Disclosed is a two-component power take-off (PTO) coupling system for efficient and simplified attachment of implements to a power take-off system of a tractor or other prime mover, having a first component to be attached to the PTO shaft of the tractor or other driver and a second component attached to the implement to be coupled. The coupling system serves to eliminate the difficult task of attaching or detaching a power shaft on a rotary driven farm implement such as a rotary cutter, tiller, generator, pump, etc. to tractor power take off (PTO) or any other driver that has an auxiliary splined power out-put shaft. It is designed for any application in any industry that requires frequent connecting or disconnecting of a rotating shaft to transfer power or torque. The coupling system can accommodate two different series PTO shaft types for example, if the implement has a type two (2) shaft but the owner's tractor is a type one (1) the coupling system can be adapted to accommodate both.
