Young Blonde Girl In The Barn With Hay

Modern mechanized hay production today is usually performed by a number machines. While small operations use a tractor to pull various implements for mowing and raking, larger operations use specialized machines such as a mower or a swather, which are designed to cut the hay and arrange it into a windrow in one step. Balers are usually pulled by a tractor, with larger balers requiring more powerful tractors.
Mobile balers, machines which gather and bale hay in one process, were first developed around 1940. The first balers produced rectangular bales small enough for a person to lift, usually between 70 and 100 pounds each. The size and shape made it possible for people to pick bales up, stack them on a vehicle for transport to a storage area, then build a haystack by hand. However, to save labor and increase safety, loaders and stackers were also developed to mechanise the transport small bales from the field to the haystack. Later, balers were developed capable producing large bales that weigh up to 3000 pounds.
