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.

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 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. A big tractor parked in the lot of one of the grocery stores I deliver ice to used a PTO shaft to power a salt spreader, attached to the rear of the tractor; PTO shafts in tractors can be found in front or rear-mounted applications, however. Another notable point is that 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.

Rotational speeds of farming PTOs are 540 rpm or 1,000 rpm.

PTOs are also used in aircraft, most notably in Lockheed Martin’s “new” F-22 Raptor Tactical Jet Fighter Aircraft, which utilizes stealth technology. Here they’re used to take power from the engines to produce electricity, which in turn provides power to many in-flight electrical systems. The unit also serves as a measurement for aircraft horsepower. Currently, it is used in only the left engine of the aircraft, as a failure of the PTO shaft would result in lost power to many required flight systems, which in turn produces a fiery explosion and a blackened patch of earth.

Rotational speeds for this unit are around the 18,000 rpm mark, considerably higher than those found on John Deere’s tractor.

Medium to heavy-duty single and multi-axle trucks also use PTO shafts. Applications here include powered winches (no, not wenches), salt spreaders, and small dumpers. Most likely the man who came to tow your car away used a PTO shaft to assist in towing your vehicle. Other specialized applications include providing power to the hydraulic systems of “snubbing trucks,” which pressurize and cap oil wells, in concrete pumping trucks, and by the telephone company to string wire. Construction companies may use PTO shaft powered air compressors, to provide a reliable, transportable supply of compressed air to the job site, and your local fire company probably uses PTO shaft power to pump the water they use as their weapon.

Rotational speeds for these types of PTO shaft applications vary, due to the variety of uses available, and the fact that many of them are controlled by pneumatic or manual gear shifters, which allow the operator to control the speed and torque provided to the PTO implement.

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 whenever one is using PTO-powered equipment.

Horizontal Shaft

Using the diagram, you will notice that there are three measurements that you will need to take for horizontal shaft engines, which are:

A.) Diameter
B.) Length
C.) Crankshaft Height
While the diameter measurement is obvious, be aware that you should take the length measurement from the oil seal out to the end of the crankshaft. Also, don’t overlook the importance of the crankshaft height (measurement C) as this distance will vary depending on engine model and brand. Depending on the application, this can be a critical measurement!
Horizontal Shaft

Note – The crankshaft height measurements are not included in the database so be sure to consult our line drawing section and make comparisons with your old engine.

Gear Reduction

As the name implies, gear reduction systems are used to reduce the output speed at the PTO while allowing the engine to maintain a sufficient speed that will deliver the power required for the application.
For example, an 8 H.P. engine used on a cement mixer would likely require a constant speed of around 3600 RPM to deliver peak power output. Obviously, the mixer itself cannot run at the same speed to be effective, so a gear reduction system is used to reduce the RPM at the PTO shaft. In this case, a 6:1 reduction system would output around 600 RPM (1/6th the engine speed) which would be in the correct range for the application. The internal gearing of the reduction unit also provides a massive amount of torque (power) that would otherwise be unavailable to the application from the engine alone.

Auxiliary PTO Shafts

Auxiliary PTO shafts can be found on both horizontal and vertical shaft engine models and are used to drive accessories on various types of equipment.
For example, the shaft shown in the image is used on a tiller application for the purpose of driving the reverse portion of the drive system. Depending on the application requirements, these shafts can protrude from the engine case in either a horizontal or vertical arrangement.

You should also be aware that they depending on the application, they will be configured to operate in either clockwise (CW) or counter-clockwise (CCW) rotation and cannot be interchanged. Shaft diameters and rotation info is included in the database where applicable.

How Can You Be Safe When Using PTO Shafts?
First, make sure the 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.
Next, 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.
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 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 out of gear, stop the engine and set the brake.

More Thoughts About PTO Shafts and Shields

The average replacement PTO shield should cost less than $50 according to North Dakota implement dealers, and will take less than two hours to install.
Can you get an ambulance ride to the hospital for less than $50?
How much health/hospitalization insurance can you buy for $50?
Can you buy an artificial arm or leg for $50 or less?
Can you buy a funeral for less than $50?
Can you look at a picture of your wife or family and say that PTO shields are not worth the cost or effort?
A replacement PTO shield is simply the cheapest insurance you can buy. The time spent to install and maintain a PTO shield is clearly the most valuable and productive time you can spend in your life!

When considering safe operation of mowers and conditioners, pto safety is vital. Always make sure the machine is hooked up correctly. Never attach a 540 rpm mower or conditioner to a 1000 rpm pto tractor. Operating a mower or conditioner at the wrong speed can cause machine failure and possibly injure you. Be extremely careful when working near pto shafts. Make certain that all safety shields are in place before you operate the mower or conditioner, or any other pto-driven machine. Rotating pto shafts that are not properly shielded are potential killers.

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. Midmount PTO shafts (Figure 3) may be specific to a given mower deck, but they should normally have a speed of 540 or 1,000 rpm. Implements connect to the PTO shafts using a drive shaft with two or three universal joints to provide flexibility.
