Patent ID: 11448264

Abstract:
A coupler for operatively interconnecting an externally splined power take off (PTO) shaft of a prime mover and a driveline of an implement that is configured to be driven by the prime mover so as to operate the implement comprises a smooth bore arranged to receive the splined PTO shaft and at least one spline-forming member which is movable in a radial direction relative to the bore between a working position for mating with a respective spline of the PTO shaft and a retracted position in which the spline-forming member is free of mating engagement with the splined shaft. There is also provided at least one locking member which is radially movable in a similar fashion to the spline-forming member between matingly-engaging and non-matingly engaging positions relative to a circumferential groove in the PTO shaft. The locking member is coincident with the spline-forming member circumferentially of the bore.
