Agricultural PTO Drive Shaft
A PTO shaft is a common piece of equipment in agricultural machinery. This accessory allows agricultural machinery to turn the wheels of other machinery. A PTO is an important part of a tractor, allowing you to control the speed and power of your vehicle.
Applications of PTO shaft
PTO shafts are used to power various pieces of machinery. Most agricultural equipment needs some form of power takeoff system to convert the rotational energy from the engine to the implements. A PTO drive shaft is the most common solution. These mechanical devices convert engine energy into hydraulic pressure. PTO shafts are used to pull heavy loads. But when not used properly, they may become defective and cause a faulty machine. If you own an agricultural tractor, you may be wondering how to make the most of your PTO shaft. This gearing system converts the power of the main tractor to the rotation of a PTO drive shaft. In addition, PTO shafts are useful in agricultural practices because they can be connected to a wide variety of work equipment. Here are some of the most common agricultural applications for PTO shafts.
PTO Shaft for Agricultural Machinery
Power-take-off shafts (PTOs) were developed to provide farming implement manufacturers and tractor manufacturers with a common method of powering implements. As the name implies, these shafts are designed to take power away from the engine, through the transmission.
Most often found in farming equipment, PTO shafts provide power for attached farming implements, which are basically anything a farming tractor pushes or pulls. This includes rotary tillers, finish mowers, sickle mowers, hay tedders, post hole diggers, fertilizer spreaders, and the ever-popular manure spreaders. PTOs can also be used to power electrical generators, which are attached in the same way as regular farming implements. PTO shafts in tractors can be found in front or rear-mounted applications. In addition, live or continuous PTOs do exist, which provide power to the attached implement, even without the tractor is in motion. This is generally accomplished by using a separate transmission for the PTO and the tractor.

What Is a PTO Shaft?
PTO shafts are the connection points for transferring the power from larger tractors to implements. PTO (power take-off) shafts are splined shafts sticking out of the rear of the tractor (compact utility tractors), splined recesses in the rear of the tractor (garden tractors) or splined shafts protruding from some point underneath the tractor. There are industry standards for the speed of these shafts. The recessed PTO on garden tractors turns at 2,000 rpm. It uses the recessed design to prevent connecting an implement designed for the 540 rpm PTO used on compact utility tractors. Implements connect to the PTO shafts using a drive shaft with two or three universal joints to provide flexibility.

The PTO shaft transfers power from the tractor’s engine to the implement, such as a tiller or a harrow. Because of this, many pieces of farm equipment have no independent power. By getting PTO shafts, you’ll be able to get the right fit and start operating your farm machinery without any problems.
Our PTO drive shafts are made of high-quality material. PTO shafts are made from metal and are enclosed in a plastic sleeve, preventing accidental contact with the high-horsepower turning shaft.

Three Main Types of PTO Shafts
The kind of PTO shafts you pick is dependent on the work you’re expected to perform. If you’re plowing or mowing or shredding, you’ll need a PTO shaft that is ideal for every job and protects your equipment from unnecessary stress, hits or tension.
Non-Shear PTO Shaft
This is designed to work with equipment that isn’t designed to withstand sudden stops. It’s a yoke to yoke arrangement. It can be utilized for larger mowers since the motions are effortless and there shouldn’t be any resistance or stoppage.
Shear Pin PTO Shaft
It can be used in conjunction with other equipment, such as chipper. The yoke at the end is made of two pieces, and it uses shear pins to hold them in place for operation. The pin absorbs shock when there is an abrupt stop, in order to avoid damage to the driveline.
Slip Clutch PTO Shaft
Slip clutch is made to shield your tractor as well as the connected equipment from damage by sliding internally, allowing the movement of an object when it hits. For instance, when changes in the season, stones and rocks are brought to the surface and when you come into contact with them, you’ll want to absorb the shock so that you don’t damage the gearbox.
How Do PTO Shafts Work?
PTO shafts work by allowing a tractor to turn at high speed. A PTO shaft consists of a telescoping tube, a universal joint, and yokes. It is usually protected by a plastic shield and a chain. When attached to an implement, the PTO shaft allows the tractor to rotate at two different speeds. Typically, these shafts are used in wood chippers, rotary tillers, and mowers.
A PTO shaft works by tapping energy from the tractor’s engine. This energy is then transferred to a hydraulic pump, which then builds pressure and moves hydraulic fluid. This movement, in turn, moves energy from the tractor’s engine to the implement. A power takeoff shaft is more effective in larger tractors.
PTOs can rotate in either direction, either clockwise or counterclockwise. It is important to note that the direction of rotation should be standardized. This is so that any damage that can occur is minimized. If the rotation direction is distorted, the PTO can cause damage to the implements it is attached to. For this reason, PTOs should not be used in reverse for too long.

How to Measure the Parts of the 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.
PTO Shaft Installation Instruction
Install assembly
1 press-fit plastic pipe and plastic cap,
2 fill the groove on the horn with oil
3. Slide the nylon bearing into the groove
4. Align nylon bearing and plastic protective cover
Disassembly
1. remove the nylon bearing clamp (three places) with a screwdriver, and then separate the steel pipe and plastic protective cover.
2. Take off the nylon bearing from the groove of the yokes.
3. repeat the above-mentioned steps for the other side.
Shortening the PTO Drive Shaft
1. Remove the safety shield.
2. Shorten the inner and outer tubes according to the required length, and the inner and outer tubes shall be shortened by the same length at one time
3. Deburr edges of the drive tubes with a file and remove all filings from the tubes.
4. Shorten the inner and outer plastic pipes according to the required length, and the inner and outer plastic pipes shall be shortened by the same length at one time.
5. Grease the internal drive tubes and reassemble them with a safety shield.
Check the minimum and maximum length of the driveshaft installed on the machine. In working condition, the drive tubes should overlap 2/3 length and the plastic tube should never be separated
Lubrication of the PTO Drive Shaft
Frequent lubrication is required. Grease the driveline shaft parts at hourly intervals as indicated on the drawing left.
The same assembly method is used for both types of safety shields.
Cautions When Using PTO Shafts
PTO shafts are moving parts and need to be treated cautiously. Since they do provide a lot of power, they can and will rip or crush anything that tries to mess with them. Guards and shields have been manufactured to reduce the likelihood of serious or often fatal injuries, but care still needs to be taken when using PTO-powered equipment.
- Make sure the PTO shaft is shielded. This includes the driveline shield that covers the implement driveline, and the master shield which covers the universal joint and PTO stub shaft on the tractor.
Maintain the shield so it can work for you. PTO driveline shields are usually mounted on bearings, so they need to be maintained. Always REPLACE the shield when it is damaged or missing. - Keep a safe distance from it when in use. Keep others away, too. How far? A distance of twice your height is a good start.
- Remember, allow only those who absolutely must be in the area to be there. Keep all children away!
- Always pay attention to what is happening. Most PTO victims were caught by surprise.
- If something goes wrong — stop the machinery; take the PTO shaft out of gear, stop the engine and set the brake. Put the keys in your pocket before working on the machinery.
- When stopping the machinery for any reason — end of work, lunch, repairs, or communication — take the PTO shaft out of gear, stop the engine and set the brake.
