A harvester has a main frame defining a front and a rear, and an inlet for receiving first portions of a crop. The inlet is disposed proximate the front of the main frame. The harvester also includes a separator for processing the first portions, at least one outlet downstream of the separator for ejecting the processed first portions, a boom extending proximate the front of the main frame for reaching un-processed crop, and a topper coupled to the boom for cutting second portions of the crop. The topper includes a cutter for cutting the second portions, a conveyor for receiving the second portions from the cutter, and an outlet disposed proximate the conveyor. The conveyor is configured to transport the second portions towards the outlet for ejecting the second portions towards the field.
