Factory Direct PTO Shaft for Tractors and Agricultural Implements

Raydafon PTO Shaft — What We Do and How We Build It

Our Factory & Experience

• We focus on R&D and manufacturing of PTO Shafts and have deep experience in agricultural transmission systems.
• Our own factory sits in China's agricultural equipment industry cluster.
• We control the full process: material procurement, forging, machining, assembly, and testing.
• We supply a full range of PTO Shafts for mowers, rotary tillers, fertilizer spreaders, crushers, and more.
• Our products go to Europe, America, the Middle East, South America, and other developed agricultural markets.

Design Focus: Safety, Versatility, Durability

• Every drive shaft uses high-strength carbon steel pipe and forged steel forks.
• High strength and high torque — stable under heavy loads and high-frequency operation.
• We offer multiple international standard interfaces: Italian CE type, German WAL type, American ASAE standard, etc.
• This makes our shafts compatible with different agricultural machinery brands.

Safety Features We Build In

• Safety cover and torque-limiting clutch come standard — prevents overload damage and personal injury from jamming.
• Some high-end models support quick plug-in and pull-out — easy outdoor replacement and repair.
• Lubrication hole position is well designed with a sealing structure — extends lubrication cycles and reduces daily maintenance.
• Each set undergoes dynamic balancing and strength impact tests before leaving the factory — no abnormal vibration at high speeds.

Customization & Supply

• We serve agricultural machinery OEMs and retail channels — we know the differences across industries.
• We support sample customization and batch non-standard production.
• Flexible delivery cycles; our technical team helps with selection and interface matching.
• Standard models are always in stock and can ship the same day.

Where Our PTO Shafts Are Used

• Medium and large agricultural machinery
• Garden equipment
• Livestock feed machinery

How To Remove PTO Shaft From Gearbox

Removing a PTO drive shaft is not complicated, but doing it wrong can damage interface components or create safety hazards. Here is how we recommend doing it.

Before You Start

• Turn off the power source first.
• Make sure the equipment is completely shut down before you begin.

Check the Connection Type

• Most Raydafon PTO Shafts use a safety lock structure.
• Look for a push-type retaining ring or latch near the gearbox end.
• Some models use screws — you will need a hex or Torx wrench.

Removal Steps

• Grab the protective cover near the gearbox and pull it back carefully to expose the connection.
• For button retaining ring type: press the ring with one hand and gently pull the shaft out with the other.
• For screw type: unscrew the fixing screw, then pull gently.

What To Watch Out For

• Do not pull violently or shake too much — this can damage the gear spline or bearing oil seal.
• If the interface is rusted and stuck, spray lubricating rust remover, wait a few minutes, then try slowly.
• If still difficult, use a rubber hammer to gently tap the edge of the shell twice to help it loosen.

After Removal

• Check the spline interface for burrs, wear, or deformation.
• If you find a problem, do not install it hard — replace the accessory first.
• Raydafon PTO Shafts and Gearboxes have standard interfaces — align the direction and they go back without brute force.

If you hit an uncertain structure or a jam, contact Raydafon technical support. We can provide structural drawings or video guidance based on your model, so you do not delay farming schedules.

How To Measure PTO Shaft

Before replacing or customizing a PTO drive shaft, accurate measurement is critical. Wrong size affects installation and may cause poor operation or equipment damage. We recommend removing the shaft from the equipment before measuring.

1. Total Length

• Measure from end to end in the retracted state.
• That means from the outer edge of one fork to the outer edge of the other fork.
• Do not measure only the sheath length — that is inaccurate.

2. Spline Size (Output End Connector)

• Common spline specs: 1-3/8" 6 teeth, 1-3/8" 21 teeth, 1-3/4" 20 teeth, etc.
• Use a caliper to measure the outer diameter of the spline.
• Count the number of spline teeth.
• Raydafon connectors support multiple international standards for easy docking with different brands.

3. Pipe Diameter Type & Structure

• The middle part is usually a hexagonal tube, star tube, or square tube.
• This determines torque capacity and telescopic range.
• Use a vernier caliper to measure the distance between opposite sides (parallel sides for hexagonal tubes, tooth spacing for star tubes).
• Record the total telescopic stroke.

4. Safety Protection Structure

• Confirm whether the sleeve is complete.
• Check for anti-slip rings at both ends of the shaft.
• This helps determine whether the drive shaft can continue to be used.

If you are not sure how to measure, or worry about measurement error, take a photo and send your data to the Raydafon technical team. We provide dimension drawing confirmation, quick matching recommendations, or custom processing. You choose the right PTO Shaft and use it immediately after installation without modification.
