1. High Efficiency: Each lawn mower can typically mow over 0.5 hectares per day, making it 16 times more efficient than manual weeding.
2. Better Economic Returns: Due to its high rotation speed, the lawn mower effectively cuts weeds in orchards, especially tender ones. Generally, weeding three times a year is sufficient to meet basic needs.
3. Reduced Costs: The initial investment for a lawn mower is 3000 yuan. Based on 500 hours of normal use, including fuel and labor costs, the cost per 667 square meters (mu) is 6 yuan, while manual weeding costs 40 yuan per 667 square meters (mu), a difference of 34 yuan. With three weeding sessions per year, using a lawn mower saves over 100 yuan per 667 square meters (mu).
4. Soil and Water Conservation: Manual weeding with hoes often causes soil erosion because it loosens the topsoil. This erosion is even more severe on terraced slopes. Using a lawnmower, on the other hand, only cuts the above-ground parts of the weeds, having almost no impact on the soil surface. Combined with the soil-binding effect of the grass roots, this is extremely beneficial for soil and water conservation.
5. Increased Fertility. When using a lawnmower, weeds should be cut only after they have grown to a certain height. The large amount of cut weeds can be used as mulch in the orchard and as organic fertilizer, increasing soil fertility.
