Problems solved by technology

[0004] Among the various components of the mowing machine, the mowing head is the main working part, and the mowing head is provided with a mowing rope. The mowing rope is the main structural part for mowing grass. The mowing head fixed with the mowing rope is easy to shake off, and the service life of the mowing head is generally very short. Therefore, a mowing head with a stable connection structure is urgently needed to improve the service life of the overall equipment
