what way does a pto shaft turn on a tractor??

According to Acepumps.com, a tractor PTO shaft rotates in a clockwise direction

There are three basic types of PTO control on a farm tractor:


The simpliest, and earliest, form of PTO is the transmission PTO. The PTO shaft is directly connected to the tractor's transmission. The PTO is only working when the tractor's clutch is released, so if you take the tractor out of gear while slowing down the PTO will stop working. This is a disadvantage in applications such as mowing.

Live (two-stage clutch)

A live PTO works with the use of a two-stage clutch. Pressing the clutch half-way will disengage the transmission while pressing it fully will disengage the transmission and the PTO. This allows the operator to slow down or change gears while the PTO is still operating.


An independent PTO means that the PTO shaft is controlled with a separate clutch. As with a live PTO, this allows for full control over the tractor while separately controlling the PTO. There are two major types of independent PTO; mechanical and hydraulic. A mechanical-independent PTO uses a separate on-off selector, in addition to the PTO control lever. Often the tractor must be stopped or off to change this selector position. A hydraulic-independent PTO uses a single selector.

Tip! The Power Take-Off (PTO) shaft is an efficient means of transferring mechanical power between farm tractors and implements. This power transfer system helped revolutionize North American agriculture during the 1930s. It is also one of the oldest and most persistent hazards associated with farm machinery.
