Frequent question: What does a PTO do on a tractor?

The Power Take-Off, most commonly referred to by its acronym, PTO, is a common form of mechanical power delivery in the mobile machine market. The PTO is a method of transferring high power and torque from the engine (usually via the transmission) of trucks and tractors.

How does a PTO work on a tractor?

The tractor’s stub shaft, often called the PTO, transfers power from the tractor to the PTO-driven machine or implement. Power transfer is accomplished by connecting a drive shaft from the machinery to the tractor’s PTO stub shaft. The PTO and drive shaft rotate at 540 rpm (9 times/sec.) or 1,000 rpm (16.6 times/sec.)

Why is the PTO dangerous?

The fast rotation speed, operator error, and lack of proper guarding make PTOs a persistent hazard on farms and ranches. Injuries that can be sustained from PTO incidents include severe contusion, cuts, spinal and neck injuries, dislocations, broken bones, and scalping. Some incidents can result in fatalities.

What is the function of PTO?

Power take-off (PTO) is a device that transfers an engine’s mechanical power to another piece of equipment. A PTO allows the hosting energy source to transmit power to additional equipment that does not have its own engine or motor. For example, a PTO helps to run a jackhammer using a tractor engine.

Can you reverse the PTO on a tractor?

Registered User. Unfortunately PTO’s run in one direction only – your experience is one of the reasons hydraulic post hole drills (PHD’s) are popular as they’re reversible to back out of any trouble.

How do I choose the right PTO?

Determine the PTO percentage by dividing the speed of the driven equipment by that of the engine. You figure out the proper torque rating by multiplying the horsepower of the driven equipment by the engineering constant of 5,252, then dividing it by rpm.

How is PTO horsepower calculated?

A PTO’s horsepower is directly proportional to the output shaft rpm. Therefore, the faster it turns, the more horsepower is produced. The formula to determine the horsepower (hp) is: hp = torque (T) x rpm ÷ 5,252.
