Spraying and Fertilization

Boom Sprayers - evenly distribute insecticides/herbicides.

Fertilizer spreader - spreads granular fertilizer in the field.

⑤ Other agricultural tasks

Wood sawdust machine - deals with tree branches and farm waste.

Feed mixer - prepares a mixture of livestock feed.

Irrigation pump - provides power for the movement of water in the field.

Safety and maintenance tips

  Safety practices

Always engage the PTO at low RPM to avoid sudden jolts.

Check the protective cover before each use - do not operate damaged PTO shafts.

Keep loose clothing/hair away from the axis of rotation.

  Maintenance checklist

Lubricate the U-shaped joint every 50 hours using high-temperature grease.

Check if the splines or yokes are worn - if the clearance is too large, replace them.

Vertically store the shaft to prevent bending/twisting.
