Size Importance
Regardless of what job you’ll be using a PTO shaft to complete, it’s important that you have the right size. The manufacturer should provide length recommendations to help you get an idea. When measuring a PTO shaft, use a tape measure and measure from the outside of each yoke to obtain the closed length. The series size should correspond with the amount of horsepower your tractor has. There are two different speeds used most commonly with tractor PTO shafts, the 540 (type 1) and 1000 (type 3) RPM.
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.

Lemon Tube
Without the PTO, a tractor cannot drive to complete its most basic of functions. Comprehending the different types of PTO shafts, parts, and their respective uses will allow for better practice with farm machinery. After all, you want an investment in the expensive and necessary equipment to last as long as possible.
How Does PTO Shaft Work?
The Power Take-Off shaft transfers power from your tractor to the equipment of your choice. The PTO driveline is where everything that needs power on a tractor derives its power from. PTO drivelines are often overlooked during routine maintenance checks but should not be ignored as they are crucial in operating farm equipment.
Wear and Tear
When you’re operating agricultural equipment, there’s inevitably going to be wear and tear. Areas to watch out for this especially are with the yoke ears or sides that can be damaged from working excessively at angles. If the angle exceeds forty-five degrees, the PTO should be disengaged.
Telescoping tubing and sections can also experience excessive wear if lubrication is lacking where the tubes overlap. Insufficient lubrication can also cause undue wear on shield bearings. Without proper lubrication, the friction between these bearings is too great. They should be lubricated every eight hours.
Damaged or Broken Parts
It’s important to pay attention when things start to run less smoothly, or you find your attention on an area of the machinery that ordinarily runs smoothly. Damage to parts can happen anywhere from telescope tubes to cross-bearing arms, or joints to yokes. Be aware of the shock load on your equipment and make sure that you are using the right type of PTO for the job you are attempting to accomplish. Heavy-duty equipment can take a lot of stress, but it’s important to stop if something isn’t right before damaging beyond a simple fix.
PTO Shafts for Agricultural Gearboxes
A PTO shaft is an extremely sophisticated mechanism that allows implements to draw energy from an engine. It works with a mechanical agricultural gearbox. A PTO shaft can be mounted on a vehicle’s transmission and is an essential part of the system. A high-quality PTO shaft should be durable enough to withstand torsion and minimize vibration. Ever-power manufactures a wide range of durable PTO shafts to meet all your requirements.
