However, some growers have a small planting area, which is generally used for domestic livestock, or planted in areas with uneven terrain. Large-scale machinery cannot be used for harvesting, or the cost is too high and it is not conducive to use. Manual harvesting is required, which is time-consuming and labor-intensive, increases the planting cost, and reduces the actual income effect of alfalfa."

[0057] It can be clearly known from the technical issues in the above-mentioned patent documents that large-scale agricultural machinery is generally used for harvesting alfalfa. However, some growers have small planting areas, or some growers plant in areas with uneven terrain, which is not conducive to harvesting with large-scale agricultural machinery. When large-scale agricultural machinery cannot be used for harvesting, manual harvesting is required.
