[0041] The blade 1 and the cutter disc 4 are detachable, and a detachable structure that can be connected to the cutter disc 4 is provided on the blade 1, so that the blade 1 can be easily replaced without repeatedly disassembling the cutter disc 4. Each time the blade 1 is worn, the blade 1 can be replaced without replacing the entire cutter disc 4. This is convenient and fast, and is easy for users to replace. In the mowing system composed of the blade 1 and the cutter disc 4, only the blade 1 is a consumable. Replacing the blade 1 alone can reduce the maintenance cost of the mowing system and reduce waste.

[0042] Furthermore, a connecting piece is provided on the blade 1 and a matching piece is provided on the cutter disc 4, and the blade 1 is snap-connected to the cutter disc 4; it is easy to operate, allowing the user to quickly install and remove the blade, thereby improving maintenance efficiency.

[0043] Specifically, the connecting member includes a first buckle 211 disposed on the left side of the blade 1, and a second buckle 212 disposed on the right side of the blade 1;
