[0002] A hay cutter is a mechanical device used to chop plant materials such as hay, silage or straw. It uses blades to cut long strips of feed into short segments to facilitate animal consumption, especially for herbivorous animals such as cattle and sheep. Chopped feed is easier for animals to eat, greatly reducing the waste caused by overly long feed.

[0003] The existing grass cutter is usually unable to adjust the length of grass as needed when cutting grass, resulting in inconsistent length of grass cut, which affects the subsequent use effect. In addition, the traditional grass cutter has a complex structure and is inconvenient to operate, making it difficult to meet the needs of modern agriculture. Summary of the invention
