The PTO shaft plays a vital role in transmitting power from the tractor to the connected implements. Parts of the PTO shaft include internal and external PTO yokes, universal joints, safety chains and safety guards. There are several different types of PTO shafts available, so you must choose the right PTO shaft for your equipment and application.

Each style includes a range of options, including bearing diameter, total cover to cover length, and snap ring options. The most accurate way to determine the correct series is to measure the outer diameter of the bearing cap and universal joint from one end of the cap to the other. The location of the snap ring is another determinant.

Part of PTO Shaft

Internal Yoke- There are two, located at both ends of the PTO shaft -tractor and implement. This is welded to the drive end.
Universal Joint- There are two, located at both ends of the PTO shaft.
External Yoke- There are two, located at both ends of the PTO shaft. It has a “Y” shape to connect to the U-joint and a female hole.
Safety Chains- The chains are used to secure the PTO shaft onto the equipment and onto the tractor.
Safety Shield- These cones are found on both ends.

Maintenance Of PTO shaft

Different applications require different maintenance schedules. The more abusive the environment, the more critical a new shot of grease can be. Steep drivelines will produce heat, thus degrading the lubricant more rapidly than a "flat" shaft will. Thrust also produces heat as well as forces that are contrary to torque. Inconsistent torque loads are harder on component parts than consistent ones.

By observing and inspecting your PTO on a regular basis, not only will you develop a "feel" for your maintenance needs, but you will most likely have a safer application too.

Frequent lubrication is required. Grease the driveline shaft parts at hourly intervals as indicated on the drawing left.Agricultural PTO Drive Shaft ep lubrication of pto shaft

The same assembly method is used for both types of safety shields.

How to measure the parts of the PTO shaft

S Series PTO Shaft

Measuring the parts of the shaft correctly is essential for selecting the correct PTO series dimensions. Each product needs to be measured in a specific way to be consistent with the standard size. Follow these steps to ensure that the correct measurements are obtained and to order the parts required for the tractor.

1. Measuring axis
To measure the shaft, first make sure that the shaft is in the closed position, at which time the shaft is the smallest. Use a tape measure to record the length of the outside of each yoke. This measurement is the closing length. Use this measurement to find the correct series size for the tractor horsepower. Make sure you also know if there are shear pins, clutches, or splined implement ends.

2. Measure the universal joint
When measuring the universal joint, measure the length from one end to the other. You also need to record the width of one end of the universal joint. Use these numbers to find the correct size of the universal joint.

3. Put them together
You need to make the above two measurements in order to find the PTO shaft parts suitable for your tractor and work normally. You can use the PTO yoke size chart to get the correct size or use our convenient PTO series discovery tool.
