Mechanical treatment of hay in swaths and windrows has two immediate objectives: to accelerate the drying rate of the material in order to reduce the risk of damage by inclement weather, and to ensure evenness of drying of stems and leaves. Mechanical hay tedders came into use in 1850. Many new developments in farm machines have appeared since that time. This study was made to determine the relative effectiveness of modern forage harvesting machine treatments in accelerating the drying of hay in swaths and windrows. Because of the influence of climate on the effectiveness of hay treatments, experiments were conducted at four widely separated locations in Ontario (lat.42 to 47.5) so as to ascertain the effectiveness of treatments within the hay-growing area (3.3 million acres) of the province.
