Just a tad more information. After hay was mowed, it was allowed to lie on the ground on top of the stubble to dry. Meanwhile the farmer paced the ground, prayed that it wouldn't rain, and in general was a real bear to get along with. When the hay had dried sufficiently, the dump rake was used to pull the hay together into piles. Then the farmer with the assistance of children or wife would come along with a hay rack and load up the loose hay, carry it to a central location and pile it up into a hay stack. This was a real work of art, as the hay had to be compacted and the top had to be crowned to shed rain. With the advent of tractors and front-end loaders with hay tines (long, wooden tines), dump rakes were sometimes used to pull the hay together into piles or windrows so it could be picked up and transported to the site of the hay stack. Side-delivery rakes replaced the dump rakes because they were much faster and fluffed up the hay better so it would continue to dry in the windrows.
