Centre/rear PTO are the same. A drive shaft takes the drive to the rear PTO.
Overdrive uses the PTO so you cannot have a rear/centre PTO and overdrive unit.

Front PTO (winch) is direct from the engine.

There's always the exceptions, however everything that Colin suggests is correct.

Sometimes a front PTO drive is achieved by drive shaft arrangement running alongside the engine/gearbox to a PTO on the transfer box.

There is also a bottom PTO that takes power from underneath the transfer box, where the bottom coverplate is located. These can drive forward, to the rear or to the side in the case of the LT95 box on the Land Rover 101.

With a bottom PTO, you can also use an overdrive unit in the rear PTO hole.

Just searching the interweb for some colour pictures for you Brad and found this.

Explaining images in Colin's link.

Centre PTO.


This is a rear PTO, the assembly at the top (pictured upside down) mounts on the rear cross member and is connected to the centre PTO by a drive shaft through the big holes.


Centre PTO forward facing output (also pictured upside down).


This is a bottom PTO - rear facing (The thing circled in red is a standard centre PTO) the bottom PTO is the thing pointed to with the red arrow.
