The loss of grain in the field resulting from windrowing and combining operations has been the subject of much research since this harvesting system was introduced (4). Based on previously reported research methods (9), which were used later in combine performance studies (2, 8), preliminary field studies were conducted at Swift Current in 1948 and 1949 with the windrower and combine to develop a technique for determining and classifying harvesting losses. These were classified as natural and mechanical losses, the mechanical loss being further subdivided into windrowing, pickup, and combining losses (4). Pickup loss and combining loss have been renamed
