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.

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.

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 Application

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.

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.

Slip Clutch PTO Shaft

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?

How Do PTO Shafts WorkPTO 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.

Cautions when Using PTO Shafts

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.

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.

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.
