What does "PTO" stand for?

Hi, cliffb!

I believe that it means a device that transfers power from an engine (as in a tractor or other motor vehicle) to another piece of equipment (as to a pump or jackhammer).

I.E. - Power Takeoff.

Please see PTO - definition of PTO by the Free Online Dictionary, Thesaurus and Encyclopedia. (http://www.thefreedictionary.com/PTO) and power takeoff - definition of power takeoff by the Free Online Dictionary, Thesaurus and Encyclopedia. (http://www.thefreedictionary.com/power+takeoff)

Thanks!
