Abstract
A connection mechanism is provided for connecting an implement to a tractor PTO. The connection mechanism includes a PTO stub shaft, a coupler frame, an adapter holder, a PTO adapter shaft, and a resilient member. The coupler frame is adapted to be attached to the implement. The adapter holder is mounted to the coupler frame and is pivotal and slidable with respect to the coupler frame. The adapter holder receives and rotatably supports the PTO adapter shaft. The PTO adapter shaft has adapter splines. The PTO stub shaft has stub splines for meshing engagement with the adapter splines. The resilient member is coupled between the coupler frame and the adapter holder, and is biased to urge the adapter holder and the PTO adapter shaft towards the PTO stub shaft.
