The term 'Harvest Machine' refers to two pieces of agricultural equipment: the REAPER and the BALER. The REAPER is a machine used to cut and collect crops such as wheat, barley, oats, and rye. It cuts the crop and collects it into a bundle, which can then be transported to a storage facility. The BALER is a machine used to compress and bind the crop into bales for easier transport and storage. Both machines are essential for efficient harvesting of crops.
