Everything You Need To Know About Tractor PTO

Let's Get Into Details of Tractor PTO

A tractor is used not only to pull implements for tillage operations and crop sowing, but also to power stationery and moving equipment for operations such as crop threshing, pumping water from tube-wells, spraying, rotavator, and others.

A power outlet is usually located at the back of the tractor. Power Take Off is the name given to the power outlet (PTO). International Harvester Company first introduced PTO in 1918. In India, the PTO is usually located on the back side, but in developed countries, a front PTO is available for powering front-mounted attachments.

The gearbox sends power to the PTO shaft. The gearbox countershaft is typically extended out to the rear side to serve as the PTO outlet.

The standardization of the PTO speed is necessary so that the equipment can be designed around the given speed. Threshers, for example, are supposed to run at a specific peripheral velocity of the threshing cylinder. The pulley configuration is designed with the standard PTO speed in mind.

Here we have listed all the types of PTO available in India 

Economy PTO (EPTO) 

This feature enables the operator to operate the PTO at 540 rpm while running the engine at a lower engine rpm than the standard, PTO-rated speed. Economy PTO enables the tractor to operate at the required 540 rpm at the PTO while reducing engine rpm, saving fuel, reducing vibration, and reducing noise.

The 540 economy is ideal for a variety of tasks such as mowing, baling, and tilling. The 540 economy setting is incompatible with the full advertised PTO horsepower (hp). If maximum PTO horsepower is required, the tractor should be operated in standard 540 modes.

Live PTO 

A live PTO typically has a two-stage clutch. When you depress the clutch halfway, the transmission stops, but the PTO continues to spin under load (not just free spin). If you fully depress the clutch, the PTO will also come to a halt. This is extremely useful when mowing because it allows you to stop, change gears, back up, and so on while the mower continues to receive power.

If the PTO is not "live," it will lose power whenever the clutch pedal is depressed. Because the PTO is always directly connected to the transmission, an overrun clutch is required if you use a high momentum implement such as a mower.

Independent PTO 

An electric switch controls an independent PTO. The PTO can be turned on and off with the switch, and the clutch pedal does not affect the PTO.

Reverse PTO

A Reverse PTO can be turned in the opposite direction by using a lever or button. This is critical when using implements that can become stuck, such as a post-hole digger or thresher.
