How do you dry grass to make hay?

To dry grass for hay, first cut it when it is mature but not overly dry, ideally during a sunny, dry day. Spread the grass in a thin layer on the ground or use a hay rake to create windrows, allowing air circulation for faster drying. Turn the grass periodically to ensure even drying, and monitor moisture levels; it should be at about 15-20% moisture before baling. Once dried, store the hay in a cool, dry place to prevent mold and spoilage.
