Various agricultural machinery and equipment have replaced the original human labor, which has doubled the agricultural production efficiency. Although agricultural machinery and equipment need to have the performance of general motor vehicles, general motor vehicles cannot meet the needs of agricultural machinery and equipment. This is because the environment in which agricultural machinery and equipment operate is mostly soft soil or fields full of crops, or even paddy fields full of mud and water.
