Abstract
An aerator for crops such as hay which is pulled by a tractor or other vehicle. The aerator includes a first header conveyor to lift a first swath from the ground onto the first header conveyor. A first hitch extends between the tractor and the first header conveyor. A first rear conveyor transports the swath from the first header conveyor and thereafter returns it to the ground. A second header conveyor lifts a second, adjacent swath from the ground onto the second header conveyor. A second hitch extends between the first hitch and the second header conveyor. A second rear conveyor transports the swath from the second header conveyor and thereafter returns it to the ground.
