An agricultural windrower includes a traction unit having a frame. A cutting platform has a longitudinal extension, a feeder opening associated with a first mounting location, and a first hitch at an end of the cutting platform associated with a second mounting location. A lift assembly carried by the traction unit frame is configured to mount with the cutting platform at the first mounting location. An articulated transport arrangement is mounted to the traction unit frame. The articulated transport arrangement includes a second hitch configured for mating with the first hitch, and at least one actuator for coupling between and adjusting a relative angular orientation between the frame and the cutting platform when the first hitch and the second hitch are mated together.
