sentences:  When using farm equipment rather than hand-harvesting, a swather cuts the alfalfa and arranges it in windrows.In areas where the alfalfa does not immediately dry out on its own, a machine known as a mower-conditioner is used to cut the hay.The mower-conditioner has a set of rollers or flails that crimp and break the stems as they pass through the mower, making the alfalfa dry faster.
