[0002] At present, large tomato harvesters are used for harvesting tomatoes, which greatly improves the harvesting efficiency. However, before the harvest season arrives, the tomato vines have covered the ground, and the vines on the walking path of the harvester need to be turned onto the ridge to prevent the vines and tomato fruits on the path from being crushed by the harvester. Previously, manual work was used to turn the vines on the walking path of the harvester onto the ridge, which was time-consuming and labor-intensive. Now, it is difficult for farmers to find workers to turn the vines in time during the harvest season. Even if workers are found, the wages are increasing year by year, which affects the economic income of tomato planting and farmers.

[0003] In recent years, in order to realize the mechanization of turning the vines, many people have tried to make vine turning machines, and several agricultural machinery manufacturing personnel who have developed vine turning machines have also been contacted. After several years of testing, none of them have been successful.

The above-mentioned existing tomato vine turning machines all have a triangular wedge-shaped head at the front end that penetrates under the vines and then pushes the vines apart with two symmetrical inclined surfaces to form a path for the walking wheels of the harvester to walk on, thereby avoiding crushing the tomatoes.

[0004] This simple form of vine turning machine can barely push out a lane in places where the tomato vines are relatively sparse, but before the tomato harvest, the vines on most plots are already very dense, and the pushed-out vines will bounce back after the vine turning machine passes through, making it impossible to form a path suitable for the harvester to walk on. This is a common problem with this type of tomato vine turning machine, and therefore this type of tomato vine turning machine has not been widely applied despite being designed for many years.
