In some embodiments, a system includes a housing, a cutting assembly, a tine assembly, and an auger. The cutting assembly includes a plurality of axially-aligned cutting portions and a plurality of projections extending distally relative to the plurality of cutting portions and configured to urge a non-stalk portion of a plant vertically upward relative to a stalk portion of the plant. Adjacent projections of the plurality of projections extending distally from opposite sides of each cutting portion define a receiving space aligned with each cutting portion within which the stalk of a plant can be received to be cut by the cutting portion into a first plant portion and a second plant portion. The tine assembly can be rotated to urge the first plant portion into the interior space of the housing; and an auger can urge the first plant portion toward and through a rear opening.
