  • Patent number: 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.

  • Patent number: 11420489
    Abstract: An implement mount for height adjustable mounting of an implement to a vehicle. The mount features a hitch coupler for mating with a single-point hitch of the vehicle to reach longitudinally therefrom, and a guide frame defining at least one guide slot lying transverse to the longitudinal direction of the hitch coupler in an upright orientation. At least one link arm is pivotally supported on the hitch coupler, and an implement carrier is coupled to the link arm proximate a rear end thereof. A follower arrangement is engaged between the link arm and the guide slot to constrain movement of the implement carrier to movement along the guide slot. Pivotal movement of the link arm in a first direction lifts the implement carrier along the guide slot, while pivotal moment in a second direction lowers the implement carrier along the guide slot.

  • Publication number: 20180192572
    Abstract: A conversion unit is used for indirect attachment of a mounted implement to a working machine. The mounted implement features a single-point connector, while the conversion unit features both a multi-point mounting arrangement configured for removable coupling to a multi-point attachment arrangement on the working machine, and a single-point coupler configured for removable coupling to the single-point connector of the mounted implement. With the conversion unit in an operating position attached to the attachment arrangement of the working machine, coupling of the mounted implement to the conversion unit via engagement of the single-point coupler with the single-point connector indirectly attaches the mounted implement to the working machine in a mounted position thereon.
