What is an Industrial PTO?
A power take-off (PTO) transmits the rotary power of an engine into hydraulic power for various applications. The industrial PTO connects with an industrial engine, sending a 1:1 ratio of power-driven off the output while maintaining the drive rotation.
Essentially, PTOs take the energy that would have otherwise been wasted and transfers it. Industrial PTO's utilize industrial SAE flywheel and flywheel housing standards to connect the PTO to the engine. A PTO consists of a complete clutch assembly with a shaft and bearings mounted in a cast-iron housing.
Industrial PTOs allow a customer to safely control the power source and offer a disconnect between the power source and subsequent use of that power. Essentially, a PTO puts horsepower to work. Without a power take-off, it would be necessary to add a second engine to provide the energy required to run hydraulic pumps and any other applications.
There are four main types of PTOs:
- Standard Friction
- Rubber Block Drive
- Straddle Bearing
- Remote Over Center

What is an Industrial PTO Used In?
There are essentially limitless possibilities for what applications have a PTO. However, the most commonly found applications are: irrigation pumps, hay processing equipment, slurry pump equipment, vacuum systems in grain handling, street sweepers, material vac-all equipment, fire protection equipment, levee storm surge equipment, municipal drainage districts, rock crushers, wood chippers, tub grinders, hydraulic mobile & stationary systems, air circulation systems, power generators, and conveyor drive equipment.
The above list may seem to be expansive, but it’s just a fraction of the total scope of applications using industrial power take-offs. PTO’s are used by some of the largest OEM’s in the business, including John Deere, Cummins, Deutz, Scania, Detroit, Perkins, Morbark, Bandit, Epiroc, Cedarrapids, Sandvik, Vactor, CBI, Case New Holland, Vermeer, CAT, Link-Belt, Allis-Chalmers, and Terex.
What are the Ranges of Sizes of Industrial PTO’s?
Industrial PTO’s come in a wide array of sizes to fit your application. PTOs range from a single plate to a three-plate option, 159 to 8400 lb-ft max input torque. There are sizes between that gap to service the full array of industrial SAE flywheel housings and flywheels that will meet the max input torque for your application.
