摘要： An articulated towing apparatus pulls a rotary driven implement in a forward working direction across a ground surface behind a towing vehicle. The apparatus includes a longitudinal frame pivotally connected at a leading end to the towing vehicle by a coupling frame and pivotally connected at a trailing end to a wheeled frame that supports the implement thereon. The coupling frame defines lateral and vertical pivot axes between the longitudinal frame and the towing vehicle. A drive line, connected between a power take-off of the towing vehicle and the implement, includes (i) a longitudinal drive shaft extending at a downward slope, and (ii) an output for connection to the implement that is rotatably supported on the wheeled frame.
